Notes: OGJ's annual look at worldwide gas reserves shows an increase to 6,746.8 trillion cubic feet/tcf from 6,647.3 tcf in last year's survey. Total gas reserves for OPEC are up nearly 4% from a year ago. Reported gas reserves climbed by 12% in Iran to 1,168 tcf and declined in Libya by 3% to 52.8 tcf. As of Jan. 1, 2012, OPEC's gas reserves totaled 3,330.1 tcf, or 49% of the worldwide total. Dry natural gas proved reserves in the United States were estimated at 272.5 tcf for 2009, according to the U.S. Energy Information Administration. EIA also reported that proved reserves of wet gas, which includes natural gas plant liquids, increased by 11% in 2009 to 284 tcf. This is their highest level since 1971. Shale gas development in Louisiana, Arkansas, Texas, Oklahoma, and Pennsylvania drove the increase in proved reserves of natural gas. Louisiana led the nation in wet natural gas proved reserves additions with a 77% increase of 9.2 tcf owing primarily to development of the Haynesville shale. Please read Marilyn Radler, "Worldwide Oil Production Steady in 2011; Reported Reserves Grow," OGJ, Dec. 5, 2011. According to the OGJ, Australia is not in the Top 15 this year? -- D.R.

* OPEC member. Data for Kuwait and Saudi Arabia exclude one-half of the reserves in the Kuwait-Saudi Arabia Neutral Zone. Neutral Zone contains 1,000 bcf, i.e. 1 tcf, of gas reserves.

**Including also Angola, Ecuador, Libya, Kuwait and the Neutral Zone.
