[Help] Error when run ECLIPSE model?

[rtdixon]

Hi

i run a project in 1-poro and dual-poro , when i run 1-poro, it ok, success, but when i run in dual-poro, it have a comment: "RUN STOPPED BECAUSE A HISTORY MATCHING WELL HAS VIOLATED ITS BHP LIMIT" , then it stop.
And some message i recieve:" WELL .... HAS CHANGED TO CONTROL BY BOTTOM HOLE PRESSURE FROM TIME...." . I don't know why model change that.

anybody know can tell me how to fix that.

Thanks

When you change from poro-1 to poro-2 the well properties change so that the well can no longer produce the rate that is specified.

The well then has a higher drawdown, reaches the BHP limit and then can no longer produce. So something in the well, the porosity or permeability etc is reduced to a level where the well is no longer viable.

You should look at the properties along the well to see what happens when you change from poro-1 to poro-2.
