Coalbed Methane

Raven Ridge began working in the coalbed methane industry in the mid-1980s. Raven Ridge has provided wellsite services, performed analytical services, resource evaluations, mapping, operations management, and/or conducted investigations on hundreds of wells throughout the U.S. Through our work on a wide variety of coalbed methane and conventional oil & gas projects we have earned a reputation as a leading consulting firm.

Raven Ridge has expertise in most U.S. coal basins, including the Cook Inlet Basin of Alaska, where we performed a technical review and economic evaluation of a potential coalbed methane production project . Raven Ridge is experienced in all phases of geological and geophysical data evaluation. We also perform economic analyses including reserve estimates, reserve valuation, and market considerations.

Coal Mine Methane

Raven Ridge has conducted numerous evaluations concerning the potential for recovery of methane from active coal mines. These analyses range from preliminary evaluations using publicly available data to in-depth evaluations incorporating extensive resource and economic data supplied by the mine. We have performed these studies for private-sector mining company clients as well as the U.S. EPA. We have also examined in detail the recovery of methane from abandoned coal mines in the U.S., and have developed a methodology for estimating emissions of methane from abandoned mines. In addition, we have helped firms verify, report, and market carbon credits, an increasingly important service as companies move forward with greenhouse emissions trading initiatives.

Underground Coal Gasification

Raven Ridge undertook two major projects concerning development of underground coal gasification (UCG) resources in the western U.S. In the more recent of these projects, we developed a program for exploration and development of UCG resources near Rawlins, Wyoming for Williams Energy Ventures. Raven Ridge developed and managed state-of-the-art drilling and completion operations, and designed a database that allowed retrieval of geotechnical information for mapping and modeling applications. We also assisted with remediation at the site.

Our in-house staff and associates have the experience and capability to undertake a wide range of energy exploration and development projects throughout the United States and internationally. Please contact us for more information.

Gas Enrichment

Gas drained from gob areas (collapsed rock over mined-out areas) typically contains 30-90 percent methane, which may not meet minimum quality specifications for injection into natural gas pipelines. Raven Ridge Resources is part owner of Gas Separation Technology (GST), a company that is developing processes for enriching low quality gas by removing unwanted contaminants. The methane drained from coal mines, for example, is frequently mixed with air and sometimes carbon dioxide. GST’s technology enables the economical recovery and use of this methane.
