There have been significant advances in the application and development of hydraulic fracturing technology in the past several years. This paper presents an overview of some of these advances to provide the reader with a perspective of the current fracturing state of the art. The discussion addresses economic design considerations; fracturing material behavior (propping agents, fracture conductivity, fluid loss, fluid rheology and proppant transport); field acquired fracture design, diagnostic and analysis technology (in-situ stresses and stress profiling, downhole fracturing pressure and pressure decline analysis, real-time on-site monitoring and control, and fracture mapping); and three-dimensional fracture propagation simulation. A comprehensive bibliography is provided as a resource for in-depth perusal of each area by the interested reader.
