Pick Contacts Part 1: Setup

Step 1: Enter your known data.

In order to use the Stratigraphy Picker program for your project, you need to have some known data from which you will interpret formations. Typically this would be downhole lithology intervals, or geophysical (elog) measurements or raster logs. See Entering the Borehole Data for details.

Step 2: Build a "Practice" Hole to Hole Section (Striplogs menu)

Once your known data is entered into the Borehole Manager tabs, you should next display the data as logs in one or more hole to hole cross sections. While this isn’t an essential step, displaying your known data can be very helpful in:

These examples show some lithology-only logs in section on the left, and lithology + curve logs in section on the right. They were created using the Striplogs | 2D Striplog Section program.

Once you have your hole to hole section(s) displayed in a RockPlot2D window, take a good look at the logs, pick up a pencil and write down the names of the formations or units that you will be picking.

Step 3: Define Stratigraphy Types

With a good idea of the look of the existing downhole lithology or geophysical data, you need to define the Stratigraphy "Types" which includes the names of the formations, from the surface downward, that are represented in your project. When you run the Stratigraphy Picker program (next step) the program will read the current Stratigraphy Types Table and display its formations as the ones that will be picked.

! You can modify the Stratigraphy Types from within the Stratigraphy Picker program, but it's still advisable to (at minimum) rough-in your formation names beforehand.

See Stratigraphy Types Tables for details.

Step 4: Set Up the Formation Picker Display

Step 5: Select the Wells to be Displayed
