... simulator with the classical methods - static PD region scheme, dynamic PD region scheme, and adaptive mesh refinement scheme. PD equations are solved using a refined mesh close to the fracture, whereas FE/FV equations are solved using a progressively coarser mesh away from the fracture. As the fracture...

...-planar fractures with a narrow curvature. In this paper, a 3D multi-phase particle-in-cell (MP-PIC) model was applied to simulate the proppant transport in curved fractures. We built a 180-m-long and 30-m-high fracture with a curving angle of 45°. In the base case, the proppants of 100 mesh size...

... behaviors in the field scale. The simulation of proppant transport behaviors in both symmetrical and asymmetrical fracture geometries with different proppant sizes can promote our understanding of proppant transport behaviors and help us to improve fracturing design. fracturing fluid mesh proppant...

... on experimental work. The size of proppants is one of the key determining parameters when calculating uplift and settling velocity. They travel farther into the fracture, since they settle slower with less gravitational impact. Fine mesh is highly recommended to effectively deliver proppant to the horizontal...

... temporal and spatial finite-difference formulation and permits overcoming computational limitations related to the nonlocal space and time derivatives characteristic of the partial differential equation to be solved. The flexible mesh allows for significant improvements in execution runtime, while...

..., the mineralogy, porosity, and pore size distribution of the sample were obtained. Furthermore, visualization of the resulting models revealed the full detail of the shale rock geometry, which was later meshed to a tetrahedron volume mesh for any further transport phenomena modeling and simulation studies...
