Abstract
Abstract Multiple gamma emitting tracers and post fracture spectral gamma ray logs were used to optimize production and improve the completion designs of 150 gas wells in the southwest Kansas region of the Hugoton Field. The information from the tracers and logs has revealed unstimulated pay zones and has been the impetus for completion modifications, yielding substantial gains in production. Through the use of limited stress barriers and permeability variations, perforation schemes have been successfully modified to improve fracture containment and proppant placement over the 200 ft Chase Group intervals. Previously these intervals were treated with multiple individual zone treatments.
