ABSTRACT
A new coal-bed
methane production technology has the added attraction
of tackling greenhouse gas emissions. Injection of carbon
dioxide, an important anthropogenic greenhouse gas, into
deep coal seams can enhance methane recovery, while simultaneously
locking up the carbon dioxide in the coal measure. Providing
the coal is never mined, the carbon dioxide would be sequestered
for many years, and thereby help to avoid climate
change. Initial results from the world’s first carbon dioxide-
enhanced coal-
bed
methane (CO2-ECBM) pilot in the United
States have shown this new technology to be technically and
economically feasible. Since 1996, over 57 million m3 (2 Bcf) of
CO2 has been sequestered in the coal seams. Based on current
costs and performance, CO2-ECBM may be profitable in the
United States at prevailing well-head natural gas prices of
US$0.06 to $0.07/m3 ($1.75 to $2.00/Mcf), representing an estimated
8.5 Gt of CO2 sequestration potential. The technology for
implementing and operating CO2-ECBM recovery is based on
demonstrated oil field technology, although further refinements
are needed. The worldwide CO2-ECBM potential has been estimated
at 150 Gt CO2. Analysis of representative CO2-ECBM
projects indicates that 5 to 15 Gt of carbon dioxide could conceivably
be sequestered at a net profit, while about 60 Gt of sequestration
capacity may be available at moderate costs of under
$50/t CO2.
