Paper: Cedar Lake Southeast Field San Andres Reservoir Behavior Under Water Flood

A water injection program was commenced in the San Andres reservoir of the Cedar Lake Southeast Field of Dawson County, Texas in May 1962. The Cedar Lake Southeast Field was unitized with the unit including virtually all of the San Andres reservoir that could reasonably be expected to be productive of oil or gas. The Cedar Lake Southeast San Andres reservoir is small in volume as compared to the many large reservoirs of the same age in the Permian Basin provenance. The size of this reservoir along with principles of its development and operation under water injection offer a good opportunity to observe the hydraulic behavior of fluids of San Andres age when subjected to complete reservoir water flood practices of production. Response to water flood operations in this field have been excellent during the 21 months of its operation. Production from the reservoir during the past 8 months has been retained within the limits prescribed by statewide proration. The history of this reservoir and the operational practices that have aided its realization of an economic performance are presented.
