  1. Hi,

    There are many gridding options in Rockworks and the use of each one gives different results depending on the algorithm that you choose which I find to be overwhelming since none of them are particularly attractive.  I personally like the type of grids created with SURFER (Krigging) and ArcGIS (TopoToRaster).  I have not found one in Rockworks that can reproduce either of these. I would suggest that if you have XYZ data and have plotted it in another program that creates a grid to you liking that you use the Rockworks Utilities Program to import that grid using Utilities/Grid/Import and select the source data format that you have your grid in.  There you can give it a name and follow the other steps mentioned above.  To put it in shorter terms, my experience has been gridding is NOT one of Rockworks strongpoints and needs to be improved, however it does accept grids created in other programs, which is nice.

  2. Hi,

    I see that in Rockworks 17 2D Striplogs there is an option to plot a deviated borehole vertically.  That is great, however it plots the measured depth and not the true vertical depth.  Please make it so that the measured depth is displayed but alongside the true vertical length.  I have achieved this effect by setting the azimuth constant and viewing the borehole head on so that I only visualize the effect for borehole inclination.  This method works but would be smoother if incorporated with plot vertically in the 2D Striplog option.  I suggest that there be an option for this in the borehole sections too (they plot  wells vertically but of the measured depth so adjacent boreholes are not comparable to one another).  I know that Rockworks can do this.  Please include it in your programming language (maybe it could be done with with an RCL extension that says something like .... Inclination True, Azimuth False ... or something like that).

  3. Hi. I face a similar problem when I map down hole clay samples. I have found that entering 0s works when what I want is a 2D log but if it is 3D then simply omitting values where there is no detection best. It really depends on how you want to display the data. However I would like to know what the optimum method is from an experienced Rockworks user.


  4. Hi Aditya,

    Another thing that you may want to try if it is the description of thin units that is causing you problems is to widen the column where the lithological text is plotted. If this is unpractical then you may want to try including the text descriptions as I-Text which would allow you to create multiline text and plot it alongside your lithologic column. This, in addition to Brian's suggestion, may help you out.

  5. Hi,

    I need to copy some specific information from one RW16 project to another. For example, I need to know an easy way to transfer new P-data that has been entered into one Project for 59 different wells into another Project which contains the same wells. Also, I need to know how to do the same with stratigraphy and lithology data.

    I have tried transferring p-data to a text file and then opening it in Excel to later import the Excel file to the p-data table (which worked) but would like to know if there is a simpler way of doing it. Also regarding the stratigraphy data I tried transferring it to the Utilities Datasheet to then save the rwdat file and open it up in another Project. However when I tried to transfer that new information from the Utilities Datasheet to the Borehole manager in my second Project it didn’t transfer anything. Soon I will need to do the same with some lithology data also.

    I would really like to avoid having to input all of the information again when I transfer data from one Project to another.

  6. Hi,

    Maybe you could treat each sample point as a separate borehole as rudyaboo suggests and assign a different borehole symbol to represent the different types of information that you want to map. I would also consider trying to do it from within Utilities by and then creating a point map. That way you could create different columns with different colors / symbols for representing the points depending upon that characteristic that you want to map. There is a little more versatility working with the information from within Utilities depending upon what you really want to display. Also, you cold make various point maps with the different types of information and then append the different maps into one (remember to name each one with something meaningful rather than just "point") so that you can turn on and off the layers once you have done the append process.

    Hope this can help you out.

    I would like to know you end up creating your map once you decide upon the best method.

  7. Hi David,

    I think that you could resolve the problem of strip map width by adjusting the width from within the 2D Striplog manager. That is if I understand correctly the problem that you are experiencing. If on the other hand it is the borehole location map that RW generates when you make a profile that is giving you trouble a possible solution could be using the crop tool to select only the area of the location map that you want to include.

    Hope this helps.

  8. Hi David,

    I still consider myself a bit novice Rockworks user but I have found that in Rockworks 16 Level 5 that there is an option to open up Rockplot 3D from the dropdown menú on the upper right corner of the screen that allows you to import a dxf file directly for visualization. I have not yet found how to easily manipulate a dxf file to make necesary changes (like lines with zero elevation, for example). However I imagine that it could be done with Utilities by searching for and changing the values one by one or on the contrary reverting to the original dxf file to make the corrections.

  9. Hi,

    I am plotting lables at the endpoint of my boreholes in RW3D (takeing the endpoint of each well and plotting it in RW3D with the asociated label). I would like the label to be centered with respect to the borehole itself and offset a little bit below it. I saw the options for vertical offset and %offset but nothing related to horizontal offset. I have played with the vertical offset and that gets my lables far enough below the borehole trace and the % offset seems to move the label in the horizontal plane but I am not sure how it works or if there is an easier way to center lables at the end of borehole traces in RW3D.


  10. Hi,

    I have had a similar problem plotting vertical striplogs of deviated Wells. One work around is to set the azimuth to zero and let the view angle of the 2D log be zero. That will put your striplogs in TVD (you'll need to insert a vertical scale in your 2D log to see this because all of the contact depth will still be displayed in MD if you have them turned on). So that you don't loose your directional data you can save it as a an .rwdat file. Then you could display your vertical logs as above.

  11. Hi,

    I have noticed that when I export stratigraphy data to Excel via Bulk Export I get slightly different values for unit top and base elevations when compared to the calculations done in the borehole survey. Why might this be?

    Note: The difference is greater as the distance between surveys increases and is especially off with the total depth of the well (9 meters off).


  12. Hi,

    I am having a problem that didn´t occur previouosly. With Rockware 16, Level 5

    I am copying data from the borehole survey screen to the utilities data sheet so that I can use the EasyMap tool to plot some points of interest. I know that I could do this point by point from within the borehole survey tool but my need is to plot various points so that is why I copy them into the Utilities datasheet to plot them using EasyMap, however the X and Y coordinates get all messed up (the z coordinates are alright). I have done scan datasheet and it shows the coordinates are way off. It seems as though maybe somewhere in the program the actual coordiinates in the table may be being multiplied by some factor or something. Can you help me with this?
