These variable geomechanical logs and minimum stresses derived from surface drilling data are used to model the optimal asymmetric frac design and its resulting geometry. Fracture pressure analysis is done where the modeled surface-treating pressures are calibrated...

... fracture geometries using tempo-spatial extension of microseismic data. In the study area, ten horizontal wells were drilled and hydraulically fractured in multiple stages in the Muskwa, Otter Park, and Evie shale gas formations in 2013. The treatments were monitored by downhole microseismic measurements...

...? Figure 4c shows some results from large-block tests on Marcellus shale outcrops as part of a Shell funded program of research. Under a confining stress where the vertical stress is greatest (i.e. an extensional stress regime), the hydraulic fracture geometry was strongly affected by the layering...
