Research on the Multiscale Microscopic Pore Structure of a Coalbed Methane Reservoir

Energies
Coal rock pores are the space in which coalbed gas is stored and flows. Accurately characterizing the pore structure of coalbed gas is the foundation of coalbed gas reserve assessment and production forecasting.

Design and application of adaptive intelligent drainage and production process for high-water-production gas wells [PDF]

Youqicang pingjia yu kaifa
High-water-production gas wells experience significant wellbore pressure loss. During production, pressure decline can cause the liquid droplets in the wellbore to fall back and accumulate, forming slug flow.

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.

Inverse Design of Metal‐Organic Frameworks for CH4/N2 Separation Enabled by Coupled Machine Learning and Genetic Algorithms

Advanced Science, Volume 12, Issue 46, December 11, 2025.
A machine learning‐guided genetic algorithm is employed to explore metal‐organic frameworks (MOFs) for CH4/N2 separation. By combining predictive modeling with adaptive evolution, the approach identifies high‐selectivity candidates featuring fsc topologies and polycyclic ligands, offering an efficient route to discovering high‐performance separation ...

Equivalent Modeling and Simulation of Fracture Propagation in Deep Coalbed Methane

Energies
Deep coalbed methane (CBM) is challenging to develop due to considerable burial depth, high ground stress, and complex geological structures. However, modeling deep CBM in complex formations and setting reasonable simulation parameters to obtain reasonable results still needs exploration.
