Tuscaloosa Sand, "geopressured" zones could raise nation's supply...
...well's importance goes far beyond that. Its discovery indicates that a major new gas-exploration effort in the Tuscaloosa Sand geological formation of southern Louisiana is hitting pay zones. That promises new production not only for Louisiana but for an energy-hungry nation that counts natural gas as both its cleanest-burning and most critically scarce fuel. Last week the Louisiana Office of Conservation estimated that gas reserves in the Tuscaloosa Sand may reach 3 trillion cu. ft. That would be equal to 86% of last year's production in Louisiana, which leads the nation...
...Parlange well extended the known limits of the Tuscaloosa Sand, which is named for the Alabama county where it crops to the surface. In Louisiana, the "trend" (main potential gas-producing formation) lies four miles beneath the green bayous and sugar-cane fields and stretches 200 miles from Lake Pontchartrain to the Texas border. Because of its depth, high temperature and geological history, the Tuscaloosa Sand has produced mostly gas, very little...
Exploration crews have been probing the Tuscaloosa Sand since the early 1960s, but the gas proved elusive. Formed 65 million years ago in northern Louisiana and swept southward by ancient rivers, it lay hidden under a layer of limestone that distorted the echoes of shock waves by which geologists map underground formations. But a Chevron geologist's hunch, confirmed by tests using computer techniques, led prospectors to a swampy field on the Parlange plantation. When the drill bit spun into a zone of extreme pressure 21,345 ft. down, the gas and steam crushed the well casing, ripped...
...acre and a one-third share in future production. The state of Louisiana, controlling 5 million acres, leased land on the bottom of Lake Pontchartrain for $324 an acre and a choice site elsewhere at $1,500 an acre in competitive bidding. So far, the Tuscaloosa Sand has yielded 14 producing or potentially producing wells...
