... most likely geology. The higher signal gradient of Stages 15 to 20 suggests these stages generated greater complexity in the shale target. Compared to the longer and more planar fracture networks in the limestone, the shale stages showed shorter fracture lengths and more inter-stage interactions. Note...

... This question of how to translate microseismic datastreams into estimates of fracture effectiveness is a complicated one. We advocate an approach that seeks to characterize the deformation and the fracture network based on an agglomeration of microseismic events. For example, after inverting for...
