GGU-SLUGTEST: Cooper (Ramey/Dougherty/Moench)" menu item"

The title of this menu item reflects the evaluation model selected in "Type curves/Cooper (Ramey/Dougherty/Moench)" .

The "Test design after Cooper" dialog window that opens when "COOPER" is selected asks for the permeability and the storage coefficient. In addition, you can enter the increase for a fictitious test, as well as the water level at the end of the test. Finally, you enter the number of data per logarithmic decade.

After confirming with "OK" a new dialog box opens, where you enter the number of Stehfest points. The type curve parameter alpha shown on the screen was determined by the program from your well data (menu item "Edit/Test data") and the storage coefficient.

After confirmation with "OK" the simulated graph is displayed together with the COOPER type curves. For test design using one of the other evaluation models RAMEY, DOUGHERTY or MOENCH operate in a similar way.
