Pore Geometry and Its Influences on Methane Adsorption in Shale Gas Reservoirs: A Case Study of Longmaxi Shale in the Da’an Area, Chongqing, China

Journal of GeoEnergy, Volume 2026, Issue 1, 2026.
Understanding pore structure and methane sorption (MS) in shale gas reservoirs is critical for accurately estimating gas‐in‐place and prospective natural gas resources. The Longmaxi Shale, a leading formation for deep shale gas development in China, faces challenges in its economic production due to its strong spatial heterogeneity, complex pore ...

Methodologies for Gas Content Evaluation in Deep Coal/Shale Formations: Assessment, Improvement, and Comparison

Journal of GeoEnergy, Volume 2026, Issue 1, 2026.
Gas‐in‐place (GIP) content is a critical indicator for evaluating deep coal/shale resource potential, typically categorized into lost gas content, desorbed gas content, and residual gas content. The lost gas content cannot be directly quantified and requires specific methods for assessment.
