2. ## Volume calculations

Hi Jose, What method are you using to calculate the model volumes for each G value? For example, using the volume reported in the model properties in RockPlot3D, I found that setting a Filter from 1 to 2 includes voxels with values of 1 or 2 for a volume of 1600 , but setting the Filter from 2 to 2 gives a volume of 800. Some other things to consider: Well #2 at (0,10) puts it in the middle of the west side of the area. Did you mean to put it at (20,0) in the SE corner? What modeling method are you using? With no data in the SE corner, values are estimated from the other more distant wells. Some of the cells show a gradation from 1.0 to 1.2. 1.4, ... 2.0 near the edges with the Inverse Distance Anisotropic method. You may want to use the Closest Point method for less interpolation between values in the wells. What modeling options are you using? For example, the Superface filter truncates the model based on a grid of the well elevations. Since the grid elevation coincides with the well elevations, some cells may be nulled out. Turn off this feature for this exercise. RockWorks calculates volumes by counting the number of voxels or cells, and multiplying by the volume of each voxel. When the model is drawn, the model is truncated at the edges to match the project limits when drawn using the Solid style. The model extends past the project limits when drawn with the Voxel style since the center of the voxels are placed at the edges of the model. In both cases the volume reported is the same.

3. ## Volume calculations

Hi, everyone I'm currently using Rockworks 16 to do some test volume calculations in the I-data model. In my project i have 5 boreholes, 4 are separated 20 m apart forming a square and one is in the center. The boreholes are in coordinates X,Y: (0, 0), (0, 10), (0, 20), (20, 20) and (10, 10). All 5 boreholes have the exact same i-data: numbers 5 to 1 in descending order, each number in intervals of 2 m. The boreholes have a total depth of 10 m and are all at elevation 0, thus making the project a perfect cube. Calculating the volume manually yields that the solid generated should have a total volume of 4,000 cubic meters, and that each "interval strata" should have 800 cubic meters. I had some trouble getting a solid with a volume of 4,000 cubic meters using the aforementioned data, but after browsing a lot through the help i found that i had to adjust my node spacing and project dimensions so that i could get a volume equal to the area of my project, as explained in https://help.rockware.com/rockworks17/WebHelp/solid_nodes_v_voxels.htm . I have made 2 tests. In the first one i used the following project dimensions: node spacing as 0.1, Xmin=0, Xmax: 19.95, Ymin=0, Ymax=19.95, Zmin= -9.95, Zmax=0. Generating the solid yields the following iso-level values: 5: 800 m3 4: 1,520 m3 3: 2,280 m3 2: 3,200 m3 1: 4,000 m3 In the second test i used the following project dimensions: node spacing as 1, Xmin=0, Xmax: 19, Ymin=0, Ymax=19, Zmin= -9, Zmax=0. Generating the solid yields the following iso-level values: 5: 800 m3 4: 1,600 m3 3: 2,400 m3 2: 3,600 m3 1: 4,000 m3 Through manual calculation, each interval should have 800 m3, and thus the iso-level results should be: 5: 800 m3 4: 1,600 m3 3: 2,400 m3 2: 3,200 m3 1: 4,000 m3 Is there any reason why the program is arbitrarily "exchanging" cubic meters between the intervals? The only modelling options i am using are IDW anisotropic and G=color.

5. ## Create 3D grid - topography

Hi Laure, To display a line on a cross-section representing a surface, create a grid .RwGrd file of the surface from 3 or more points, or from Stratigraphy or Aquifers in the Borehole Manager. Specify the name of the grid file in the Section menu Plot Surface Profile option. Generating a grid file can take a long time if there are a lot of nodes in the grid. If you run out of memory, your computer can crash. You are welcome to send to [email protected] a backup ZIP file of the project generated with the Borehole Manager File | Backup Database command. Include your RwDat or other file used to calculate the topography and the full text of any error messages displayed when the computer crashes. Larger files may be uploaded to https://rockware.com/upload Regards, Tom B RockWare Inc
6. ## Creating a 3D model from cross sections

Hi Ehsan, You can digitize XYZ points on the 3D display, and create models from the digitized points in Utilities. Regards, Tom B RockWare Inc
7. ## Create 3D grid - topography

Hello , Sorry for my English .. How can we create a level like a roof of a sub-layer or a water level .. just a line in my section. Connect different depths between them. DATA allows to assign a text or values to each depth but I just want to connect these depths between her. I don't know if I've been clear… Is it normal that generating a 3D grid (topography) takes several hours ... It's endless. My topography's datasheet contains162000 rows…. my computer crashes all the time… What option should I choose? Thanks...
8. ## Creating a 3D model from cross sections

