NG is obviously finite and will be more expensive, but that is not the same as "tapped and done." Probably oil will increase in cost much faster. Your blog link several times states it is speaking about "conventional NG" - That means what come up from the bottom of the drill pipe. Now many old fields of conventional gas are "tapped and done" with >90% of the original ng still in the ground near the down pipe end. The flow thru the porous rocks to the down pipe end is just too slow to collect with a profit. This is why they are reentering the old well and at bottom putting out many half mile long horizontal collector tubes with holes in their sides - perhaps we will get several times what has already be removed from these "exhausted" old wells. Yes, it will cost more, but NG is gaining market share on oil, for home heating as oil is esculating more rapidly in price. Investment "rag" ZACK, one of the better IMHO has daily feature called "bull of the day." (and dozen or so detailed studies of other companies.) Here is what I copied recently and condensed about one: "12June Zack’s bull: In 2006, for $33.8e6, acquired Burlington Resources, exploration and production (E&P) company, with a significant North American unconventional natural gas-focused reserve base. At end 2004, Burlington’s proved reserves totaled 12 trillion cubic feet equivalent ~ 2 billion oil-equivalent barrels, of which 69% was natural gas and 89% was located in North America. Exploration and Production: ConocoPhillips* has very large and established E&P operations in all major hydrocarbon producing regions of the world. As of the end of 2007, proved reserves of 10.6 billion oil-equivalent barrels, including its share of LUKOIL s reserves and the additions from the company s joint venture with EnCana. The company s reported proved reserves tally does not include approximately 200 million barrels associated with its Canadian Syncrude operations. Total production in 2007 averaged approximately 1.94 million oil-equivalent barrels per day, up approximately 26% from the previous year's level. Your link is just some guy's blog. - Zacks is well respected firm with many staffers and probably research budget > $100,000 annually. ----------------- *I do not own any ConocoPhillips, but have been tempted a few times to buy some.
