[Help] Error when run ECLIPSE model?

[hoangbh86]

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

It means that your model could not control well by Oil rate (model rate much lower than observed rate) , then it changed to control BHFP. Check your input data well production history, units,...

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.
