Title: West Edmond Oil Field, Central Oklahoma

Author(s): D. A. McGee (2), H. D. Jenkins (3)

Abstract:

The West Edmond oil field of central Oklahoma, discovered April 5, 1943, had produced more than 32 million barrels of oil from 704 wells, through December 31, 1945. The field produced and ran 2,597,624 barrels of oil in November, 1945. Fifteen new wells were completed during the month of December. On January 1, 1946, there were thirty drilling wells in the field. Through December 31, 1945, an estimated 46,000,000 MCF of gas had also been produced. Seventeen of the 704 wells are producing oil from the "Bartlesville" sand of lower Pennsylvanian age; 687 wells are producing oil from the Hunton limestone of Siluro-Devonian age. The field embraces an area of 30,000 proved acres with 1,500 to 2,000 semi-proved acres.

The field is located on the northeastern rim of the Anadarko basin of western Oklahoma. The local structure is monoclinal, dipping west into the basin at approximately 125 feet to the mile. Oil production in the Hunton group is the result of a wedge-out of the upper or Bois d'Arc limestone member against the Nemaha ridge on the east and a regional wedge-out of the Hunton group on the north. Oil accumulation generally is in coarsely crystalline limestone. The Bois d'Arc limestone reaches a maximum known thickness of 140 feet on the west side of the field and wedges out completely at the east, thus delineating the eastern limits of production. There is some minor oil production in the field from the lower or Chimneyhill limestone member of the Hunton limestone where porosity is develope locally. In one small area in the northeastern part of the pool, oil is produced from the middle or Haragan-Henryhouse due to a local development of porosity.
