Hydraulic Fracture Design Evolution: Recent Advances in Proppant Transport Understanding Amit Singh, Chevron
Effective and economic proppant placement in hydraulically created fractures has been one of 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 in reservoir. The understanding of the proppant transport mechanism has played a key role in this design evolution to achieve the goal of increased productivity at low cost.
The traditional proppant transport laboratory study with standard slot flow test captured basic flow characteristics and shaped historical hydraulic fracture design practices. The standard slot flow test with parallel plates represented only a simplified planar fracture with homogeneous constant width and confined height, and thus, was incapable of capturing proppant transport phenomena impacted by realistic fracture features. With hydraulic fracture design evolution and increased activity specially in unconventional resources (UCR), it is critical to consider proppant transport behavior in realistic fracture features including lateral and vertical tortuosity, variable width, leak-off, fluid dynamics replicating upward fracture growth, etc.
This presentation will share the recent advances in understanding of proppant transport from advanced laboratory and field studies; and how these novel learnings and important design considerations should be applied to optimize a "reservoir-centric hydraulic fracture design". It will also highlight opportunity and need to optimize both proppant and fracture fluid properties along with injection sequence for effective and economic proppant placement thereby achieving well stimulation goals.
