RockWorks Revision History

(121) Change (06/27/06/JCJ): The names for I-Data and P-Data columns are now limited to 31 characters.

(120) Improvement (06/27/06/JCJ): The Check-Data-Integrity option will now check for duplicate values at the same depth.

(119) New Feature (06/27/06/JCJ): A function to fill in zero-thickness stratigraphic layers is now available within the Stratigraphy menu. This function will insure that all stratigraphic layers exist for all boreholes. If a stratigraphic layer is missing, it will be added with a zero-thickness.

(118) Bug Fix (06/27/06/JCJ): The Fill-In-Stratigraphy utility no longer duplicates the first stratigraphic layer within the first borehole.

(117) Bug Fix (06/27/06/JCJ): The Check-Total-Depths utility no longer sporadically fails.

(116) Bug Fix (06/27/06/JCJ): The Import dialog box no longer stays open if an error occurs.

(115) Bug Fix (06/27/06/JCJ): Adding I-Data and P-Data names no longer generates an error when updating the min/max values.

(114) NEW FEATURE (06/27/06/JCJ): A new program titled "GDS" has been added to the Borehole Manager / Import menu. This program is used to import Geological Data Services (GDS) format files into the RockWorks Borehole Manager. There are two supported file formats; GDSII, a set of 80 character records for each well and Township & Range Flat file, one comma separated record for each well. This data is not supplied with the RockWorks program; you must contact GDS for purchasing details.

Menu Options

GDSII File Format: Click here to browse for the GDS-supplied well data file. This file may have the file name extension ".dat".
GDS Flat File Format: Click here to browse for the GDS-supplied well data file. This file may have the file name extension ".csv".
Overwrite Options: Specify what should happen if the import file references the same well names as already exist in the current project folder.

o Skip Existing Files: Program SHOULD NOT overwrite any existing well records that have the same names as wells being imported. For example, if there is already a well named "1234567" in the project, the program should not import any new data flagged for a "1234567" well, and the original well's data will be left intact.

o Replace Without Warning: Program SHOULD overwrite any existing well records that have the same names as wells being imported. For example, if there is already a well named "1234567" in the project, the program SHOULD import new data flagged for well "1234567", overwriting the existing data. Be sure about this.

o Replace With Warning: Program should warn you that a well record with that name already exists, and give you the opportunity to choose whether to overwrite or not. For example, if there is already a well with the ID "1234567" in the project, the program will warn you that new data for that well exists.

o Create New Record Name: If a well record exists, the program will create a new record (with a new ID) for the imported data. For example, if there is already a well named "1234567" in the project, the program will append "_1" to new data with that ID (creating a record named "1234567_1").

· Clean Stratigraphy Options: These settings will affect how the stratigraphic units will be imported.

o Match Tops and Bottoms: Choose this option if you want RockWorks to fill in or adjust stratigraphic tops and/or bases, based on the unit immediately above or below.

o Import As Is: Choose this option if you want the stratigraphic tops and bases to be imported as-is from the source file.

How-To Summary

Access the Borehole Manager.
Open the project folder (if necessary) in which the well records are to be created.
Choose the File / Import / GDS option.
Enter the requested menu options, described above.
Click OK to continue.
A separate borehole record will be created for each well number, based on the overwrite options you specified.
The program will import the following data:
1. The following fields will be recorded into the Borehole Manager Location table's fields:
  - Well Name and Number: Recorded into the Name field.
  - Symbol: This is selected based on the well status recorded in the import file, and the entries in the Well Status Table in RockWorks. If no well status can be determined, a default symbol is selected.
  - Elevation and Total Depth
  - Longitude and Latitude, if available.
  - Range, Township, and Section numbers. (Survey and Block for Texas will be recorded in the Comments field.)
  - Location Description: Recorded in the Legal Description field. (When using the flat file format and there is information for both Footage and Quarter Calls, then the Footage will go into the Legal Description field and the Quarter Calls into the comments.
  - API Number
2. The following fields will be recorded into the Borehole Manager Location table, Comments field:
  - Operator information
  - Elevation Reference
  - Completion Date (YYYYMM)
  - Well Status
  - State, County
  - Field Name
  - Formation at Total Depth
3. Stratigraphic top depths, and formation names, will be recorded to the Stratigraphy data table.
4. The formation names listed in the import file will be written to the database's Stratigraphy Type Table.
5. In the GDSII format the deleted record (DEL), thickness (THK), coal thickness (COL), repeated tops and fault records are ignored. The information in these records do not exist in the flat file format.
Post import:
1. You will be prompted to review the Stratigraphy Types - it's a good idea to do so. The importer will record the listed formation names into the Type Table, and will do its best to list them in proper order (if available, the higher numbers are more recent strata and should be at the top of the Type Table) but you'll need to review their order and assign desired patterns and colors. The easiest way to define stratigraphic order here is by editing the Order column (1, 2, 3, 4, etc.) - this is the column upon which the Table is sorted.
  If you are importing an GDS file into an existing RockWorks project, the import program will append new stratigraphy types onto the end of the existing Stratigraphy Type Table. It will not add obvious duplicates, but take care to review the Table before modeling to order the units properly and delete duplicates.
2. Well locations: You will need to translate longitude and latitude coordinates to feet or meters (using Map / Adjust Coordinates / Longitude/Latitude -> Easting/Northing) or, if no coordinates are present at all, you will need to manually enter the coordinates for the measurement locations. Be sure your ground coordinates match your depth units (e.g. meters and meters, or feet and feet).
3. Elevations and TD: Be sure these required fields are present for all wells before you start mapping/modeling.
4. Once all of the Location data is entered for all of the wells, be sure to establish your project dimensions prior to mapping/modeling.
Once these have been entered, you can use the Stratigraphy menu tools to model and display the formation tops and bases as maps, 3D surfaces & models, profiles, sections, and fences. You can also visualize the source data on 2D and 3D logs using the Striplogs menu tools.

