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).
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.
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
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.
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.
