Fracture propagation model accounting for intersection among hydraulic fractures and natural fractures in three-dimensional space

Meitan xuebao
Due to development of a large number of natural fractures in unconventional gas and oil reservoirs, the fracture expansion patterns during hydraulic fracturing are complicated. It is crucial to clarify the intersecting and expanding mechanical mechanisms