Other Notes:

If you are importing an GDS file into an existing RockWorks project, the import program will append new stratigraphy types onto the end of the existing Stratigraphy Type Table. It will not list obvious duplicates, but take care to review the Table before modeling to order the units properly and delete duplicates.

(113) NEW FEATURE (06/27/06/JPR): A new set of options titled "Crop" has been added to the Geological-Utilities / Map / Land-Grid / Section-Map menu.

These options provide a means for cropping the map to a selected area. At first glance, it might seem that this is already accomplished via the Southern-Most Township, Northern-Most Township, etc. settings, but ... the crop option allows the user to view subsets of townships as shown by the following example;

Cropped portion of land grid.

(112) NEW FEATURE (06/26/06/JPR): A new option titled "Rectify Image" has been added to the Grafix / Images sub-menu. This program is used to calibrate, rotate and clip airphotos and satellite images to project dimensions.

Once selected, the Rectify Image program will present the user with the following menu;

The basic idea behind this program is to take an image, calibrate it to user-defined coordinates, rotate it such that the edges are aligned to a north/south, east/west orientation, and then to clip (extract) the portion of the image that corresponds to a rectangular area of interest. Subsequent uses for the output image include backgrounds for 2D maps and draped/floating images for 3D diagrams.

The key to the calibration process is to identify three points on the image where the coordinates are known. This is accomplished by entering the coordinates for the three points into the main menu (see above) and then clicking on the three points within the image viewing window (see below);

Once all three of the calibration points have been identified (by clicking on the image), the program will rotate, crop, and save the modified image within a new file (as specified within the initial menu).

In the preceding example image (Airphoto #1), the three calibration points are shown in red. The project area is shown in orange. Once the calibration images were digitized, the following image was automatically created by rotating and cropping Airphoto #1;

(111) NEW FEATURE (06/26/06/JPR): A new option titled "RockWare LandBase" has been added to the Help / Download sub-menu. This program will download (from the RockWare FTP site) and install the new BLM-based Jeffersonian land grid files (see item #104 below).

Upon selection, this program will present the user with a dialog box that displays the progress of the downloading process.

The downloading may be aborted by pressing the "Cancel" button at the base of the dialog box.

(110) IMPROVEMENT (06/08/06/JPR): The View / Bitmap-Coordinates option within the Grafix / Images / Digitize-From-Bitmap program now lists the corner-point coordinates and the alignment of the lateral sides of the image relative to North. This is an improvement over the previous version which assumed that the images were perfectly aligned to North/South and East/West. Although this may have held true when calibrating the image via the opposite image corner points, it is inappropriate when calibrating via three known reference points.

(109) COSMETIC (06/08/06/JPR): The Edit / Bitmap-Coordinates option within the Grafix / Images / Digitize-From-Bitmap program has been moved to the View menu. Locating this option within the Edit menu implied that the user could edit the bitmap coordinates whereas the View menu implies that the subroutine allows the user to view the bitmap coordinates - which is exactly what it does.

(108) IMPROVEMENT (06/06/06/JPR): The following menus have been redesigned such that the data source (e.g. new RockWare LandBase vs. Land Grid Table), output options (map projection, output units, offsets), and map extents (min/max townships and ranges) are listed at the top of the dialog box;

Geological Utilities / Map / Land Grid / Section Map

(107) IMPROVEMENT (06/06/06/JPR): Menus that ask the user to specify a range-&-township "window" have been redesigned as follows;

The township is now listed first (to be more consistent with surveyor notation).
The township and range are now split into sub-headings.
It is now possible to use real numbers (i.e. partial townships) when specifying ranges and townships.
The "West", "East", "South", and "North" radio buttons have been removed. Instead, the user can now enter suffixes that designate the direction relative to the meridian and baseline.

