With this background, the committee and workshop participants examined current assessments of the world and of North American natural gas resources.

Total assessed gas resources for the United States have been increasing over the past 20 years, despite production and the transfer of potential resources to proven reserves. This is a change in our perception of the resource base, not an actual increase in the amount of gas reservoired in the Earth's crust (Scott Tinker, University of Texas at Austin, personal communication, 2003~.

A total of 1,289 Tcf of technically recoverable resources has been reported for the United States by the EIA, using predominantly USGS and Minerals Management Service data (see Figure 3.3) (Mary Hutzler, EIA, personal communication, 2003~.

able at $3.34/Mcf in 1994 dollars, compared to the total assessed resource (see Figure 3.6~. Additionally, a significant percentage of the future gas resources of the United States is off-limits due to state and federal land-use restrictions.

For example, while 27 percent of the remaining gas resource in the federal outer continental shelf is assessed for Alaska, no pipeline exists or has even been approved to transport gas to the lower 48 states (Richie Baud, Minerals Management Service, personal communication, 2003~.

On a more positive note, the first coalbed gas production in Canada began in Alberta in 2003. The Western Canada Sedimentary Basin of Alberta, British Columbia, and Saskatchewan is the premier gas-producing region of Canada and the basin that supplies almost all of the gas exported to the United States (Greg Stringham, Canadian Association of Petroleum Producers, personal communication, 2003~.

Reported reserves of nonassociated gas range from 9 to 21 Tcf, with a total gas reserve base, including associated gas, of 76 Tcf (Alfredo E Guzman, Petroleos Mexicanos, personal communication, 2003~.

Other projects are or have been conducted offshore of Oregon and in the Gulf of Mexico. As a measure of the growing importance of gas hydrates to future supply planning, the Minerals Management Service is beginning to assess hydrate occurrence (Pulak Ray, Minerals Management Service, personal communication, 2003~.

Mexico will most likely remain a net importer of natural gas. LNG imports and perhaps hydrates may be required to augment the North American gas supply.
