Underground Storage of Natural Gas by Interstate Pipeline Companies for 1980 and Winter 1980-1981

摘要

Estimated underground storage capacity in the USA amounted to 4.4 trillion cubic feet, a 2.2% increase over 1979. The utilization of storage gas during the highest consecutive 3-day system peak in the 1980-1981 winter season was 27.6% of the total system deliveries during that period, as compared to 30.2% in the 1979-1980 winter season. Data from 217 underground storage fields reported by 31 jurisdictional interstate natural gas companies were used in the compilation. Honoeye Storage Corporation and Hampshire Gas Company are exempted by the Federal Energy Regulatory Commission (FERC) from filing information on financial data. Because the financial data from these companies are not available, the financial data of only 29 companies with a total of 215 underground storage fields appear in this report. During 1980, three new storage fields were put in operation by jurisdictional pipeline companies. Eleven certificates were issued by the FERC for changes in eleven existing storage fields, including seven amendments for previously issued certificates. The 215 underground gas storage fields operated by the 29 jurisdictional companies as of December 31, 1980 consisted of 175 expansion reservoirs, 17 water drive reservoirs, and 23 aquifer reservoirs, as shown in Table 3. Expansion reservoirs are pressure depletion type reservoirs. Water drive reservoirs are depleted gas or oil reservoirs in which the producing mechanism consists primarily of movement of water into the reservoir as the reservoir fluid is produced. Aquifers are reservoirs that originally contained only water. (ERA citation 07:045770)
