Analysis of Coalbed Methane Inter-Well Interference

Advanced Materials Research, 2013
On the base of the storage, migration and production mechanisms of Coalbed Methane (CBM), the gas-water two phase differential equations describing the seepage of CBM are set up to calculate reservoir pressure and productivity in vertical well pattern, to analysis the propagation characteristics of formation pressure and the influence of inter-well ...

BENEFITS AND PROBLEMS OF MINIFRAC APPLICATIONS IN COALBED METHANE WELLS

Proceedings of CIM/SPE International Technical Meeting, 1990
Abstract In conventional oil and gas reservoirs, the use of prefrac pump-in tests, in conjunction with analysis of the shut-in pressure response, has been a tremendous asset in Improving fracture stimulation designs. Since its introduction in 1979, many modifications and improved analysis techniques have evolved to increase the value of "

Production Data Analysis of Coalbed-Methane Wells

SPE Reservoir Evaluation & Engineering, 2008
SummaryRecent advances in production data analysis (PDA) techniques have greatly assisted engineers in extracting meaningful reservoir and stimulation information from well-production and flowing-pressure data. Application of these techniques to coalbed-methane (CBM) reservoirs requires the unique coal storage and transport properties to be accounted ...

Coalbed Methane Well Production Forecasting

SPE Rocky Mountain Regional Meeting, 1992
ABSTRACT A method (NWFuel Method) has been developed to predict the cumulative production from coalbed methane (CBM) wells. This Method has been developed from actual production data from over 1,500 wells in the Black Warrior and San Juan Basins.

Coal Failure and Consequences for Coalbed Methane Wells

Proceedings of SPE Annual Technical Conference and Exhibition, 2005
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 of CBM wells.

Transient Well Testing of Coalbed Methane Reservoirs with Horizontal Wells

Permian Basin Oil and Gas Recovery Conference, 1994
ABSTRACT Natural gas production from coalbeds using horizontal wells may be of interest to producers in the future. Since sedimentary gas reserves are limited, the unconventional gas reservoirs could be an alternative resource to meet the demand for natural gas.

Review of Coalbed Methane Well Stimulation

Proceedings of International Meeting on Petroleum Engineering, 1992
Abstract Coalbed methane is an abundant resource in the U.S.A., for example, in the San Juan Basin (50 TCF), and Black Warrior Basin (20 TCF). Amoco has drilled many wells in both basins in the last few years. Different completions and stimulations have been tried, and these are summarized as follows: Openhole cavity ...

Dewatering of Coalbed Methane Wells with Hydraulic Gas Pump

Proceedings of SPE Eastern Regional Meeting, 1995
Abstract The coalbed methane industry has become an important source of natural gas production. Proper dewatering of coalbed methane (CBM) wells is the key to efficient gas production from these reservoirs. This paper presents the Hydraulic Gas Pump as a new alternative dewatering system for CBM wells.