Allowable Syntax:

Townships
- 13.5S
- t13.5s
- T13.5S
- T 13.5 S
- -13.5
Ranges
- 29.5W
- r29.5w
- R29.5W
- R 29.5 W
- -29.5

(106) IMPROVEMENT (06/05/06/JPR): Section acreages within land grid maps are now more accurate because the calculation is based on all of the vertices rather than just the corner-point coordinates.

(105) NEW FEATURE (06/05/06/JPR): Data from the new RockWare LandBase (see item #104 below) may now be selectively imported into a RockWorks Land Grid Table via a new import option titled "RockWare LandBase".

Please note, however, that importing RockWare LandBase data into the Land Grid Table is akin to going around the block to get next door. It's much easier to simply select the RockWare LandBase as the data source for the various applications and skip the Land Grid Table altogether. The only reasons for importing the RockWare LandBase data into the Land Grid Table is to either (1) edit the LandGrid data or (2) merge the LandGrid data with other data.

(104) NEW FEATURE (06/05/06/JPR): The RockWorks programs that deal with Public Land Survey (Jeffersonian Range & Township) data now include an option for using a special set of six binary files instead of the ASCII "Land Grid Table(s)". This database, called the "RockWare LandBase" is available for download from the RockWare web site (see item #111 above). The RockWare LandBase dataset contains section coordinates for selected range and township surveys based on data that was downloaded, concatenated, and reformatted from the BLM's (Bureau of Land Management) LSIS (Land Survey Information System). A summary of this data is contained within the following table;

(103) IMPROVEMENT (06/05/06/JPR): The Geological-Utilities / Map / Land-Grid / Section-Map program now plots the borders for irregular townships along the borders of the irregular sections. The previous version would plot straight lines connecting just the corners of the sections.

(102) NEW FEATURE (06/05/06/JPR): The Geological-Utilities / Map / Land-Grid /Section-Map program now includes an option titled "Decimal Fractions" that determines how fractional townships will be labeled.

When using the "Decimal Fractions" notation, a township or range with a "2" extension (e.g. BLM code T0352W) will be labeled with a ".5" extension (e.g. T35.5W). Conversely, when using the "Fractional" notation (Decimal Fractions = False), a Township with a 0.2 extension will be labeled with a "&1/2" extension. A "3" extension will translate to a ".75" decimal extension and a "&3/4" fractional extension. This convention is summarized within the following table;

BLM Code	Decimal Extension	Fractional Extension	Example BLM Code	Example Decimal Label	Example Fractional Label
2	.5	&1/2	T0432N,R0562W	T43.5N,R56.5W	T43&1/2N,R56&1/2W
3	.75	&3/4	T0433N,R0563W	T43.75N,R56.75W	T43&3/4N,R56.75W

(101) NEW FEATURE (05/30/06/MIW): The RockPlot/2D program now allows the user to select multiple objects by holding the Shift key in the down position while selecting objects.

(100) NEW FEATURE (05/30/06/MIW): The RockPlot/2D program now allows the user to select multiple objects by drawing a rectangle that encloses the objects to be selected. Polylines and polygons will be included if a vertex falls within the selected rectangle.

(99) NEW FEATURE (05/30/06/JPR): A new program titled "Solid -> Grid" has been added to the Geological-Utilities / Solid / Convert menu.

Given a solid model, this program will create a grid model in which the z-value represents either the highest, lowest, average, or sum of corresponding value within the solid model (i.e. all nodes which fall within the same vertical region).

This program allows the user to view, in plan-view or 3D, a virtual summary of the underlying values.

(98) NEW FEATURE (05/30/06/JPR): A new program titled "Surface Map" has been added to the Borehole-Manager / P-Data menu.

Given a P-Data solid model and a surface model (i.e. topography, paleosurface), this program will generate a grid model in which the node values represent the solid-model values where the surface model intersects the P-Data solid model.

(97) NEW FEATURE (05/30/06/JPR): A new program titled "Surface Map" has been added to the Borehole-Manager / I-Data menu.

Given an I-Data solid model and a surface model (i.e. topography, paleosurface), this program will generate a grid model in which the node values represent the solid-model values where the surface model intersects the I-Data solid model.

If the input grid model represents surface topography, then the output map might represent surface geochemistry. On the other hand, if the input grid represents a buried surface, then the output map would be a paleo-surface-geochemistry map.

(96) BUG FIX (05/30/06/MIW): The "Scan" options within the Project-Dimensions menu now include the very top of inclined boreholes.

(95) BUG FIX (05/30/06/MIW): The Borehole-Manager / Striplogs / Multi-Log-Profile location-selection menu no longer forces the endpoints to be "snapped" to the closest boreholes.

(94) IMPROVEMENT (05/30/06/MIW): The warnings and validity test for the sections, profiles, and fence-diagram have been "refined".

(93) BUG FIX (05/30/06/JPR): The Grafix / Images / Digitize-from-Bitmap program no longer generates an error message upon startup.

(92) BUG FIX (05/30/06/JPR): The declustering option within the Solid Modeling now works correctly when the high-fidelity option is activated.

