sorry, but resting wells sounds too "renewable."
imo, a better explaination would be that in this highly heterogeneous reservoir, gravity segregation and imbibition account for the benifit of a shut-in.
aramco has claimed that their water displacement in ghawar is gravity stable. gravity stable displacement will result in a very good recovery of ooip, on the order of 65%. gravity is good, gravity is always there. gravity seems to be all but ignored in petroleum engineering lore.
how to fit this on a bumper sticker ?
I have a post on "coning" and the other problems of trying to speed up production, but it is a little ways off yet.
coning is a wellbore problem, i am talking about the displacement rate for the reservoir.
