Five new gas fields and 4 new oil fields can be called 'significant new discoveries' found by exploratory drilling during 1980. In the onshore area of California, 1,757 development wells were drilled during 1980; 97% were successfully completed as producers.
For the California offshore, just 7 exploratory well completions were reported for 1980; only 2 were successful. Seventy-two development wells were drilled; 65 of these (90%) were successful.
For both the California onshore and offshore, the total exploratory footage drilled in 1980 was higher, but the total number of successful exploratory wells was down 9.4% from 1979.
Notable industry activity in the California onshore area during 1980 included Shell's operations and plans for properties acquired from Belridge Oil Company, the experimental recovery project being conducted by Barber Heavy Oil Process, Inc., in Kern River field, Gulf's planned fire flood in Fruitvale field, and Getty's mining program in McKittrick field.

In Oregon, development of the Mist gas field, discovered in 1979, continued through 1980. The field, located in Columbia County in the northwestern corner of the state was producing 13.1 mmcf gas/d by June 1980. Another major test is being drilled by Texaco in Crook County.