(91) IMPROVEMENT (05/26/06/MMM): The "snap" option is always activated when the user is selecting vertices within the multi-log profile selection dialog.

(90) IMPROVEMENT (05/26/06/MMM): When defining a fence, profile, or section, the user must now select at least two points. If the user fails to select at least two points, a warning will be issued and the selection dialog will be kept open until the user selects at least two points or cancels the operation.

(89) BUG FIX (05/26/06/MMM): The title is properly centered above a rose diagram if the Legend option has been disabled.

(88) NEW FEATURE (05/26/06/MMM): The RockWorks/2006 User Manual is now available as a PDF download from the RockWare web site. Click here to download.

(87) BUG FIX (05/25/06/MIW): The zoom option within RockPlot/2D wasn't working when the vertical exaggeration was greater than 1.0.

(86) REMOVAL (05/25/06/MIW): The Lithology, Stratigraphy, and Well-Construction table g-values have been changed from integers to real numbers. As a consequence, the Lithology and Stratigraphy color table options have been removed from the IsoSurfaces color-table options.

(85) IMPROVEMENT (05/25/06/JCJ): The Borehole Manager P-Data tab now refreshes the data significantly faster, albeit still slow with very large data sets.

(84) BUG FIX (05/25/06/MIW): Generating an isopach could cause the program to enter an infinite loop if any of the boreholes were disabled.

(83) BUG FIX (05/25/06/MIW): Generating stratigraphic 3D elevations could send the program into an infinite loop if any of the formations contained less than two points.

(82) IMPROVEMENT (05/25/06/MIW): RCL commands are now recorded within the RW2006_Log.txt file. These commands (designated by an "<<RCL>>" prefix) provide a tool for isolating RCL errors.

(81) COSMETIC (05/25/06/MIW): An experimental suite of progams titled "Geostatistics" was inadvertently made visible in the previous release. These options have been removed.

(80) BUG FIX (05/25/06/MIW): The DXF import program no longer resized the project dimensions.

(79) BUG FIX (05/25/06/MIW): The DXF import program no longer hangs-up when polylines with less than two points are encountered.

(78) IMPROVEMENT (05/25/06/MIW): The DXF import program now offers three warning options; Abort, Ignore, and Ignore-All.

(77) COSMETIC (05/25/06/MIW): The DXF import program now shows the line numbers as it processes the data.

(76) NEW FEATURE (05/23/06/JPR): A new option titled "Resample" has been added to the Geological-Utilities / Solid / Math menu. The Solid-Resample program will take an existing grid model and create a new model based on the current project dimensions. This is accomplished in the following way; For each node within the new model, the program will locate the closest node from the original grid within each quadrant. These nodes are then used to estimate (via an inverse-distance-squared algorithm) a value for the new node. Unfortunately, this program is outrageously slow (assuming that the output model is larger than the input model) and should therefore be considered as a last resort when compared with re-modeling the original data.

(75) NEW FEATURE (05/22/06/JPR): A new option titled "Resample" has been added to the Geological-Utilities / Grid / Math menu.

The Grid-Resample program will take an existing grid model and create a new model based on the current project dimensions. This is accomplished in the following way; For each node within the new model, the program will locate the closest node from the original grid within each sector. These sectors are defined by a user-defined search angle. For example if the user specifies a 90-degree search angle, the program will find the closest point within each of the four quadrants (sw,nw,ne,se). These nodes are then used to estimate (via an inverse-distance-squared algorithm) a value for the new node.

The Grid-Resample program may be used to generate higher- or lower-resolution models based on an existing grid model. It may also be used to create grids that represent subsets of an existing grid. Grids that are larger than the original grid may suffer from projected edge effects that may be adjusted by changing the search sector angle.

(74) NEW FEATURE (05/22/06/JPR): A new tab titled "My RockWorks" has been added to the left side of the RockWorks/2006 menu. The "My RockWorks" screen is designed to provide additional information, via the web in regards to recent news, upcoming events, revisions, case studies, FAQ, etc.

(73) IMPROVEMENT (05/19/06/MIW): The positioning of vertically-exaggerated graphics has been improved within the RockPlot/2D program.

(72) IMPROVEMENT (05/19/06/MIW): Isosurface drawing within RockPlot/3D is considerably faster when used in conjunction with hardware-accelerated video cards.

(71) BUG FIX (05/19/06/MIW): The Cancel button within the main menu now resets things to their proper (modal) state.

(70) NEW FEATURE (05/19/06/MIW): The column widths within the Geological Utilities datasheet are now automatically resized (based on the first row contents) so that the data will be visible.

(69) NEW FEATURE (05/19/06/JCJ): A new option titled "LAS Multiple" has been added to the Borehole-Manager / File / Import menu. Once selected the user will be presented with the new LAS Bulk Curve Importer menu as shown by the following diagram.

