Paper: Identification of Candidates for Massive Hydraulic Fracture Treatments in The Spraberry Trend

The first hydraulic fracture treatments in the Sprabeny Trend consisted of 1500 gallons of refined oil carrying l/4 lb per gallon of sand. Since then, the average size of hydraulic fracture treatments has increased significantly to 180,000 gal of fluid and 432,000 lb of sand. The indication from a detailed characterization of the reservoir suggests that in certain cases an increase to over 900,000 lb of sand may be justified to maximize rate of return on investment. This should be combined with limited interval perforating and forced closure to ensure successful execution. Justification for these recommendations will be provided with an integration of the reservoir characterization and 3-D hydraulic fracture simulators.
