Methane Recovery From Deep Coalbeds in the Book Cliffs
Proceedings of SPE Unconventional Gas Recovery Symposium, 1982ABSTRACT A project jointly funded by Mountain Fuel Supply Company and the U.S. Department of Energy is being conducted to show the commercial potential of recovering methane gas from deep coal seams in the Book Cliffs coal field in Central Utah.

A Method for Evaluating the Methane Content of the Nanoscale Pores in Deep Coalbeds
Journal of Nanoscience and Nanotechnology, 2021Since the sampling depth is large in deep coalbed methane wells, during the lifting process of coalbed cores, the core surface pressure drops nonlinearly with time, which is contradictory to the premise of the conventional United States Bureau of Mines (USBM) method and the Smith-Williams method.

Journal of Natural Gas Science and Engineering, 2018
Abstract Deep coalbed methane (CBM) resource potential is enormous in China, and has become a new field for unconventional natural gas exploration and development. This work discusses the geological conditions (reservoir pressure, formation temperature and ground stress) of deep coal reservoirs in the Eastern margin of the Ordos Basin and their ...

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.

Coalbed methane content prediction based on deep belief network
Coalbed methane (CBM) is considered an unconventional gas resource. Accurate determination of CBM content can provide potential disaster warnings and guide exploration and development. Direct measurement and statistical analysis of CBM content are common techniques.Wenfeng Du, Suping Peng, Xiaoqin Cui

Study on Evaluation System for Coalbed Methane from Deep Coal Seams in China
Advanced Materials Research, 2014In 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.

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