This program is used to import data from all of the LAS files within a designated folder. The menu items include;

Curves to Import: Multiple curves can be listed in this list. Only the listed curves will be imported into the database.
Link Borehole on Well Name: The program will look for the borehole where the Well Name is identical to the Borehole Name.
Link Borehole on API Number: The program will look for the borehole where the API Number in the file is identical to the API Number in the database.
Add Boreholes: Add boreholes to database if they don't already exist.
Add Curves: Add curves (P-Data columns) if they do not exist within the database. Once you initiate the import, the LAS files will replace the P-Data for that borehole. At the end of the import if any boreholes were not found or the requested curve was not found a message will be displayed.
List Curves From Scan: Curves found in the scan of files will be added to the “Curves to Import” list to edit for the import process. (Ctrl-C will copy this information to the clipboard in a format that can be pasted in Excel.)
Scan Wells: Scan the designated directory and list the LAS files.

This file list will show the;

LAS filename
Well Name
API Number
Curves (from the files)
Borehole Name
API Number
Borehole ID (from the database, if found).

Once you initiate the import data in the LAS files will replace the P-Data for that borehole. At the end of the import if any boreholes were not found or the requested curve was not found, the results will be shown within a report as shown below;

This importer is designed to import all the LAS files in a given directory. In order to do this, some simplifying assumptions are made, limiting the flexibility of what gets imported. It will look for an existing borehole based on the borehole Name field equaling either the Well Name or the API number. You can choose to add a new borehole if the search for an existing borehole fails to find a match (“Add Boreholes if they do not exist” check box). If a new borehole is added; the Easting, Northing and Elevation will be imported as zero; the Total Depth will be set to the Stop Depth; and API Number set to the API number. All other Well and Parameter Information Block data will be ignored.

Only data for the curves listed in the “Curves to Import” box will be imported. You may type in the curves to import or pre-scan the files for what curves exist in the LAS files. To pre-scan the files for curves, check the “List curves from scan” check box and click “Scan Wells” button. You may delete any curves from the list you do not want to import. The curves listed (one per line) must be the mnemonic from the file’s Curve Information Block, and will be imported to the Point Data column with that name. If you check the “Add Curves if they do not exist” check box, new Point Data columns will be added if they do not exist during the import.

The “Scan Wells” will pre-scan the LAS files and list the filename, Well Name, API Number and what curves exist in each file, for all the files in the directory. The last three columns Borehole, API and BhId will have RockWorks data if a pre-existing borehole is found in the Borehole Manager based on what you choose to link on; the Well Name or API Number. BhId is the RockWorks internal id number for the borehole. You do not need to pre-scan the files, the result is purely informational to see how the Bulk Importer will link to existing boreholes and what curves are available.

Choosing to import LAS files one-by-one using the regular LAS importer gives much more flexibility as to what to import and where the data goes in RockWorks.

(68) IMPROVEMENT (05/19/06/JCJ): A modal status dialog box is now displayed whenever the program is importing LAS data. This prevents the user from using other functions (which can "confuse" the program) until this operation is complete.

(67) IMPROVEMENT (05/19/06/JCJ): A modal status dialog box is now displayed whenever the program is calculating the XYZ values for the borehole entities. This prevents the user from using other functions (which can "confuse" the program) until this operation is complete.

(66) BUG FIX (05/19/06/JCJ): The File / Create-New-Project option no longer fails if the user types in the name of the new project directory instead of using the directory-lookup dialog to create the folder.

(65) IMPROVEMENT (05/19/06/JPR): The Geological-Utilities / Planes / Stereonet / Colored-Intervals / Skip-Low-Values option no longer produces a "ragged' edge at the cutoff boundary.

(64) BUG FIX (05/19/06/JPR): The Geological-Utilities / Planes / Stereonet / Colored-Intervals / Skip-Low-Values option now works correctly. The previous version would ignore the Skip-Low-Values setting and plot all values.

(63) BUG FIX (05/17/06/MMM): The rp2d_rockworks.png file is now included within the Samples folder. This file is referenced by the help/tutorial section that shows how to add corporate logos to reports.

(62) BUG FIX (05/17/06/JCJ): The Borehole-Manager / Import / RockWorks/2004 program now skips non-numeric data within I-Data blocks. Thanks John!

(61) IMPROVEMENT (05/17/06/JPR): When automatically setting the project dimensions by scanning the boreholes or the Geological Utilities datasheet, the program will attempt to deal with single-point datasets by looking at the range of x, y, and z-data. If any of these dimensions are zero, the program will attempt to user the other non-zero ranges to expand the project dimensions to something that is usable. - Thanks Roger!

(60) BUG FIX (05/16/06/MIW): The program no longer fails to read non-US number formatting for the Project Dimensions.

(59) BUG FIX (05/16/06/MIW): Various dialog-boxes and datasheets now properly resize with selected computers when Large Fonts are being used.

(59) BUG FIX (05/16/06/MIW): Rose diagram titles are now plotted.

(58) BUG FIX (05/16/06/MIW): Importing older RockPlot/2D files no longer generates an error when importing lines with zero length.

