In‐situ temperature‐depth profile evaluation of South African unmineable coal seams to determine CO2 sequestration potential

The Canadian Journal of Chemical Engineering, Volume 102, Issue 4, Page 1381-1394, April 2024.
Abstract This study aimed to investigate the sorption behaviour of South African coal seams with relation to the effect of temperature during CO2 sequestration. The excess adsorption isotherms of CO2 adsorption were undertaken using a high‐pressure volumetric system for four coals of different coal rank (denoted by Somkele [SK], anthracite KZN [AN ...

Factors influencing productivity and production system optimization for deep coalbed methane in the Daning-Jixian block, Ordos Basin

Meitian dizhi yu kantan
ObjectiveDeep coalbed methane (CBM) reservoirs are characterized by ultra-low porosity, ultra-low permeability, and super saturation, rendering it impractical to copy the productivity models of shallow coalbed methane and shale gas.

Application of CBM horizontal well development technology in the roof strata close to broken-soft coal seams

Natural Gas Industry B, 2019
Broken coal structure and low permeability are the main reasons for the difficult production of coalbed methane (CBM) in broken-soft coal seams. In this paper, No.8 coal seam in the Luling Mine of the Huaibei Coal Field was taken as an example to study ...
