Particle transport in fractured geo-energy reservoirs considering the effect of fluid inertia and turbulent flow: A review

Abstract

Particle-fluid two-phase flows in rock fractures and fracture networks play a pivotal role in determining the efficiency and effectiveness of hydraulic fracturing operations, a vital component in unconventional oil and gas extraction. Central to this phenomenon is the transport of proppants, tiny solid particles injected into the fractures to prevent them from closing once the injection is stopped. However, effective transport and deposition of proppant is critical in keeping fracture pathways open, especially in low-permeability reservoirs. This review explores, then quantifies, the important role of fluid inertia and turbulent flows in governing proppant transport. While traditional models..
