Growth model for large branched three-dimensional hydraulic crack system in gas or oil shale

Recent analysis of gas outflow histories at wellheads shows that the hydraulic crack spacing must be of the order of 0.1 m (rather than 1 m or 10 m). Consequently, the existing models, limited to one or several cracks, are unrealistic. The reality is 10(5)–10(6) almost vertical hydraulic cracks per...
