The Southwest Velma field is located in Secs. 34 and 35, T. 1 S., R. 5 W., and Secs. 2 and 3, T. 2 S., R. 5 W., Stephens County, Oklahoma. The productive area is about 2 miles long in a northwest-southwest direction and ¾ mile wide. It produces from five sandstone members of the Springer formation.
The structure is a faulted anticline with the production on the southwest flank. Two faults form the trap, one a major fault along the northeast side of producing area, and an auxiliary fault along the southeast end of the producing area. A third fault within the producing area apparently creates a separation of sources of supply in each sand member.
The structure has been involved in three distinct periods of movement in Pennsylvanian time and is the result of compressive forces acting upon the rocks of the area from the southwest and the northeast. The incompetent shales underlying and between the Springer sandstones yielded to pressure by upward buckling.
The field covers approximately 530 acres and has 55 producing wells. Daily production for the field in August 1953 exceeded 4,000 barrels; total production is over 1,115,000 barrels since the discovery well was drilled in July 1951. Development is continuing to the northwest.
