Paper: Remedial Control of Injection Water

Effective waterflooding requires that injected water be condifed to and moved through the zones of permeability containing the remaining oil in place after primary production. The injection waters available for waterflooding are becoming more and more limited; therefore, this supply must be more efficiently utilized through confinement to the zones containing the secondary oil-in-place. Problems which are most common to water injection wells are those effecting confinement of injection water; i.e., channeling up or down out of zone, channeling through existing water stringers, or excessively high permeability zones, and simply going out bottom. Several different materials and methods are being used in efforts to control these water injection problems
