Study on logging evaluation of key parameters of “five properties” of deep coalbed methane reservoirs

The Physics of Fluids
Deep coalbed methane (CBM) resources are vast. Addressing the complex geological characteristics of deep CBM reservoirs, which include the coexistence of adsorbed and free gas, complex occurrence mechanisms, significant heterogeneity, and elevated ground

Study on Evaluation System for Coalbed Methane from Deep Coal Seams in China

Advanced Materials Research, 2014
In this study, data from 244 CBM production wells were collected and analyzed in China. Based on the data, coalbed methane (CBM) reservoir properties and geological factors were studied. Combined with previous study results, the current situation of CBM resource evaluation, the classification of evaluation indexes and evaluation standard were analyzed.
