HOUSTON, May 17 -- The Canadian Gas Potential Committee estimated total original gas in place in Canada at 652 tcf, 10% more than the committee's 2001 estimate.
The committee increased its nominal marketable gas estimate 6% to 367 tcf.
Most of the increase is from established plays in the Western Canada Sedimentary Basin. Estimates for frontier basins are 188 tcf of OGIP and 88 tcf of nominal marketable gas. The frontier 188 tcf is composed of 63 tcf of discovered gas and 125 tcf of undiscovered gas.
The volunteer group put original coalbed methane in place at 528 tcf, and it set a first-time estimate of nominal marketable CBM for all areas at a most likely 26 tcf. The range is 11 to 45 tcf.
"Unconventional gas sources will provide important gas supplies in time," the committee predicted. It declined to provide marketable gas estimates for shale gas or gas hydrates.
In 2001, the committee estimated that CBM constituted an in situ resource base of 190 to 568 tcf, but no commercial production existed at the time and so none of the resource was estimated to be marketable.
The latest report is based on yearend 2002-03 data, roughly 4 years newer than the data in the 2001 report.
The committee makes the report available through the Canadian Centre for Energy web site at www.centreforenergy.com.
