Paper presented at the SPE Hydraulic Fracturing Technology Conference and Exhibition, February 1–3, 2022
Paper Number: SPE-209150-MS
... Abstract Hydraulic fracturing creates rough fracture surfaces, instead of smooth ones, in subsurface formations. It is challenging to simulate the complex proppant transport phenomena in rough fractures due to the roughness effect as well as the complex nature of the coupled particle-fluid two...

...-surface characteristics (such as roughness and fractal dimensions) may greatly affect the proppant transport during hydraulic fracturing operation. Few researches have focused on investigating the proppant transport in vertical fracture with actual surface characteristics. As a continuation of our...

... and Young's Modulus with fracture conductivity. Increased fracture face surface roughness is also found to have an overall decrease in conductivity in propped fractures. The influential parameters are different for different shale plays. Some parameters are more important in one formation but less influential...

Paper Number: SPE-184852-MS
... is developed to simulate the stress-driven closure and the conductivity for fractures with rough surfaces. The model integrates elastoplastic deformation and deformation interaction, and can handle contact between heterogeneous surfaces. Computation is optimized and accelterated by employing an algorithm...

... regardingvalidation and simulation strategy. The model geometry is highly idealized ( i.e. , neglectingfracture tortuosity and expansion during water fracturing, surface roughness and fluid leakoff). The importance of this work lies in the fact that the model can resolve the interactions between fracturing fluid...

... on the rough fracture faces, and is independent of rock heterogeneities due to the small sample size." Moreover, almost one year ago, one wrote, "More asperities touch and deform as the closure stress increases. The channels become even shorter and fewer openings are left." Between these two extremes...

When two roughness parameters of each corresponding fracture surface are superposed, the fracture conductivity can be related to the statistical parameters of etching. In this paper we present experimental...
