Abstract

Simulation of complex fracture patterns in porous media can help understand and improve hydraulic fracturing processes, with potential for significant impact on enhancing oil and gas recovery. In this paper, a fully coupled hydraulic fracture propagation simulation method employing a hybrid finite e...
