  1. Hi, I am trying to export the coordinates of digitized points in RW2D to the Utilities Datasheet. I keep getting the error that the argument is out of range.
  2. Hi Heather, I forgot to mention that this will change the way your maps plot but in order to get the 2D Striplog to plot vertically and correctly you need to do this. I haven't found an easier way. To do you maps you need to uncheck the changes that you made in General Preferences to the Borehole Orientation Tab. Best Regards,
  3. Hi Heather, I have a great way of doing what you are trying to do. Go to General preferences and click on the Borehole Orientation Tab. Go to Adjust Vertical Azimuths (for what you are doing I know that you need the hole inclination but this works). Change the maximum borehole azimuth a value higher than your máximum borehole inclination (I know that you are working with inclinations but just trust me). For example I use 60 because we don't have any boreholes with more than 60 degrees inclination. You could use up to 90 degrees if your boreholes have a greater inclination than 60. Then in the replacement azimuth enter 0. This will plot your striplings vertically with the scale adjusted correctly. You can check it by measuring the distance between numbered intervals below the Kick Off Point. Really the Plot Vertical option that Alison doesn't work for this applicaiton. It has a different funcion, as she mentions. As for the I-Data not plotting, make sure that all the the required options are filled in (fill type, column width, et c.) and that the required I data category is correctly selected in the 2D Striplog Designer. Hope this helps.
  4. Control points are the known depths of the formation top and bottom. You get these from borehole data, ideally although you could create an imaginary well from a good cross section. With one or more imaginary wells well you can “define” the depth of the Proterozoic at different locations on your grid. Also it looks like there is a gap between the Cretaceous and the Proterozoic in your block model that you may need to look at. Best Regards.
  5. Hi JamesH. I used RW16 in the past and use RW17 now. There is not much difference between versions so I think that maybe these suggestions could be useful. Regarding the Proterozoic cutting through the Paleozoic that could be related to the grid you are using for the Proterozoic so one option would be to make more control points to tweak your grid. Also check the number next to your units. RW interprets lower numbers as overlying units. However you may be OK there because your legend is OK. As for the map try making the maps that you need separately and then doing an append. Another suggestion is to try different gridding algorithms. I generally get satisfactory results using Inverse Distance (Kriging doesn’t work well for me in RW). Another neat trick that you can try is gridding the data in SURFER or ARCGIS if you have them and importing the data to RW using Utilities. Best of luck to you!
  6. Hi Vincent, I think that you can just turn off the well types that you do not want to show up on your section. Remember that deviated wells do not plot properly in sections. If you have deviated wells I would suggest plotting a profile. In either case, try just turning off the wells that you do not want to project.
  7. Hi, I am using Rockworks 17 Advanced and can select the "other" coordinates for custom projection without any problem. The issue is that one of my coworkers is also using Rockworks 17 Advanced and he the tab for "other" does not come up on his computer (he can only see the options of Local, SPC and UTM). What may be causing this?
  8. I use Rockworks 17 Advanced. I can create custom projections but a co-worker that also uses Rockworks 17 advanced cannot. What might be causing this?

    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. Best Regards, Edward Hakanson
  10. 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). Best Regards, Edward Charles Hakanson Gregory
  11. Maybe you could generate a P-Text file and plot it alongside your P-Data.
  12. One thing that you might try is creating rotated text in RW2D and then linking that file to your Reportworks file.
  13. Try adjusting the VE of your model and boreholes individually and then do an append. This may work.
  14. 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.
  15. 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. Edward
