WBHP not equal to WBP when a well is shut in in Eclipse

[Shakespear]

Vino is correct

Try this with Chap.DATA

Very small rate " 'P1', 'ORAT' 0.010000 / "

In the first case you will see the pressure build up. In the second case over the same time frame it will be ZERO, just as SLB said. The well is not connected to the simulation blocks. Hence zero pressure.


You will need this in SUMMARY to see the right results
