Title: Geologic description of the San Andres reservoir facies in the Mabee field

The Mabee field is located in Andrews and Martin counties, Texas, approximately 16 mi northwest of Midland in the Permian basin. Production is from the upper Permian San Andres dolomite at an average depth of 4700 ft. The San Andres/Grayburg formations are the most prolific oil-producing formations in the Permian basin, with total production over 10 billion bbl, and an estimated additional 3.8 billion bbl to be recovered by conventional secondary and tertiary methods. The Mabee field has produced over 90 MMBO by primary and secondary methods since its discovery in 1943. A tertiary CO{sub 2} flood will be implemented in 1992. An essential prerequisite to a successful CO{sub 2} project is a detailed reservoir description and facies analysis. Examination of over 5000 ft of core established six major facies in an overall shallowing-upward sequence. The cap rock consists of dense anhydritic dolomites of the supratidal and oncolite facies. Production primarily is from the underlying dolomitized subtidal and ooid facies. Sandstones interfinger with the ooid facies, but are tightly cemented and act as barriers to fluid migration. The lower-most open-marine facies is below the oil/water contact for the field. Reservoir characterization improves the planning and operation of an enhanced recoverymore » project.« less