(57) IMPROVEMENT (05/16/06/MIW): Corrupted characters are no properly screened-out when loading tab-delimited files into the Geological-Utilities datasheet.

(56) BUG FIX (05/16/06/MIW): Templates for RockWorks/99 files no longer just set the first column header.

(56) BUG FIX (05/16/06/MIW): The RockPlot/2D / Export / raster format options now honor the current view margins. The previous version would occasionally clip/omit a border edge.

(55) IMPROVEMENT (05/16/06/MIW): The Borehole-Manager / Edit-As-Spreadsheet option now allows the user to select entire rows and columns.

(54) BUG FIX (05/16/06/MIW): The "delete" key nor works correctly within the Borehole-Manager / Edit-As-Spreadsheet option.

(53) IMPROVEMENT (05/16/06/MIW): Single dots within diagrams are now more readable within print-outs and high-resolution images.

(52) BUG FIX (05/16/06/MIW): Cell deletion within the database grids is now more consistent.

(51) BUG FIX (05/16/06/MIW): The Inverse-Distance and Multiple-Linear-Regression gridding algorithms no longer share the same fault file. This caused the program to always override the inverse-distance fault file with whatever was last specified for the MLR faulting.

(50) BUG FIX (05/16/06/MIW): The RockPlot/2D / Export / RockPlot/3D program no longer exports filled polygons as polylines.

(49) IMPROVEMENT (05/16/06/MIW): The Grafix / 3D-Utilities / Images / Drape program now accepts all common raster types. The previous version was limited to BMP files.

(48) NEW FEATURE (05/16/06/JPR): A new program called "Tube Filter" has been added to the Geological-Utilities / Solid / Filter menu.

Given a list of xyz coordinates that represent the axes of tubes (e.g. mine workings, tunnels, etc.), the Tube-Filter program will either set all nodes for a designated solid model (e.g. ore grades, lithologies, porosity) outside or inside the tubes to a null value.

Subsequent analysis of the output model via the Solid / Volumetrics program will list the volumes for material within or outside of the tubes.

For example, a tunneling operation could use this program to compute the volumes of various materials that are to be extracted from the tunnel(s).

Conversely, a mining resource model could be subjected to a tube-filter whereby the mined regions, modeled by tubes, are removed from the model by setting the regions within the tubes to a null value.

Fence diagram of block model in which nodes inside of the tubes have been set to a null value combined with a tube diagram.

The input file for the Tube-Filter program is identical to that used by the Grafix / 3D-Utilities / Tubes program. An example is provided by the "mine_workings.atd" file.

(47) IMPROVEMENT (05/16/06/JPR): A series of additional features have been added to the "mine_workings.atd" sample file. This file is designed to illustrate the Grafix / 3D-Utilities / Tubes and the new Solid / Filters / Tube-Filter (see above) programs.

(46) COSMETIC (05/16/06/JPR): The "Width" setting within the Grafix / 3D-Utilities / Tubes menu has been changed to "Tube Radius".

(45) IMPROVEMENT (05/02/06/JPR): An automatic image preview has been added to the Open option within the following menus;

Geological-Utilities / Grid / Import
Geological-Utilities / Grafix / Images / Append Raster Image
Geological-Utilities / Grafix / Images / Raster -> RockPlot/2D
RockPlot/2D / File / Import / Raster -> RockPlot/2D

(45) IMPROVEMENT (05/02/06/MIW): The RockPlot/3D program now loads the most recent help messages.

(44) IMPROVEMENT (05/02/06/MMM): The help messages have been updated.

(43) IMPROVEMENT (05/02/06/MIW): The error log now generates more detailed messages.

(42) IMPROVEMENT (05/01/06/JPR): The main application tabs (i.e. Borehole Manager, RockWare Utilities, Geological Utilities, GeoTools, and Tables), that appear along the left side of the main RockWorks menu will now display as multiple lines if the main dialog is reduced in size to the point where any tab would no longer be visible.

5/1/06 - Beta Testing Completed - Version 6.5.1 uploaded to RockWare web site.

(41) BUG FIX (04/30/06/JPR): The Geological Utilities / Linears / Lineation-Gridding program can now generate 3-dimensional diagrams of the output grid model.

(40) BUG FIX (04/29/06/JPR): The Geological Utilities / Linears / Arrow Map program no longer produces blank maps if the "Override Line Options" setting is enabled.

(39) IMPROVEMENT (04/29/06/JPR): The Geological Utilities / Linears / Lineation Map program no longer saves zero-length lines.

(38) BUG FIX (04/28/06/JPR): The Jeffersonian Land Grid Interpolator now correctly lists the reference point township. This bug has been fixed in RockWorks/2004.

(37) COSMETIC (04/27/06/JPR): The Geological Utilities / File / Import / DXF / DXF-Lineations option has been removed. It is redundant with the Geological Utilities / Lineations / Import / DXF option.

