Cleats are natural opening-mode fractures in coal beds. They account for most of the
permeability and much of the porosity of coalbed gas reservoirs and can have a significant …

Fractures are the main migration pathways for Coalbed Methane (CBM) in coals, which
dominate the permeability of coal reservoirs. One significant anisotropic characteristic of …

Heterogeneity in cleats and pore size distribution within coal macrolithotypes (bright, semi-
bright, semi-dull, and dull coals, determined from the overall relative luster and percentage …

Cleat in coal influences the occurrence, migration, and production of coalbed methane.
Therefore, research on the cleat can provide some important information for coalbed …

Cleats and fractures in Pennsylvanian coals in southwestern Indiana were described,
statistically analyzed, and subsequently interpreted in terms of their origin, relation to …

According to one embodiment, a system for accessing a subterranean zone from the surface
includes a well bore extending from the surface to the subterranean zone, and a well bore …

Gas flow in coal seam consists of laminar flow through coal cleat and diffusion through pores
of coal matrix. Previous studies on the prediction of CBM production mostly focused on the …

A field investigation into the development of cleat and other fractures within Permian coal
measures was undertaken in the Bowen Basin of eastern Queensland, Australia to provide …

A method for underground treatment of subsurface materials comprises providing an
injection pattern and a recovery pattern, the injection pattern and the recovery pattern …

A method and system for surface production of gas from a subterranean zone includes
