... as the simulation platform, DPM as the base model, and compare the simulation data with settling velocity experiment data to draw conclusions. Three cases were run and tested including fracture fluid type, proppant size, and fracture orientations. Results show a good integration between experimental results...

... 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...
