摘要

Wexpro Company drilled the Church Buttes Well No. 48 in May 1989 in SweetwaterCounty, Wyoming. Cores, logs, and cased hole in-situ stress tests were obtained in the Frontier formation to help in the detailed evaluation. The well was perforated in the Frontier at 12,163-12,196 feet. A mini-frac was performed along with a downhole microseismic diagnostic test. Wexpro fracture treated the well with 160,000 gallons of 65-quality CO2 foam and 263,000 pounds of 20/40 mesh intermediate strength proppant. History matching of the treatment data with FRACPRO resulted in a propped fracture length of 280 feet. Short-term post-fracture production indicated that a short, low conductivity fracture was apparently achieved.
