ALBERTA RESERVES SHOW 1991 DECLINE
Alberta's conventional crude oil reserves declined 8% or 264 million bbl to 2.9 billion bbl in 1991 from 1990, the provincial Energy Resources Conservation Board reports. ERCB data show the province had a 9 year supply of conventional crude remaining at current production levels as of Dec. 31, 1991. The board also estimated Alberta has 3.6 billion bbl of undiscovered reserves. The level of recovery will depend on economics and advances in technology.
