The number of exploratory and development wells drilled in eastern and northwestern Colorado in 1975 increased 38% from 1974, and the success ratio increased from 50.9% in 1974 to 52.6% in 1975. Exploratory drilling was up 21.7% and development drilling was up 49.4%. During 1975, 1,131 wells were drilled of which 302 were successful oil completions and 293 were successful gas completions. Development drilling increased over the entire area and exploratory drilling increased in eastern Colorado but decreased in the northwestern part of the state. Development drilling was concentrated most in Adams and Weld Counties, primarily in Wattenberg, Spindle, and Surrey fields. An increase in development drilling is expected as infield drilling continues in eastern Colorado.
