ABSTRACT

Economic production from tight shale formations entails increasing the surface area in contact with the reservoir via hydraulic fracturing. Important to the design of efficient hydraulic fractures is knowledge of the orientation and magnitude of principal stresses and geomechanical rock properties. Using the results of seismic AVA (Amplitude Variation with Angle) inversion calibrated to geomechanical measurements on cores, a 3D MEM (Mechanical Earth Model) is built for an area in the Horn River Basin. The variation in principal stresses over the area is evaluated using the Finite Element Method. Computed stresses are seen to be consistent with variability in production over the area and show stress rotations near faults in agreement with microseismic data.
