Height Propagation Law and Controlling Strategies of Acid Fractures in Carbonate Gas Reservoirs With Bottom Water Layer Under Different Stress Profiles

Geofluids, Volume 2025, Issue 1, 2025.
Acid fracturing is currently employed to develop the carbonate gas reservoir in the second section of the Dengying Formation at the Anyue Gas Field, Sichuan Basin. However, improper acid‐fracturing operational parameters pose a risk of fracture communication with the bottom water layer, leading to increased water production and a significant decline in

An Analytical Formulation for Correcting the Relative Permeability of Gas‐Water Flow in Propped Fractures Considering the Effect of Brinkman Flow

Water Resources Research, Volume 60, Issue 11, November 2024.
Abstract Gas‐water flow in propped fractures can be commonly observed in various practical applications, including hydrocarbon development, geothermal exploitation, contaminant transport, and geological carbon storage. The fluid flow in a propped fracture can be regarded as Darcy type if only the resistance from the propping materials (e.g., cement in ...

An Innovative Production Prediction Model for Fractured Horizontal Wells in Low‐Permeability Gas Reservoirs Accounting for Proppant Embedment

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
This study focuses on addressing the challenge of accurately calculating the production caused by stress sensitivity and proppant embedment during actual production in low‐permeability gas reservoirs. To achieve this, a stress sensitivity model in the matrix zone and a proppant embedding model in the fracture area are established.
