Hydraulic fracture treatment analysis and post-fracture evaluation. Enron Oil and Gas Company Sawyer 144a No. 5, Sawyer field (Middle Canyon Sands) Sutton County, Texas. Topical final report, November 29, 1990-April 10, 1992

The report provides analysis and evaluation of the fracturing of the ENRON Sawyer 144A Number 5 in the Middle Canyon sands. The pump-in/shut-in, minifrac and main fracture treating pressure responses have been matched using FRACPROR and the corresponding propped fracture geometry has been corraborated by history matching the production and bottomhole pressure responses with the FraPS (2-D, single phase) reservoir simulator, using the RESPROTM interface to FRACPROR. An additional evaluation of the long-term production history indicates consistency of the reservoir modeling. The good quality of the matches supports the predicted geometry from FRACPROR and indicates some potential for greater economic optimization of subsequent treatments. The analyzed treatment achieved an estimated propped fracture length of 247 feet with a proppant concentration sufficient to provide an infinite conductivity response.
