Objectives and Significance

The majority of Mississippian production in Kansas occurs at or near the top of the Mississippian section just below the regional sub-Pennsylvanian unconformity. These reservoirs are a major source of Kansas oil production and account for approximately 43% (21 million barrels in 1994) of total annual production (Carr et a]., 1995a). Cumulative production from Mississippian reservoirs in Kansas exceeds 1 billion barrels. Many of these reservoirs and production units are operated by small independent producers. Extremely high water cuts and low recovery factors place continued operations at or near their economic limits.

This project addresses producibility problems in the numerous Kansas fields such as the Schaben field in Ness County that produce from Meramecian and Osagian dolomites beneath the subPennsylvanian unconformity. Producibility problems in these reservoirs include inadequate reservoir characterization, drilling and completion design problems, and non-optimal primary recovery. Tools and techniques will facilitate integrated, multi-disciplinary reservoir characterization. Application of cost-effective reservoir description and management strategies can significantly extend the economic life of these mature peritidal carbonate fields and recover significant incremental reserves. Equally important is innovative dissemination of the data, methodologies, and results to foster wider application of demonstrated technologies by the numerous operators of similar fields throughout the northern Mid-continent and US.
