Haynesville Shale Gas Output Rose 24% in May From Year Earlier

Haynesville Shale formation regionNatural-gas production from shale formations rose in May on increased supplies from the Marcellus deposit even after prices fell to a 10-year low, Energy Department data show.

Total output from shale formations in the continental U.S. averaged 25.58 billion cubic feet a day in May, 24 percent higher than a year earlier and up 1.7 percent from April, according to slides that accompany a presentation the department will make to Congress Aug. 1. Shale production has gained 5.7 percent this year.

Production from shale deposits with oil and other liquids has gained as dry-gas output has declined in response to decade- low prices, the department said in its Short-Term Energy Outlook on July 10. Gas futures on the New York Mercantile Exchange dropped to $1.902 per million British thermal units April 19.

May output from the Marcellus shale in the eastern U.S. averaged 6.85 bcf a day, up 6.4 percent from the previous month and gained 28 percent during the first five months of the year. May 2011 production averaged 3.37 bcf daily.

Haynesville shale output in Louisiana and Texas averaged 6.92 bcf a day, down from 6.93 billion in April. Production from the region has declined 2.4 percent this year. Output averaged 6.43 billion cubic feet a day in May 2011.
