Abstract
A method for simultaneous recovery of crude oil from multiple zones in a reservoir is disclosed wherein multiple wells, each in fluid communication with at least two hydrocarbon zones separated by an impermeable barrier, are used to produce oil in an enhanced recovery process. The end product from recovery in one zone is used to augment the recovery process in another zone.
