Coalbed methane (CBM) is a potential green energy supply for addressing the worldwide energy crisis. However, the recovery of economically viable amounts of methane requires the application of production-enhancement techniques. The greater effectiveness of enhanced coalbed methane (ECBM) recovery compared to traditional pressure depletion and hydraulic stimulation Cited by: The methane from two coal seams are usually produced in the same production well, and the commingled production process is of low efficiency. In order to enhance the methane recovery from the two coalbeds, a ‘multi-branch U-shaped’ well is introduced to double-coal seams. This well structure can perform a single layer or commingled : Chao-Wen Wang, Chun-Sheng Jia, Xiao-Long Peng, Su-Yang Zhu, Feng Liu. Methane that resides within coal seams. The equivalent term in Australia is "coal seam gas" and in the United Kingdom is "firedamp".In the U.S., CBM production is defined as methane extracted from coal seams that have not been disturbed by mining. Outside the U.S., methane production from undisturbed coal seams is sometimes. Coal Bed Methane: Theories and Applications, Second Edition, captures the full lifecycle of a coal bed methane well and offers petroleum geologists and engineers a single source for a broad range of coal bed methane (CBM) applications. The vast coal resources in the United States continue to produce tremendous amounts of natural gas, contributing to a diverse range of energy assets.
The paper was presented at the SPE/DOE Unconventional Gas Recovery Symposium of the Society of Petroleum Engineers held in Pittsburgh, PA. May , The material is subject to correction PA. May , The material is subject to correct. This research, as a part of the Methane Recovery From Coal Beds Project, was sponsored by the DOE through TRW, Inc. The objective of this research was to evaluate methane potential of the unmined and unmineable coal seams in the nation. There are a variety of factors which could make a coal seam unmineable in the foreseeable future. The Hartshome, the McAlester (Stigler), and the Secor coalbeds are the most extensive and uniformly thick coals in the Arkoma Basin; estimated coal reserves are over billion tons, constituting 93% of the basin’s total coal resource. Methane Recovery from Coalbed Project (MRCP) data on the methane gas content of Arkoma Basin coals is. The well is located within an area of large biogenic gas plays (a set of known or postulated oil and/or gas accumulations sharing similar geologic properties) with coal of similar rank and age. Methane recovery from production wells in the Gulf Coast Basin (which covers parts of seven states in the southeastern United States) is similar to that.
Tight gas basins, Devonian shale, methane from coal seams, and methane from geopressured aquifers are considered. It is concluded that unconventional sources, already providing about 1 Tcf per year, could provide from 3 to 4 Tcf in and from 6 to 8 Tcf in (at $ and $ per Mcf, respectively).

However coal seam gas comes from underground at different proportions, it is mainly a mixture of methane (95%) and carbon dioxide (3%). In addition, a. The book begins with a brief review of methane emissions from Indian coal mines and the current coalbed methane situation in the country. enhanced coalbed methane (ECBM) recovery via CO 2.
