Understanding Vertical Fracture Growth in the Marcellus Shale using Advanced Microseismic Methods

ESG acquired, processed and analyzed microseismic data for a hydraulic fracture stimulation in the Marcellus Shale. Advanced analysis was performed to evaluate disparity in vertical growth behaviour between stages. Using Seismic Moment Tensor Inversion, ESG found that stages exhibiting vertical fracture growth appeared to activate moderately dipping joint sets and could be related to stress induced by a buckling anticline.
