Multiple analysis methods were performed on each well test result to ensure the validity of the constraints placed on the measurements.
Borehole image interpretation followed a number of basic mechanics principles described in AER/AGS Report 97 (Shen et al., 2018). All of the collected data compiled during this study are presented in this dataset.
Minimum horizontal stress and formation pore pressure are estimated from the wellbore fluid pressures recorded during the transient well tests. The recorded pressure history is analyzed using different plotting techniques to identify different phases of wellbore fluid flow. Fracture closure pressures and formation pore pressures are constrained with uncertainties determined from discrepancies between results from different plotting techniques. Figures of the results from various plotting techniques and a detailed description of the validity of these methods are given in AER/AGS Report 97 (Shen et al., 2018).
Stress orientations were determined by examination of collected borehole images. Details on the stress orientation measurements from borehole images can be found AER/AGS Report 97 (Shen et al., 2018).
Vertical stress was evaluated from the density logs extracted from nearby well bores.
