From the Introduction:
Historically, thirty-six of Colorado’s 63 counties have produced oil and thirty-nine counties have produced natural gas. At the end of each county list is a bar graph and table which reports that county’s annual gas and oil production from 1980 to 1996. There is a coalbed methane (CBM) bar graph and table for seven of the counties.
