Physics-Based Forward Modeling of Multistage Hydraulic Fracturing in Unconventional Plays (original) (raw)

This dissertation proposes a workflow for modeling of multistage hydraulic fracturing stimulation in unconventional formations. Based on the field case of a horizontal well targeted lower Wolfcamp formation in Midland Basin, this study identifies main gaps of publicly available data and provides estimations for critically important inputs: elastic properties, horizontal stress anisotropy, and pressure dependent leakoff. Breakdown and shut-in pressure are used to constrain horizontal stress anisotropy to a narrow range of 7.6-11.0% and avoid misleading published data for the Midland Basin. The developed model shows that oilfield operators can significantly, up to two times, reduce the size vii
