Coalbed Methane. 2015 - 2019 Bibliometric Analysis [PDF]

, 2019
Motivations: It is estimated that the forecasted methane resources of Russia's main coal basins contain 83.7 trillion cubic meters, representing roughly one-third of the country's natural gas reserves, but the production of CBM is rather small.

A High Efficiency Low Damage Fracturing Fluid for Deep Coalbed Methane Development

Zuanjingye yu wanjingye
In developing deep coalbed methane (CBM), existing fracturing fluids have deficiencies such as poor sand carrying capacity and high core damage. To overcome these deficiencies, a fracturing fluid system (HMP/OP) was developed with a main fracturing fluid

World coalbed methane projects [PDF]

, 2002
Worldwide coalbed methane resources, once considered as a new "unconventional" natural gas resources, are now being recognised as a potential source of methane in many countries with extensive coal basins. Coal deposits occur abundantly in many locations
