RI 5448 Petroleum-Engineering Study Of Muskogee Oilfield, Muskogee County, Okla. ? Introduction And Summary

This report describes the geology and reviews the oil-production history of the Dutcher sands of Pennsylvania age in the Muskogee oilfield. The geology and production history are presented not alone as a review of the past behavior of the field but also to interpret the possibilities for future production of oil from semidepleted sands in this and similar areas. The Muskogee field, one of the oldest oil-producing areas in Oklahoma, yields paraffin-base oil of 40° API gravity -a gravity higher than that of most Oklahoma oils. Oil was discovered in the townsite of Muskogee in 1894 but was not produced in commercial quantities until 1904. A peak yearly rate of 1,340,000 barrels of oil was attained in 1910 (see table 1).
