LAWRENCE, Kan. (AP) _ Data from the Kansas Geological Survey show oil production in Kansas last year was up over 2011, but natural gas production was down.
Officials with the survey, based at the University of Kansas, report the 43.7 million barrels of oil produced last year were the most since 1995. The oil had a value of $3.7 billion.
The survey also reported that Kansas natural gas production declined from 312 billion cubic feet in 2011 to slightly less than 300 billion cubic feet last year, a drop of 4 percent. The value of the gas declined 34 percent last year to about $790 million.
Ellis County was the state's largest oil producer with 3.6 million barrels in 2012. Stevens County produced the most natural gas, with 40 billion cubic feet.
