Hydraulic Fracturing and Rock Mechanics

This open access book is the first to consider the effect of non-uniform fluid pressure in hydraulic fractures. The book covers the key topics in the process of hydraulic fracture nucleation, growth, interaction and fracture network formation. Laboratory experiments and theoretical modeling are combined to elucidate the formation mechanism of complex fracture networks. This book is suitable for master's/Ph.D. students, scientists and engineers majoring in rock mechanics and petroleum engineering who need to use a more reliable model to predict fracture behavior.

Discusses the effect of non-uniform fluid pressure on hydraulic fracture growth Includes the static fatigue of fluid pressure on fracture initiation Offers in-depth theoretical deduction of hydraulic fracture model This book is open access, which means that you have free and unlimited access
