State's oil production up in 2012May 29, 2013 The Associated Press
Wyoming oil production topped 57 million barrels last year.
The Wyoming Oil and Gas Conservation Commission reports that the production total represents an 8 percent bump since 2003 and an 11 percent increase since 2009.
Bruce Hinchey, of the Petroleum Association of Wyoming, attributes much of the increased production to new technology that results in more oil being extracted.
But while the state oil production has been increasing in recent years, it is still nowhere near the state's all-time peak. In 1978, statewide production topped 135 million barrels.
