title: State of in-situ stress and implications for fault slip potential in the Montney Play, Western Canada

description: These are datasets used for the paper "State of in-situ stress and implications for fault slip potential in the Montney Play, Western Canada".

The following three Excel files are the pore pressure, the DFIT closure pressure, and sonic logging data location information. 1. "Pore pressure measurement.xlsx", the Montney Formation pore pressure measurement data.2. "DFIT closure pressure.xlsx", the Montney Formation DFIT closure pressure data.3. "Data points for Montney Formation areal in-situ stress calculations and maps.xlsx", well location data points, including the estimated vertical stress and elastic properties at the point location. 

The UWIs for the data points in the above three files are not included but are available upon request.

Grid values of horizontal strain correction factors are included in the following four files. "Epsilon_H_Max_LB.txt", "Epsilon_H_Max_UB.txt", "Epsilon_h_min_LB.txt", "Epsilon_h_min_UB.txt".

The fields in each file: Longitude, Latitude, and Epsilon (mm/m).LB = the lower bound of the maximum horizontal stress case;UB = the upper bound of the maximum horizontal stress case;H_Max = along the maximum horizontal stress direction; h_min = along the minimum horizontal stress direction.

The grid values of pressure and in-situ stresses for respectively the Commingled Montney, Upper Mopntney, Middle & Lower Montney are compiled in three zip files: "Grid value of pressure and stress_Montney_Commingled.zip", "Grid value of pressure and stress_Montney_U.zip", and "Grid value of pressure and stress_Montney_ML.zip".
