... Abstract Coalbed Methane (CBM), also known as Coal Seam Gas (CSG) or Coal Seam Methane (CSM) in Australia is fast becoming a significant contributor to the country's energy needs. The potential coal seams for methane production in Australia are found in coal zones that are Jurassic to Permian...

... hydrate dissociation. Preliminary, 1-D simulations show that injection of CO 2 -microemulsion produces considerably more amount of methane than warm water injection alone. These results have also demonstrated that injection of liquid CO 2 -microemulsion helps in early and significant methane production...

.... It is shown that despite the conservative estimates of the reserves, coal bed methane production from the Zonguldak Basin is a feasible project. P. 227 coalbed methane complex reservoir information simulation reserve estimate reserves evaluation upstream oil & gas zonguldak basin coal...

... based on initial reservoir engineering analysis of data gathered from field experiments performed at Rock Creek. performed at Rock Creek. Major conclusions from the analysis performed to date are 1) post shut-in methane production is not significantly reduced by water influx during normal shut...

... phase throughout the surface area of the matrix coal and as a free phase within the fracture network. Numerical simulators have been used to analyze coalbed methane production. These simulations are both rigorous and complex and require a degree of input specification which is rarely available...

... surfaces and subsequent methane production. The reservoir pressure is caused by an existing static pressure due to groundwater. Hence, unlike a pressure due to groundwater. Hence, unlike a conventional gas reservoir, gas production is obtained from coal seams by first depressurizing the coal seam, which...

... Abstract Production data from coalbed degasification wells characteristically exhibit a negative decline curve. The dynamics of this methane production are complex and interrelated. As production begins, water and free gas are often first- recovered. Continued production lowers pressure...

... into a cooperative program to measure these changes. The objectives of this program were (1) to aid near-mine degasification activities, (2) to apply the coalbed reservoir data to large-scale coalbed methane-production activities, and (3) to utilize the coalbed reservoir data in the further development of coalbed...

... Abstract An experimental procedure for determining the effectiveness of CO2 injection into methane-containing coal samples for the purpose of enhancing methane production is described. Experimental results on production is described. Experimental results on both dry and water saturated samples...
