Comparison of gas content evaluation methods in the log interpretation of coalbed methane
RESOURCES AND SUSTAINABLE DEVELOPMENT, PTS 1-4(2013)
Abstract
In the log interpretation, the CBM content evaluation methods include: regression, LAN's equation, KIM method, neural network, and so on. This paper investigates the suitability of these methods for a CBM reservoir in Southern Qinshui Basin, Shanxi Province of China, and finds out the most reasonable interpretation model of CBM content in this area. The results show that the composite parameter(COMP) method and the LAN's equation method are more suitable for evaluating the CBM content in this study area, while the other methods are not.
