General Field Information

Produces Oil: Yes Produces Gas: Yes
Exploration Method: Core drilling to the stone corral. The cross section shows a less pronounced amount of dip over the structure on the stone corral than on the lower formations.
Drilling Casing Practices: The Simpson and Arbuckle production is from both perforated pipe and open hole completions. Acidization was used to enhance the Arbuckle production.

Oil & Gas Production Information
Produces Oil: Yes

Producing Formation:


SIMPSON
(Simpson Group)
Depth Top: 4402 feet
Formation Lithology: The Simpson sandstones consist of fine to medium, subrounded quartz grains. Some of the beds are slightly silty.
Trap Type: The Simpson sandstones, as well as the Viola and part of the Mississippian formations, have been truncated around a small anticline by the pre-Pennsylvanian uplift. The oil of the Simpson is believed to be indigenous. It is trapped at the unconformable contact with overlying Pennsylvanian beds.

Producing Formation:


ARBUCKLE
(Arbuckle Group)
Formation Lithology: The Arbuckle formation is a fine to medium, dark gray, sucrosic dolomite. Some of the upper beds contain silt and abundant gray cherts.
Trap Type: The Arbuckle oil is found in the porous and permeable layers situated over the anticline. It is believed that the thin layer of lower Simpson shale trapped any oil that might have migrated through fractures developed during the formation of this tight fold.
