StratWorks Tutorial

StratWorks is an interpretation package developed by Landmark for use in correlating logs, building cross-sections and creating maps. This exercise will focus specifically on building a cross section and printing out a basemap of the wells used, showing the line of section. Keep in mind that there are many other uses for StratWorks and I will only touch on the most important points, it would be to your advantage to look at the course manuals by my desk in 543 Deike for specific details and more information.

1. Log into Landmark

2. Change project to the one you would like to work in

3. Before moving on into StratWorks it’s a good idea to make a list of the specific wells that you are going to want to work with in creating your cross-section.

4. On the main Landmark menu: Data -> Management -> Well List Manager

5. Create a well list for the wells of interest (see the manual for specifics).

6. Go to Applications -> StratWorks 7. In StratWorks, you must first create a Stratigraphic Column

8. From the StratWorks command menu, select Utilities ->Strat Column Editor

9. Select Column -> Options, select your scale and make sure Definition Mode is selected.

10. Select Column -> Column Management

11. Choose Add, select which surfaces to add to your strat column, you can change the color, line width and type of surface in the surface parameters box. Move the cursor into the Strat Column Editor and press button one to move the surface up and down and release the button to post the surface on the strat column. You can remove and delete surfaces in Column -> Column Management ->Remove

12. To create a strat column with ALL the available surfaces, select Column -> Auto-Place Surfaces

13. Once you have added all the surfaces you would like you should save your strat column by clicking on Save Column in the Column Management box.

14. You can also create faults in the Strat Column Editor by selecting Column -> Faults, click on Create and change the parameters to your specifications. You are making a catalog of faults to be used later as you interpret, make sure you label the faults so that you can recognize them later.

15. The next step in StratWorks is to create a Basemap. Make sure you save your column before you log out of the Strat Column Editor.

16. From the StratWorks command Menu, select Interpret -> Map View 17. Select File ->Setup

18. In here you can change your x/y values to zoom in on your Area of Interest (AOI), and you can select the picks that you set up in the Strat Column Editor. Make sure your depth units are correct and the Active Surface List is set to “From Strat Column”

19. Now, annotate the basemap using the Wells ->Surface Posting Parameters and Bottom Posting Parameters, in these parameter boxes you can change the actual postings, colors, sizes, symbols and you can also add and delete postings.

20. To post your block lines and numbers select File -> Import ZGF picture

21. In View ->Grid, Ticks, Lines and Labels you are able to add border labels, grid lines and/or tick marks to your basemap. Make sure you save your MapView session under File -> Save Session As.

22. To print your basemap, select File -> Print, change to an appropriate size, click off the “Print Only to file”, and select a plotter. Click OK

23. You can now begin to build a Cross Section. 24. From the MapView menu bar choose CrossSections -> Create Line of Section

25. Click on the basemap in the order that you want your cross section created, then label it and click on OK to save the line of section (LOS).

26. Now select CrossSections -> Display Well Projections, click on the LOS that you have created, your selected wells will now show up as the same color as your LOS.

27. Before displaying your Cross Section you will need to create a Well Template (this is not mandatory, but it will make it easier to display your cross section).

28. Open Well Template Editor by selecting Utilities -> Well Template Editor from the StratWorks main menu.

29. Select Edit -> Tracks List and select the tracks that you would like to have show on your cross section. There are many choices, including curve, depth track, bore location, pick names, pick line… you can move these tracks by clicking and dragging them in the well template editor. You can also change the track parameters by clicking on the track in the List of Tracks dialog box and selecting Edit. Make sure to save your session before exiting.

30. You are now finally ready to view your cross section. There are many features of the Cross Section application, see attached sheet for a short list. 31. From the StratWorks main menu select Interpret -> Cross Section

32. Choose File -> Setup, for your active surface list, select your LOS that you have set up. The template box will then become active, choose the template that you created in Well Template Editor. And select “From Strat Column” for the Active Surface List.

33. The display can be edited by selecting View -> Scaling Parameters, View -> Display Parameters, and View -> Overlays. Adjust the display to your liking and then click on the redisplay button on the left side of the screen or…

34. Select View -> Display Cross Section

35. To Print your Cross Section select, File -> Print and follow the same steps as you did to print your basemap.


Curve Viewing In StratWorks

StratWorks is much like Geolog in that you have to create your own well log template. The Landmark
default templates don’t work because the log curves that we have loaded in Well Data Manager do not
match the template names.

To create your own template in StratWorks, go to Utilities -> Well Template Editor.

In Single Well Viewer, choose File -> Templates -> New, then Edit -> Tracks List. Under Track Types
choose “Curve”, then “Edit”. The editor will then pop-up. You can choose up to 5 curves per track and an
unlimited number of tracks (this is the part that looks like Geolog). Select the curve that you want and
then modify the parameters in the bottom half of the page. Click OK, then “Close” the list of tracks once you
have all the curves that you want in your well view. Click File -> Save As -> MJR_Template_GR_ILD (or something
like that).

You can then view your template in one well by choosing View -> View Current Well (you can select a different
well by clicking the little arrows at the bottom of the left menu bar).

Finally you can view your new template in your cross section. In your Cross Section view, choose File -> Setup
and choose your new template in the template pull-down menu.
