A Lubrication‐Based Solver for Shear‐Thinning Flow in Rough Fractures

Water Resources Research, Volume 58, Issue 8, August 2022., 2022
Abstract The depth‐averaged (2D) lubrication theory is often adopted to simulate Newtonian flow in rough fractures. This approach, which is computationally much less expensive than using 3D CFD solvers, allows addressing large ensembles of stochastic fracture realizations.

Review: Induced Seismicity During Geoenergy Development—A Hydromechanical Perspective

Journal of Geophysical Research: Solid Earth, Volume 127, Issue 3, March 2022., 2022
Abstract The basic triggering mechanism underlying induced seismicity traces back to the mid‐1960s that relied on the process of pore‐fluid pressure diffusion. The last decade has experienced a renaissance of induced seismicity research and data proliferation.

Coupled Poroelastic Modeling of Hydraulic Fracturing‐Induced Seismicity: Implications for Understanding the Post Shut‐In ML 2.9 Earthquake at the Preston New Road, UK

Journal of Geophysical Research: Solid Earth, Volume 127, Issue 3, March 2022., 2022
Abstract Post‐injection seismicity associated with hydraulic stimulation has posed great challenges to hydraulic fracturing operations. This work aims to identify the causal mechanism of the post shut‐in ML 2.9 earthquake in August 2019 at the Preston New Road, UK, amongst three plausible mechanisms, that is, the post shut‐in pore pressure diffusion ...

Stability Evaluation of Proppant in Fractures of Gas Storage in Yulin Gas Field

Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
In nearly a hundred years of construction, underground gas storage has become the main natural gas storage and peak regulation means in the world. For the gas storage, the large production and high flow rate of the gas well in the actual production process will cause the backflow of proppant filled in the supporting fracture, which will bring great ...

Study on the Deformation and Stability of Proppant Column in High‐Conductivity Channel Fracturing

Geofluids, Volume 2022, Issue 1, 2022., 2022
The nonlinear constitutive model of the proppant column was established through laboratory experiments on the stability of the proppant column. Based on reservoir geomechanics and the finite element method, a fracture‐proppant column interaction model was established for high‐conductivity channel fracturing.

[Retracted] High‐Temperature‐Resistant, Clean, and Environmental‐Friendly Fracturing Fluid System and Performance Evaluation of Tight Sandstone

Journal of Environmental and Public Health, Volume 2022, Issue 1, 2022., 2022
Hydraulic fracturing, as an oil‐water well stimulation and injection technology, is particularly important in the production and stimulation of low‐permeability oil and gas fields, and the performance of the fracturing fluid directly affects the success of the fracturing operation.
