Hydraulic Fracture Design Evolution: Recent Advances in Proppant Transport Understanding | Amit SinghApr 1, 2022
Effective and economic proppant placement in hydraulically created fractures has been one of the key objectives of hydraulic fracture stimulation. Many different proppants, fracture fluids, and proppant placement methodologies have been historically used to achieve desired proppant conductivity and conductive surface area. Understanding the proppant transport mechanism has played a key role in increasing productivity at a low cost.With hydraulic fracture design evolution and increased activity, especially in unconventional resources, it is critical to consider proppant transport behavior in realistic fracture features such as lateral and vertical tortuosity, variable width, leak-off, and fluid dynamics replicating upward fracture growth.Distinguished Lecturer Amit Singh shares recent advances in understanding proppant transport from advanced laboratory and field studies. He covers how these novel learnings and important design considerations should be applied to optimize a “reservoir-centric hydraulic fracture design.” He also highlights the opportunity and need to optimize proppant and fracture fluid properties along with injection sequence for effective and economic proppant placement thereby achieving well stimulation goals.This presentation is from the Distinguished Lecturer 2021-22 season.
