... ABSTRACT: In this research, a numerical modeling approach, combining the Discrete Element Method (DEM) with lattice Boltzmann (LB) method, was adopted to investigate the potential effects of mixed proppant sizes on fracture conductivity. DEM was used to simulate effective stress increase...

The results indicate that proppant-absent...

... case. Aiming at this problem, this paper investigates impacts of acid-rock contact time, acid etched fracture creep, proppant size and concentration on the long-term conductivity. The study shows that the acid propped fracture retained enough conductivity under high closure stress. Gelled acid fracture...

... Abstract Proppant additives play an essential role in hydraulic fracturing as they provide support, which retains the fracture opening after the pumping is shut off. From a production point of view, a larger proppant size provides better permeability, while, at the same time, gravitational...
