AGA; U. S. gas reserve additions lag production
The American Gas Association estimates 1991 U.S. natural gas reserve additions were only 65-79% of production, compared with a 96% average for 1981-90. AGA found that 75% of 1991 reserve additions occurred as discoveries and field extensions, and only 25% came from revisions of estimates. Total reserve additions may range from 11.1 tcf to 13.4 tcf. The 30 largest gas reserves holders sold more than 1.1 tcf of reserves to other firms. The top 30 companies had reserve additions of 5.754 tcf, down 3.541 tcf from a year earlier. Total gas reserves held by the top 30 dropped by 3.757 tcf. The 30 companies produced 8.417 tcf in 1991, compared with 8.352 tcf in 1989. This paper reports that AGA compiles the reserve addition estimates from data the 30 largest gas companies file with the Securities and exchange Commission, supplemented with data from gas pipelines holding large reserves.
