ABSTRACT
Washington: Eight new-field wildcats abandoned; 37,792 feet drilled.
Oregon: Five new-field wildcats abandoned; 27,278 feet drilled.
California: Six hundred fifty-one exploratory wells with a total footage of 3,345,042 were drilled in California during 1955. This is an increase of 3 per cent in the number of wells and 13.8 per cent in total exploratory footage over 1954. Exploration was 15 per cent and 17.3 per cent successful as to wells and footage, respectively. Comparable figures for 1954 are 14.4 per cent and 17.4 per cent. Discovery record: 15 fields, 11 oil and 4 gas; 47 pools, 37 oil and 10 gas. Approximate production in 1955; crude oil 354.8 million barrels, down 0.3 per cent from 1954; natural gas liquids, 30.8 million barrels; natural gas, 513.5 billion cubic feet (includes gas from dry gas fields and residue gas from oil fields). Basement was reached in 47 unsuccessful exploratory holes. There were 71 active exploratory holes at the end of the year.
