Based on the structural interpretation of seismic data, we analyzed the gas controlling effects of folds and faults on CBM accumulation qualitatively. Meanwhile, we discussed the lateral sealing ability of the major overthrust faults quantificationally by bringing in “Shale Gouge Ratio (SGR)”, which is proved to be applicable in analyzing the gas ...

Patented Foamed Chemical Technology Frees Stuck Tubing in Coalbed Methane (CBM) Wells
SPE Eastern Regional Meeting, 2009Abstract Gas and water production from CBM wells in Southwest Virginia has led to problematic deposition of mineral scales. Calcium carbonate essentially cements the production casing and tubing together, making well repairs time-consuming, difficult, and costly.

Well Testing in Coalbed Methane (CBM) Wells: An Environmental Remediation Case History
SPE Annual Technical Conference and Exhibition, 1995Abstract In 1993, methane seepage was observed near coalbed methane wells in southwestern Colorado. Well tests were conducted to identify the source of the seeps. The well tests were complicated by two-phase flow, groundwater flow, and gas readsorption. Using the test results, production from the area was simulated.

A Preliminary Study of Development of Coalbed Methane (CBM) in South Sumatra
Proceedings of SPE Asia Pacific Oil and Gas Conference and Exhibition, 2003Abstract Increasing gas demand significantly in Indonesia and its surrounding regions in the last decade affects on exploration of gas resources. Moreover, when the Indonesia government gradually cut subsidizing of oil based fuel price, then the gas price becomes more competitive. However, the conventional gas reserves are

Coalbed methane (CBM) recovery is a crucial approach to realize the exploitation of a clean energy and the reduction of the greenhouse gas emission. In the past 10 years, remarkable achievements on CBM recovery have been obtained in China. However, some key difficulties still exist such as long borehole drilling in complicated geological condition, and

Abstract In this research, a coal-gangue-rock geological model based on geological parameters was established by studying the relationships between different dielectric constants, conductivity and attenuation coefficients, and emission frequencies when electromagnetic waves were propagated in a medium.

China is rich in CBM resources, but so far, some production wells present low production and rapid decline trend. In addition to these objective factors such as low permeability and complexity of geological structure of CBM reservoir, there is still the most important problem during the exploitation techniques that is the lack of understanding to ...

Powder River Basin, Wyoming: An Expanding Coalbed Methane (CBM) Play
AAPG Bulletin, 1999Coalbed methane exploration in the Powder River basin represents an active play with considerable potential for future expansion and success. Such potential is related to the specific geology and character of the target coals, which exist in the Paleocene Fort Union Formation at depths of 300-2000 ft (91-610 m).
