Igneous intrusions and thermal evolution in the Raton Basin, CO-NM: contact metamorphism and coal-bed methane generation
Tertiary mafic dikes and sills intrude coal-bearing formations of the Raton Basin. This study investigates the role of intrusions in generating methane from coal. Coal samples at four different outcrops were analyzed by vitrinite reflectance, carbon isotopes and petrography. Reflectance values at …

Identifying and Modifying the Coal Bed Methane Fiscal Regime in Indonesia: A Comparative Study with the Australia and the U.S.
… of Production Sharing Contract (PSC) applied to Coal Bed Methane (CBM) in Indonesia and modifying these using comparative examples of the U.S. Royalty/Tax (R/T) System and the Australian Petroleum Resource Rent Tax (PRRT). This research examines the issues of CBM development in Indonesia from the …

Sequence Stratigraphy and Architecture of Lower Pennsylvanian Strata, Southern West Virginia: Potential for Carbon Sequestration and Enhanced Coal-Bed Methane Recovery in the Pocahontas Basin
Carbon dioxide sequestration in coal-bed methane fields has potential to add significant recoverable reserves and extend the production life of coal-bed methane fields while at the same time providing a geologic sink for atmospheric greenhouse gases. The ability to relate the thickness, extent, and …

Parametric and predictive analysis of horizontal well configurations for coalbed methane reservoirs in Appalachian Basin
… Basin represents a high potential region for the Coalbed Methane (CBM) production. The thin coal beds in the Appalachian basin are characterized by low porosity and permeability values. Due to highly complex reservoir characteristics, different drilling techniques have been developed in order to …

Linkage Between Lower Pennsylvanian Sandstone Diagenesis and Carbon Sequestration Reservoir Quality in Russell County, Virginia
An enhanced coal-bed methane facility in Russell County, Virginia is targeting lower Pennsylvanian coals for CO2 storage, but the shallow sandstone units intercalated with the coals may also prove to be potential CO2 reservoirs, since the injection apparatus is already in place. Using samples from …

PRODUCTION FORECASTING FOR SHALE OIL: WORKFLOW
… to estimate reserves for shale gas and coal bed methane have, thus far, proved to be reliable, but no simple yet accurate workflow has been generally accepted to forecast production and estimate reserves for shale oil. To fill this gap in technology, we proposed and validated a workflow …

Insights Into the Stratigraphic Evolution of the Early Pennsylvanian Pocahontas Basin, Virginia
Early Pennsylvanian, coal-bearing, siliciclastic strata of the Breathitt Group within the Pocahontas Basin, southwestern Virginia, define a southeasterly thickening clastic wedge deposited in continental to marginal marine environments influenced by recurring, high-magnitude relative sea-level …
