Coalbed methane content prediction using deep belief network

Interpretation, 2020
Abstract Accurate measurement of coalbed methane (CBM) content is the foundation for CBM resource exploration and development. Machine-learning techniques can help address CBM content prediction tasks. Due to the small amount of actual measurement data and the shallow model structure, however, the results from traditional machine ...

Simulation of Deep-Coalbed-Methane Permeability and Production Assuming Variable Pore-Volume Compressibility

Journal of Canadian Petroleum Technology, 2010
Summary One of the horizons of interest for future unconventional-resource development is deep- (> 5,000 ft) coalbed-methane (CBM) production. Unfortunately, coal permeability is highly sensitive to changes in stress, leading to the belief of limited permeability in deep coals.

Experimental Study on Dynamic Changes of Physical Properties in Deep Coalbed Methane Reservoirs

Geological Journal
ABSTRACT There are abundant deep coalbed methane (CBM) resources in the Ordos Basin, which have great exploration and development value. However, the special geological environment caused by deep burial of resources, such as high temperature, high reservoir pressure, and high stress, leads to significant differences in the physical ...

Quantitative Evaluation of Deep Coalbed Methane Content: A Logging Data‐Driven Approach

Geological Journal
ABSTRACT Accurate evaluation of gas content in deep coal seams is essential for estimating coal‐bed methane reserves and enabling efficient development. Conventional gas content prediction methods primarily target adsorbed gas, rendering them unsuitable for deep coal reservoirs with abundant free gas.
