Study on Postfrac Softening Mechanism of Deep Marine Shale Reservoir in South Sichuan Basin
Geofluids, Volume 2023, Issue 1, 2023., 2023 Shale softening is an important factor affecting fracturing effect. Through the Brinell hardness measurement of deep marine shale reservoir in South Sichuan Basin, the softening mechanism of shale after fracturing is explored. Through laboratory test, the key parameters of shale Brinell hardness measurement are proposed as follows: indenter size 5 mm ...

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 ...
