Title: Developments in Eastern and Northwestern Colorado in 1974

Author(s): Louis C. Bortz (2)


Exploratory and development wells drilled in eastern and northwestern Colorado in 1974 were up 17% from 1973; the success ratio increased from 42.6% in 1973 to 50.9% in 1974. Exploratory drilling was down 15.4%, but development drilling increased 65.2%. During 1974, 323 exploratory tests were drilled in Colorado and, of these, 25 found oil and 24 found gas. Development drilling was accelerated in all of Colorado but was most concentrated in the western Denver basin in the Wattenberg, Spindle, Surrey, and Third Creek fields. A decrease in both development and exploratory drilling is expected in 1975.
