Therefore, China is looking forward to develop its unconventional potential which is expected to be comparable to that of North America. The resources are located in the Tarim Basin (North...

... the geothermal temperature gradient and advances in quantitative production profiling. A multi-well study was conducted in the Piceance Basin in Northwestern Colorado because of the unique effect of lithology on the geothermal gradient. Coal, sand and shale sequences which impact the geothermal gradient must...

.... Characterization of gas movement and sorption capacity of coal at in-situ conditions is required. Using the volumetric method, measurements of CH 4 and CO 2 sorption and diffusion in coal have been made on powder and non-powder confined coal. Evaluation of sorption capacity and transport rates of gases in coal...

... Abstract This paper discusses the successful application of the operator's drilling performance management process in the Australia Snapper / Moonfish platform drilling program. Snapper performance has historically been limited by shale instability, collapsing coal seams, lost returns...

... fuels is expected to be offset by small projected (percentage) increases in the use of coal, gas and renewable sources [ EIA, 2007 ; NPC, 2007 ]. The growth in energy use is related to both population increase and economic growth measured in per capita gross domestic product (GDP). In order to meet...

... historical price effects. Inflation jumped four-fold with the high prices in the 70's and 80's. During the 74-year period of history match, US energy demand grew fourfold, population more than doubled, and real GDP grew 12-fold. Oil and gas use rose from 18% of total commercial energy to 63%, and coal...

... more wells will be drilled in the next 5-10 years. Wells in this basin are now trending towards a much higher percentage being cased and perforated multizone completions rather than open hole completions in a single interval. Abstract Worldwide Coal Bed Methane (CBM) resources are huge, estimated...

... Abstract The Horseshoe Canyon coal formation in Alberta, Canada is an anomaly for coals. It is dry, for the most part producing no formation water. Therefore, no dewatering is required. In fact, it is severely damaged by water influx. Normal permeability injection tests and conventional...

... to exceed 3,000 wells per year in 2005. 1 The Horseshoe Canyon CBM play covers a large geographic area of 200 miles by 50 miles, and exists in a large, complex vertical section with numerous coal, sand, silt, shale and mudstone layers. In addition, the play is naturally under-pressured, and the coal...

... Abstract We provide a summary of coal failure during the life of a typical coalbed methane (CBM) well, and some consequences for the CBM industry. Because coals are weak in general, these consequences are often important, and can have a significant impact on drilling, completion, and production...

... Abstract Sorption-induced strain and permeability were measured as a function of pore pressure using subbituminous coal from the Powder River basin of Wyoming, U.S.A. and high-volatile bituminous coal from the Uinta-Piceance basin of Utah, U.S.A. We found that for these coal samples, cleat...

... significant, if generally short-term, oil price hike. Economic growth has happened when oil prices were either relatively low or stable. The oil price jump of the '70s also correlates with a nine-fold increase in natural gas price, a four-fold increase in coal price, a three-fold increase in cost...

... Abstract Just over ten years ago, coal bed methane production from Wyoming's Powder River Basin was virtually non-existent. Today, total gas production from Powder River Basin coals is almost 1 Bcf per day from nearly 10,000 wells. This tremendous resource is unique compared to other commercial...

Propped hydraulic fracture completions have been successful in stimulating production from conventional reservoirs from microdarcy to darcy rocks...

... testing may prove to futile for the purpose of potential gas production of the reservoir(s). Rather, the goal of these wells should be to evaluate the permeability of the individual coal seams. Because of the extensive testing performed on these initial data wells, the costs of these wells is typically 1...
