Study on the Influence of Deep Coalbed Methane Horizontal Well Deployment Orientation on Production

open access: yesEnergies
The development of deep coalbed methane has become an important way to obtain natural gas in China. The development of deep CBM mainly depends on horizontal well technology.

Coalbed methane producibility from the Mannville coals in Alberta, Canada: A comparison of two areas [PDF]

open access: yes, 2008
International audienceThe Mannville coals in the Fenn area, Alberta Plains, have desorbed gas content averaging 8.57 cm3/g (275 scf/t), which is similar to the same coals in the Corbett Creek area, almost 400 km away.

Design of a Pressure-Preservation Coring Tool for Deep and Ultra-Deep Coalbed Methane Samples

open access: yesShiyou jixie, 2020
Conventional coalbed methane coring tools and pressure/temperature-controlled oil-gas coring tools are difficult to obtain valuable coal cores from deep coal reservoirs.

Prediction of competitive adsorption on coal by a lattice DFTmodel [PDF]

open access: yes, 2018
Adsorption is one of the main mechanisms involved in the ECBM process, a technology where CO2(or flue gas, i.e. a CO2/N2mixture) is injected into a deep coal bed, with the aim of storing CO2by simultaneously recovering CH4.

Methyl-compound use and slow growth characterize microbial life in 2-km-deep subseafloor coal and shale beds [PDF]

open access: yes, 2017
The past decade of scientific ocean drilling has revealed seemingly ubiquitous, slow-growing microbial life within a range of deep biosphere habitats. Integrated Ocean Drilling Program Expedition 337 expanded these studies by successfully coring Miocene ...
