Comparison of hydraulic fracture design methods to observed field results
The fracture models developed by Khristianovich and Zheltov, and Perkins, Kern, and Nordgren are compared to field, fracturing treatment data. It was found that the Khristianovich-Zheltov model agrees with the field data as adequately as the Perkins-Kern-Nordgren model, and that both models need to take changing instantaneous shut in pressure into account. A method for on-the-job fluid loss coefficient measurement is developed based on measurements of increasing instantaneous shut in pressure. Examples illustrating the fluid loss coefficient measurement method are discussed. Finally, examples are presented which show the excellent agreement between field data and production estimates based on Khristianovich-Zheltov fracture parameters.
