Cooperative well report: Maxus exploration Company Carl Ellis E-3 well, Ochiltree County, Texas. Topical report, January 1992-March 1993
Maxus Exploration drilled the Carl Ellis E-3 well in the Ellis Ranch Field, Ochiltree County, Texas in December 1991. The GRI cooperative research program on this well included coring, logging, stress testing, pre-fracture well testing, a mini-frac, post-fracture production data analysis, a fracture treatment, and a post-fracture well test. The well was completed in the Cleveland formation at 6,929-7,008 feet. After a ballout treatment, the well flowed 32 Mscf/day. Results of the pre-fracture pressure buildup test indicate a permeability-thickness product of 1.45 md-ft, a skin factor of -0.05, and a reservoir pressure of 1900 psi. The well was fracture treated with 70,000 gallons of a 40 lb/1000 gallon linear gel and 185,000 pounds of 20/40 sand. The initial post-fracture flow rate was approximately 500 Mscf/day. Post-fracture analysis with TRIFRAC indicated that the propped fracture height at the wellbore was 330 feet and the propped fracture length was 93 feet.
