Coal-bed methaneCoal-bed methane will avert a natural gas crisis
Don't bet on it. In the United States, the practice of removing methane from ancient coal seams has proven to be a controversial and emotion-laden issue, given aquifer depletion, contamination and other problems. To date, Canada's coal-bed methane industry has drilled nearly 3,000 wells, but its political and economic future remains uncertain amid heavy public and government consultation. Despite 20 years of conflict-laden pumping, the United States has yet to coax more than 8.5% of its natural gas from coal seams. Yet the National Energy Board predicts the industry could somehow milk between 13% and 23% of Canada's supply from coal-bed methane by 2025. Right now, about 0.5% of our gas comes from coal- bed methane seams in farm country northeast of Calgary.
According to a recent paper by the National Energy Board, coal-bed methane production can grow only with mind-boggling feats of intensive drilling. Projects in central Alberta between Calgary and Edmonton could further industrialize the landscape with up to 50,000 wells, and turn rolling prairie into "a manufacturing process," says the report.
Coal-bed methane production is already proceeding at a rapid pace in the West, but few analysts expect it to make up for conventional declines. "If we are going to meet the NEB prediction," says Hughes, "we have a lot of work to do."
