Gail,
The US used 22Tcf NG in 2008(62Bcf/day), so a LNG import capacity of 13Bcf/day is >20%, sounds like this capacity is vastly under utilized if only 3.5% NG was LNG imports. What about NG coming from Mexico LNG terminals? Is this counted as LNG or just pipeline imports from Mexico?

Neil -- I couldn't find country specific import data for LNG but the report below indicates that there is probably no LNG imported from Mexico. I know for some time Mexico had been a net importer of pipeline NG from the US. They have also been importing the bulk of refined products for some time also...serious lack of refining capability. I think the report indicates the situation for NG remains the same:

"In 2007, the United States received 99.8 percent of its pipeline-imported natural gas from Canada with the remainder from Mexico. Canada also accounted for 60 percent of pipeline natural gas exports, and Mexico, 40 percent."

we have this from xom's annual rept:

"by 2030 lng demand is expected to represent about 15% of the world's gas demand"

and, "exxonmobil is currently participating in lng operations in qatar and indonesia with a combined gross capacity of approximately 35 million tons per year supplying lng to markets in asia, europe and north america. this represents about 20 percent of global industry capacity. exxonmobil is participating in four additional lng trains in qatar that will increase gross capacity by over 30 million tons per year in 2009"

1 million tons of lng(methane) is about 47.4 bcf. i think i have this right:

2000lbs/ton/16lbs/lb-mole = 125 lb-moles/ton 1 lb mole is about 379.5 scf, 125 x 379.5= 47,438 scf/ton and a million tons is 47,438 x 1e6/1e9 = 47.4 bcf/million tons.

also from xom's annual report:"rasgas trains 6 and 7 - two 7.8-million-tons-per-year lng trains........with start-up planned in 2009..... train 6 is planned to supply the u.s. market,...."

7.8 million tons per yr is a little over 1 bcfd.
