[1][2] The field produces from several strata in the Big Muddy Anticline, which covers about 9,000 acres (3,600 ha).
The Shannon oil stratum lies at an average depth of 1100 feet in a 30-foot (9.1 m) layer of sand.
The Lakota and Stray sands were exploited in later years, with 1,367,316 barrels produced by 1949 from eleven wells.
The refinery and another built by Standard Oil in Glenrock and others in Casper were connected to the field by pipelines.
Link Energy's production has focused on gasification of strata to produce mainly gas from the field, using a coking process.
