General Field Information

Produces Oil: Yes Produces Gas: Yes
Exploration Method: Rhodes field was discovered as a result of a land test drilled by Barbara Oil Company. No exploration, such as subsurface, was involved even though the area, in general, was thought to be favorable for Mississippian production. Continental Oil Company drilled the Cavin 1 well in T33S-11W-29, SW SW NW, as a stratigraphic test on weak core drill nosing. This producer was designated originally as the Gerlane Field. Through subsequent drilling, the Rhodes and Gerlane fields were incorporated. The advent of improved hydraulic fracturing has been the main factor in the extensive and successful development of the Rhodes Field.
Drilling Casing Practices: Through the mid 1950s, the completion method was to set pipe through the entire pay zone and then to selectively perforate and sand fracture the porous intervals indicated on electric logs or cores. Some of the initial wells were completed from open hole.

DOUGLAS
(Douglas Group)
Depth Top: 3773 feet
Trap Type: The Douglas gas sand is a stratigraphic trap formed by the shaling out up dip of the sand. The sand pinches out down dip and is present only in the extreme northwest part of the field. A good water drive is thought to be present with the pay zone varying from 0 to 50 feet. The sand, where present, is described as being fine-grained to silty, shaly and micaceous.

MISSISSIPPIAN
(Mississippian System)
Depth Top: 4480 feet
Formation Lithology: The Mississippian reservoir rocks vary extremely over the field. In places, the reservoir is made up of cherty limestones and dolomitic limestone with abundant siliceous material. Other reservoir lithologies include the typical chat section composed of tripolitic chert and fresh grey banded chert interbedded with green waxy to hard shale. The chat section in general has a highly brecciated appearance.
Trap Type: The Mississippian pay is a typical stratigraphic trap formed by erratic lithologic variation and pinch out of porosity and chat section up-dip to the north. The surface of the Mississippian dips southward at approximately 50 feet per mile and is truncated by Pennsylvanian shales with only erratic instances of a conglomerate section being present at the base of the shales.

Oil & Gas Production Information
Produces Oil: Yes Produces Gas: Yes
Drive Mechanism: Oil is produced by solution gas drive although a few wells require pumping equipment. At the northern edge of the field a gas cap is thought to exist. Small amounts of water are produced erratically over the field but as yet no water drive has been encountered.
