Characterization of Proppant Flowback in Hydraulic Fracturing Rough Fractures
Energy Science & EngineeringIn the process of fracturing, proppant flowback is unavoidable, and excessive proppant flowback will cause sand plugging in the wellbore, change the morphology of proppant fractures, reduce the effective flow‐conducting capacity of fractures, weaken the ...

Modeling of Two-Phase Flow in Rough-Walled Fracture Using Level Set Method [PDF]
Geofluids, 2017 To describe accurately the flow characteristic of fracture scale displacements of immiscible fluids, an incompressible two-phase (crude oil and water) flow model incorporating interfacial forces and nonzero contact angles is developed.

A Modified Cubic Law for Rough-Walled Marble Fracture by Embedding Peak Density
Advances in Civil Engineering, 2020 The property of water flow through a single rock fracture is the base of describing the seepage characteristics of jointed rock mass. Five artificial tensile fractures of coarse-grained cylinder marble samples were made at about the midpoint of the long ...

A Novel Approach to Investigating Transport of Lost Circulation Materials in Rough Fracture
Energies, 2018 The drilling fluid loss or lost circulation via fractures is one of the critical engineering problems in the development of deep oil and gas resources. The conventional treatment is to introduce granular lost circulation material (LCM) into the drilling ...

Hydrothermal coupling in a self-affine rough fracture [PDF]
Physical Review E, 2010 The influence of the multiscale fracture roughness on the heat exchange when a cold fluid enters a fractured hot solid is studied numerically on the basis of the Stokes equation and in the limit of both hydrolubrication and thermolubrication. The geometrical complexity of the fracture aperture is modeled by small self-affine perturbations added to a ...

Fractal model of shear-induced rough fracture flow by cross-scale description of its geometry
矿业科学学报, 2023 The Beishan area in Gansu province is the main pre-selected site for deep geological disposal of high-level radioactive waste, it therefore bears implications for the study of fracture seepage characteristics of granite caused by shear failure.

Numerical and Analytical Study of Fluid Flow and Thermal Transfer in a Rough Fracture
Geofluids, 2022 The surface morphology of rough fractures significantly affects the fluid flow and heat transfer characteristics in the fractures. A thermal-flow coupling model with specific geometric fractures was established to investigate the influence of surface ...
