Drilling activity in eastern and northwestern Colorado was up approximately 10% from 1430 wells in 1983 to 1589 wells in 1984. This increase in total wells drilled resulted mainly from development activity. The success rate for the 488 exploratory wells drilled in 1984 was 24%, down about 7% from the 1983 level of 31%. Activity in eastern Colorado focused on Pennsylvanian and Mississippian rocks along the Las Animas arch and northern Hugoton embayment. Drilling for Cretaceous formations in the Denver basin increased with much of the new activity centered around the Codell sandstone and Niobrara Formation near Greeley. Significant new Niobrara production was established in northern Weld County. In the San Luis Valley of south-central Colorado, oil shows were reported for the first time in the Cretaceous Dakota Formation beneath volcanic rocks. 1 figure, 2 tables.