Thanks Mitch. Is it possible to create a 3D lithology/stratigraphy model from these cross sections in addition to 3D display? Is there any option for digitizing cross sections inside RW?
9. ## Creating a 3D model from cross sections

Hi Ehsan, take a look at the Utilities/Imagery/Vertical (Images --> 3D Panels). The example files are vertical_images_3D_sections_01 and 02. Mitch
10. ## Creating a 3D model from cross sections

Hi there, I have some geological cross sections from my study area in raster format which have been drawn by geologists. I was wondering if there is a way to import them into RockWorks and create a 3D geological model using them. Thanks in advance for your help. Cheers, Ehsan

12. ## "Point Sample" tool for rockworks

Hi Lionel, There are several tools in RockWorks 17 that you can use to extract data from your models. Create new boreholes where you propose to drill piles and choose the Stratigraphy | Section or Lithology | Section menus to draw cross-sections to visualize the data from your models. Use the Utilities Grid | Grids -> Stratigraphic Logs menu to extract Stratigraphy data to the new boreholes. Turn off the existing boreholes so they are not changed. Use the Utilities Grid | Statistics | Residuals menu to extract the elevation from a Stratigraphy grid at the specified XY locations. Use the Borehole Manager Striplogs | Pick Lithologic Intervals menu to pick Lithology units on a cross-section and add them to the borehole Lithology table. Use the Utilities Solid | Statistics | Residuals menu to extract the Lithology G-values at the specified XYZG locations. Regards, Tom B RockWare Inc
13. ## "Point Sample" tool for rockworks

Hi everyone, On RW17, I've created my database and generated a 3D model for stratigraphy and lithology. A that stage, I'm looking for a tool that would allow me to extract the lithology or the stratigraphy at some locations that I would have had chosen (for instance, I will drill some piles in the area and I would like to assess what lithology/stratigraphy would be at those locations). If you're used to work with Surfer, I'm looking for a tool that would be similar to "Point Sample", but would add some columns in the database for every levels of litho/strati layers. Does that tool exist already? Thank you for your help ! Best Regards. Lionel

17. ## Information about Rockwork software 16

Hello sir I am a user of your software to allow me to work on a project. my job is to correlate training to determine the different types of formations on the coastal area of abidjan. I am having problems on some points and I wanted to know if you can help me because of this work will depend my hiring in the company. Thank you for really helping me. 1- For geolocation, I am blocked on the WGS 84 which does not appear in the various UTM systems in the software. it will allow me to find the study area and the projection to better see the lithology and the stratigraphy. 2- may I have videos to better control your software because it plagues me and allows me to know how to control its handling and processing information. Thank you for this software and God bless you.
18. ## Temperature In the borehole

Hi Nikos, Enter your borehole locations, elevations, and total depths in the Borehole Manager Locations table, and enter the depths and temperatures in the P-Data or I-Data table. P-Data is "Point Data" with one depth per temperature value, and I-Data is "Interval Data" with a top and bottom depth for each temperature value. Create a solid model from the P-Data or I-Data | Model menu and specify the DTM grid as the upper truncation surface or Superface. Regards, Tom B RockWare Inc
19. ## Temperature In the borehole

Dear Tom. My questions is following my previous one (see below) I managed to project the surface temperarure (X,Y,Z, T) data from some boreholes on the DEM using the solid model, after your advice. Now I have temperature measurements at the bottom of the these boreholes (X,Y,Z2, T2). How could I make a model using the DEM and both temperatures (on top and at the bottom)? I want to study the variations in depth and laterally. Thank you in advance Nikos
20. ## EZ Topo Map coordinate change

After receiving the data we are able to discern that there was a difference in coordinate systems from the Utilities datasheet and the project coordinates (UTM meters vs UTM feet). Once that was corrected the contours were projected inside the project dimensions correctly.

Hi Paul Sent the backup to you. Let me know your thought Craig

24. ## EZ Topo Map coordinate change

Good morning Craig, Would you mind backing up your database and sending it to us at [email protected]? I would like to make sure that I am using the correct coordinate system and grid/model dimensions as well as the same setting you were using as I am working with your .rwDat to see if I can replicate the issue that you are running into. Thanks!
25. ## EZ Topo Map coordinate change

I have a 700 point xyz dataset. EZ Topo tool contours honor data but shifted way outside the project dimensions. A puzzling occurrence Thank you for insights. Craig Topo Data Set.rwDat
