Abstract
Official abstract text for this publication.
Methods and systems are provided for selectively displacing water from a hydraulically continuous water zone in a porous geological formation. The target zone to be displaced is defined by a hydrodynamically maintained pressure differential, which has been shown to be capable of confining an expanding injected gas zone. One or more gas injection wells and water production wells are located within the zone. During pressurized gas injection within the zone, the gas displaces water downward within the confined zone such that water is selectively produced from the target zone and the injected gas zone is confined within the hydraulically continuous water zone.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for selectively displacing aqueous fluid from a hydraulically continuous aqueous fluid zone of a permeable geological formation, the method comprising: a) selecting a target region of the formation that is in pressure communication with a hydrocarbon reservoir; b) hydrodynamically adjusting aqueous fluid pressures within the hydraulically continuous aqueous fluid zone, so as to provide a horizontal fluid pressure differential within the hydraulica…