(36) IMPROVEMENT (04/27/06/JPR): The lithology modeling now includes all intervals within the boreholes even total-depth setting is in error (i.e. intervals below the TD are now included within the model computations).

(35) COSMETIC (04/27/06/JPR): "Cancel" buttons have been added to the 2D and 3D log designer menus.

(34) NEW FEATURE (04/26/06/MIW): The number of triangles generated by an IsoSurface within RockPlot/3D has been increased to approximately 35 million from less than 9 million. The display of this many triangles will require considerable patience and will also depend on the amount of available memory.

(33) NEW FEATURE (04/26/06/MIW): The Grid / Import program now includes support for Canadian 0.75-second DEMs (Digital Elevation Models).

(32) NEW FEATURE (04/26/06/MIW): The RockPlot/3D keyboard plus (+) and minus (-) keys now change the current zoom by 1.5 and 0.75 times respectively.

(31) NEW FEATURE (04/26/06/MIW): The RockPlot/3D program now includes a zoom setting within the toolbar. This option allows the user to select or manually type a zoom percentage. The stock settings are 400, 200, 100, 50, + (1.5X) and - (0.75X).

(30) NEW FEATURE (04/26/06/JPR): The Project Dimensions menu now generates red error messages when various settings don't make sense or an out-of-range error condition exists (i.e. too many nodes). Notice that you may need to scroll within a settings box to see the entire message.

(29) NEW FEATURE (04/24/06/JPR): The Filter option within the striplog menus (2D & 3D) is now listed as a checkbox (true/false) item. Although this is admittedly redundant within the sub-options, it provides a master on/off capability that is clearly apparent within the main menu.

(28) COSMETIC/REMOVAL (04/24/06/JPR): The Resampling option within the striplog menus (2D & 3D) is now a separate item within these menus (i.e. it is no longer buried within the Filters menu). In addition, the Interval Thickness option has been removed from these menus since it is redundant with the new capabilities (see below) afforded by the Resampling option.

(27) NEW FEATURE (04/22/06/JPR): The two-dimensional striplog menus now include an option for defining the resampling method that will be used when plotting I-Data bargraphs;

The effects of the resampling methods are shown within the following diagram;

Original data (5' sample interval).
2-foot resampling - weighted average.
2-foot resampling - based on closest point.
10-foot resampling - weighted average.
10-foot resampling - based on closest point.

(26) NEW FEATURE (04/22/06/MIW/JPR): All menus that generate voxel-based, three-dimensional diagrams now include an option for displaying voxels as colored points (as opposed to six-sided cubes). This capability can be very useful when rendering very large models in which the conventional voxel display is too slow.

This capability has been added to the following menus;

Geological-Utilities/Solid/Model
Geological-Utilities/Solid/Fracture-Discs->Model
Borehole-Manager/Fractures/Model
Borehole-Manager/I-Data/Model
Borehole-Manager/P-Data/Model
Borehole-Manager/Lithology/Model

Lithology model displayed as voxel midpoints (upper-left) and full voxels (lower-right).

(25) IMPROVEMENT (04/18/06/JPR): The Tools / Main Menu Configuration Wizard help messages are now installed on the host machine meaning that the user need not have access to the Internet in order to view them.

(24) BUG FIX (04/18/06/JPR): The "Show Advanced Options" setting within the Project-Dimensions menu is now "remembered" the next time the program is executed.

(23) BUG FIX (04/18/06/JPR): The Z-Nodes setting within the Project-Dimensions / Vertical-Resolution menu now works correctly (i.e. selecting "Scan Boreholes" did not use this setting).

(22) IMPROVEMENT (04/18/06/JPR): The two programs within the Borehole-Manager / P-Data / Export sub-menu (Export-to-ASCII and Export-to-Geological-Utilities) have been combined into a single program. In addition, a variety of new options (highlighted in green within the following screen-shot) have been added.

(21) IMPROVEMENT (04/17/06/JPR): The two programs within the Borehole-Manager / I-Data / Export sub-menu (Export-to-ASCII and Export-to-Geological-Utilities) have been combined into a single program. In addition, a variety of new options (highlighted in yellow within the following screen-shot) have been added.

(21) IMPROVEMENT (04/14/06/JPR): It is no longer necessary to turn on the lithology legend in order to generate volumetrics summaries within lithology models or lithology fence diagrams.

(20) REMOVAL (04/14/06/JPR): The font "Name" field has been removed from all menus that create 2-dimensional graphics. This is due to the fact that the 2-dimensional graphics font is now hardwired to Arial.

(19) REMOVAL (04/14/06/JPR): The "Label Font" option has been removed from Geological-Utilities / Map / Grid-Based-Map / 2-Dimensional / Labeled-Cells menu. This is due to the fact that the graphics font is now hardwired to Arial.

(18) NEW FEATURE (04/14/06/JPR): The Striplogs / I-Data & P-Data / Filters / Resample option now works correctly;

Left: Original data samples at 5 meter intervals.

