Economic Importance
Haynesville shale is an important shale-gas resource play in East Texas and Louisiana. Estimated recoverable reserves are as much as 60 Tcf, with each well producing on the average of 6.5 Bcf. The Haynesville Shale came into prominence in 2008 as a potentially major shale gas resource. Producing natural gas from the Haynesville Shale involves drilling wells from 10,000 feet (3,000 m) and to 13,000 feet (4,000 m) deep. The formation is deeper in areas nearer the Gulf of Mexico. The Haynesville Shale has recently been estimated to be the largest natural gas field in the contiguous 48 states with an estimated 250 trillion cubic feet (7.1×1012 m3) of recoverable gas. Production has boomed since late March 2008, creating a number of new millionaires in the Shreveport, Louisiana region.
The other members of the Haynesville Formation are also the source of oil and gas production. Oil and gas is currently produced from shelf-edge carbonate reservoirs which consist of oolite shoals within the Gilmer Limestone and Buckner Anhydrite members. The submarine fan sandstones of the Gray sand in north Louisiana are also significant producers.

Famous quotes containing the words economic and/or importance:
“We have heard all of our lives how, after the Civil War was over, the South went back to straighten itself out and make a living again. It was for many years a voiceless part of the government. The balance of power moved away from it—to the north and the east. The problems of the north and the east became the big problem of the country and nobody paid much attention to the economic unbalance the South had left as its only choice.”
—Lyndon Baines Johnson (1908–1973)
“We ought to esteem it of the greatest importance that the fictions which children first hear should be adapted in the most perfect manner to the promotion of virtue.”
—Plato (c. 427–347 B.C.)
