Hydraulic Fracture Model Comparison Study

Résumé du livre

This study is a comparison of hydraulic fracture models run using test data from the GRI Staged-Field Experiment #3 (SFE-3). Models compared include: (1) PKN and GDK constant-height versions; (2) 3-layer pseudo-3-D models; and (3) 5-layer 3-D or pseudo-3-D models. Model calculations were provided by several consulting companies, oil producing companies, service companies, and academia. Modelers were given the measured stress and material property data obtained at SFE-3 stimulations. Companies were allowed to run any or all of the three cases (constant height, 3 layer, or 5 layer) using their own models or commercial models they had purchased. Included with the results are brief discussions of each model. This paper documents the differences in length, height, width, pressure, and efficiency predicted by the various models for each of the three cases.
