Evaluation of Present Tectonic Stress Field and Permeability of Coalbed Methane Reservoirs by Inversion of Logging Data From Longtan Formation, Dahebian Block

Energy Science &Engineering, EarlyView.
ABSTRACT The permeability of coal reservoirs is predominantly controlled by the present tectonic stress field. This study systematically integrates macro‐ and micro‐scale analytical methods to investigate the controlling mechanisms of tectonic stress on pore‐fracture characteristics and permeability in the Longtan Formation coal reservoirs.
