Apache used ResFrac to tightly constrain their Midland Basin pad models. Apache is a leader in gathering and interpreting advanced diagnostics. In SPE-204172, Shahri et al., describe the detailed calibrations possible with ResFrac and cross-well engineered fiber from Silixa. ResFrac outputs the full stress and strain tensors at any location in the model. These data can be used to directly compare to the strain rate data gathered from cross-well fiber-optic monitoring.
