With the aim of elucidating hydrocarbon accumulation patterns and determining favorable exploration targets in the Hongde and Yanwu study areas, systematic research was carried out in this study. On the basis of prior research results, multiple datasets including structural features, fault systems, paleogeomorphic cond...

Deep coal seams are the key successor area for large-scale development of coalbed methane in China. However, deep coal reservoirs are characterized by “three highs and two lows”, and conventional hydraulic fracturing and foam fracturing are prone to water-sensitivity damage and poor adaptability, restricting efficient...

In the Shenfu block, deep methane reservoirs from coal seams at depths of 2000-3000 m face challenges such as high water consumption during conventional hydrofracturing, elevated treatment costs for the resulting fluids, and limited effectiveness in modifying the fracture network. CO2 foam fracturing, as a transformati...
