Theoretical Analysis of Proppant Embedment and Fracture Conductivity in Fractured Reservoir [PDF]
Abstract Proppant embedment mainly accounts for diminishing fracture aperture and conductivity. The conductivity decrease could greatly restrict fluid flow, thereby affecting the well performance. In this paper, new mathematical models are derived to calculate the proppant embedment and fracture conductivity after hydraulic fracturing ...

Influence of proppant embedment on fracture conductivity
Abstract Using the national invention patent equipment, the proppant embedment experiment was carried out on the formation coal seam. The effects of proppant embedment on the conductivity of cracks under different proppant types, different proppant particle sizes, different sanding concentrations and different closing pressures were ...

Effect of proppant distribution in hydraulic fractures on coalbed methane extraction
Fracturing with proppants is often used to improve the permeability of coalbed methane (CBM) reservoir. The fracture is easy to close under the closure stress and the proppant distribution in fractures greatly influences the extraction efficiency of CBM.

Experimental Study on Fracturing Fracture Deformation Mechanism of Shale Reservoir
After large-scale sand fracturing of horizontal wells in shale gas reservoir, fracturing fractures will deform in the production process. However, fracture deformation will lead to the decrease in fracture conductivity and then cause the decrease of gas ...

Numerical Modeling of the Conductivity of the Particle Monolayer with Reduced Size
Fractures filled with a proppant monolayer play an important role in the hydraulic fracture network. Predicting the conductivity of these fractures is the basis of fracture network optimization. However, little attention has been paid to the conductivity
