As with other reservoir types permeability is a key controlling factor for gas migration in
coalbed methane reservoirs. The absolute permeability of coal reservoirs changes …

Unconventional gas reservoirs, including coalbed methane (CBM), tight gas (TG) and shale
gas (SG), have become a significant source of hydrocarbon supply in North America, and …

The most common fallacy in the quest for the optimum stimulation treatment in shale plays
across the country is to treat them all just like the Barnett Shale. There is no doubt that the …

Permeability changes can be very large during depletion of coalbed methane wells: up to
100 times in the San Juan basin. Analytic models of permeability increase during depletion …

This paper reviews recent developments on the cleat-scale characterisation of coal. Novel
micro-CT imaging and image calibration methods are described. The application of micro …

The evolution of coal permeability is very complex under the influence of coupled multiple
processes. This is the primary motivation why numerous coal permeability models have …

Coal seam gas (CSG), also known as coalbed methane (CBM), is an important source of
gas supply to the liquefied natural gas (LNG) exporting facilities in eastern Australia and to …

Permeability increase in coalbed methane (CBM) reservoirs during primary depletion,
particularly in the San Juan Basin, is a well accepted phenomenon. It is complex since it is …

There has been a rapid evolution of technology used to evaluate unconventional gas
reservoir and hydraulic-fracture properties, and there currently are few standardized …

The reservoir engineer involved in the development of unconventional gas reservoirs
(UGRs) is required to integrate a vast amount of data from disparate sources, and to be …
