ABSTRACT
This is the seventh annual report on data gathered by the committee on statistics of exploratory drilling.
During 1951, 11,756 exploratory holes were drilled in the United States. Of these 6,189 were new-field wildcats, 3,062 were new-pool tests (including new-pool wildcats, deeper-pool tests, and shallower-pool tests), and 2,503 were outposts. Among the new-field wildcats, 684 were successful; among the new-pool tests, 851 were successful; and among the outposts, 680 were successful.
The total exploratory footage drilled in the United States in 1951 was 49,343,694 feet in the 11,756 holes, or 4,197 feet per hole. These figures compare with 40,175,173 feet drilled in 10,306 exploratory holes, with an average depth of 3,898 feet in 1950. For the fourth time we are presenting data on Canada and Mexico.
