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