Center: Resampled data at 1 meter interval.

Right: Resampled data at 11 meter interval.

(17) NEW FEATURE (04/14/06/JPR): The vector plotting within 3-D logs now include an option for determining how the vector lengths will be established;

Uniform: All vectors will have the same length which will be equal to the vector column radius. In this setting, the vector "value" is ignored.
Variable - % of Column Width: The vector "value" represents a percentage of the vector column radius. For example, a vector value of 50 will have a length equal to half of the vector column radius.
Variable - Real World Units: The vector "value" represents a real vector length. For example, a value of 200 will plot a vector that whose length is 200 map units.

(16) BUG FIX (04/13/06/JPR): Depth labels are now properly clipped within 2-dimensional sections and profiles.

(15) NEW FEATURE (04/12/06/JPR): The Borehole Manager / Stratigraphy / Model menu now includes an item titled "Hide Thin Zones".

When activated, the "Hide Thin Zones" option will not display portions of the stratigraphic units where the thickness is less than a user-defined cutoff. When de-activated, the program will show the full extent of the formation even where the unit has zero thickness (i.e. the "old" way).

(14) NEW FEATURE (04/12/06/JPR): The Borehole Manager / Stratigraphy / Stratigraphic-Thicknesses / 3-Dimensional menu now includes an item titled "Hide Thin Zones".

If checked, the "Hide Thin Zones" option will not display portions of the isopach where the thickness is less than a user-defined cutoff.

(13) IMPROVEMENT (04/11/06/JPR): Loading and importing data into the Geological Utilities datasheet is significantly faster, especially for large data.

(12) IMPROVEMENT (04/11/06/JPR): The "high-fidelity" option within the gridding is significantly faster and requires less memory.

(11) COSMETIC (04/11/06/JPR): The Grafix / 2D-Utilities / Append-Graphic-Image program has been moved into the Grafix / Images menu.

(10) REMOVAL(04/11/06/JPR): The Geological-Utilities / Edit / Random options have been removed. They are redundant within the Random option in the Stats menu.

(9) IMPROVEMENT (04/11/06/JPR): The Geological-Utilities / Edit / Columns / Math programs no longer converts text (e.g. "no data") to null values (i.e. -1E27). Instead, any math operations that encounter a text string are saved as blank cells. These operations include;

Absolute
Column / Column Math
Column / Constant Math

(8) IMPROVEMENT (04/11/06/JPR): The Geological-Utilities / Edit / Columns / Fix program no longer converts text (e.g. "no data") to null values (i.e. -1E27). Instead, text strings are converted to empty cells.

(7) REMOVAL (04/11/06/JPR): The "Decimal Degrees" option has been removed from the Borehole-Manager / Map / Adjust-Coordinates / Jeffersonian -> Easting/Northing menu. Given that all of the RockWorks Borehole-Manager programs are based on identical units for vertical and horizontal dimensions, we felt that allowing (or implicitly encouraging) decimal degrees for eastings and northings is a bad idea.

(6) New Feature (04/10/06/JPR): The "high-fidelity" option within the solid modeling is significantly faster (i.e. it requires about 11% of the time that was previously required) and uses half as much memory. This is especially important for very large data sets in which the program requirements exceed the total amount of RAM (Random Access Memory) thereby using the hard-drive as virtual memory.

(5) New Feature (04/10/06/JPR): The Borehole-Manager/Striplog/Section and Profile programs now include an option for adding well-construction pattern legends to the output.

When plotted in conjunction with lithology and/or stratigraphy legends, the program will automatically set the legend column widths to the largest of the 2 (or 3). This results in better looking legends (i.e. the title fonts will have the same dimensions).

(4) New Feature (04/04/06/JPR): The Borehole-Manager/Striplog programs now include an option for adding well-construction pattern legends to the output.

(3) New Feature (04/03/06/JCJ): The Borehole-Manager/Stratigraphy/Pick-Contacts program now has an option for adding new stratigraphic units without leaving the program (i.e. saving the current work, returning to the Stratigraphy Table, adding the unit, and then returning to the Stratigraphy Picker).

(2) New Feature (04/03/06/JPR/JCJ): A new command titled "SQL" has been added to the RCL (RockWare Command Language). This command allows users to add their own SQL (Structured Query Language) instructions to an RCL script. An SQL block begins with the "SQL:" command, followed by any number of lines that contain the SQL code. The SQL block is terminated by an "SQL-END:" command.

SQL commands may be used to do anything to the database, including the deletion of the entire database, corruption of the linked records, etc. We strongly recommend using the "BACKUP" command (see item #1 below) before implementing an SQL command. Just like fire, the SQL command is very dangerous but also very useful.

(1) New Feature (04/03/06/JPR/JCJ): A new command titled "BACKUP" has been added to the RCL (RockWare Command Language). This creates a backup copy of the current Borehole Manager database. It is identical to the File / Backup-Database menu option except that a confirmation dialog is not displayed.
