HYDROCARBON PRODUCTION BY FLUIDICALLY ISOLATING VERTICAL REGIONS OF FORMATIONS

摘要

Techniques of hydrocarbon production by fluidically isolating vertical regions of formation are described. A subterranean zone entrapping hydrocarbons includes multiple vertically arranged regions. Each region has a respective permeability for fluid flow. An open production well to produce the hydrocarbons and an open injection well to aid hydrocarbon production are formed in the subterranean zone through the multiple vertically arranged regions. At each of the production well and the injection well, the vertically arranged regions are fluidically isolated from each other. Injection fluid injected through the injection well into a fluidically isolated region is substantially confined to flow in the fluidically isolated region. A flow of the injection fluid into each fluidically isolated region is controlled to control a recovery of hydrocarbons trapped in each fluidically isolated region.
