History Of Production Of Salt Creek Oil Field, Wyoming

THE Salt Creek oil field in Natrona County, Wyo., is the largest pool that has been found in the Rocky Mountain region and one of the largest in the United States. Many features of its production records are of peculiar interest, because of the unusual slowness with which it has been developed. This paper is published by the permission of the Midwest Refining Co., whose records have been freely drawn upon. Many mem¬bers of the Midwest organization have assisted in the collection of the material, but Messrs. F. E. Wood and L. E. Smith have been particularly helpful. The Salt Creek oil field is situated on a great dome with a closure of about 1500 ft., which rises at the northern end of a long anticline extending north-northwest by south-southeast for fully 25 miles. The productive area includes parts of townships 39 and 40 north and ranges 78 and 79 west of the sixth principal meridian. The Teapot oil field occupies a minor dome at about the center of the same anticline and adjoins the Salt Creek oil field on the southeast. The Teapot Naval Reserve includes the Teapot Dome and about 760 acres of the Salt Creek dome. In this paper, the Salt Creek oil field will be considered as' including all of the dome, except that part which lies within the Teapot Naval Reserve and the area west of the dome where oil is produced from shale crevices.
