Production Forecasting of Unruly Geoenergy Extraction Wells Using Gaussian Decline Curve Analysis
Geofluids, Volume 2023, Issue 1, 2023., 2023 Fast and rigorous well performance evaluation is made possible by new solutions of the pressure diffusion equation. The derived Gaussian pressure transient (GPT) solutions can be practically formulated as a decline curve analysis (DCA) equation for history matching of historic well rates to then forecast the future well performance and estimate the ...

Optimization of Carbon Dioxide Foam Fracturing Technology for Shale Gas Reservoir
Geofluids, Volume 2023, Issue 1, 2023., 2023 Major shale gas exploration and development fields are located in the Sichuan basin. It requires huge water sources for shale gas fracking, but the well sites are mostly in the hills, which limits the industrialization of shale gas development. CO2 foam fluids can meet the requirements of fracking fluids and relieve water stress.

The Effect of Slickwater on Shale Properties and Main Influencing Factors in Hydraulic Fracturing
Geofluids, Volume 2023, Issue 1, 2023., 2023 As shale gas reservoirs have low porosity and low permeability, hydraulic fracturing is a necessary means for industrial exploitation of shale gas. In this study, aiming at the problem of reservoir damage in the process of hydraulic fracturing of shale gas reservoir, a physical simulation method of slickwater fracturing fluid flow in shale core has ...

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.

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.
