ABSTRACT
A decline of 11 per cent occurred in the total number of wells completed in the shallow-sand territory of western Pennsylvania (Upper Devonian or higher) during 1947, as compared with 1946. Sixteen new gas pools were discovered, none of which, however, gives indications that it will be of very significant size. No new oil pools were discovered. In the Pennsylvania part of the Bradford oil field, which was the most active area, 1840 new wells were completed, as compared with 2153 in 1946. About half of these were water-intake wells. The Bradford field accounted for 82 per cent of the total oil production in Pennsylvania during 1947. The average daily production in the state in 1947 was 35,242 barrels, as compared with 36,383 barrels in 1946.
Twenty-eight deep wells (Onondaga or deeper) were completed in 1947. Ten of these were gas wells, 6 were drilled for gas storage, and 12 were dry holes. One of the gas wells, located in Wayne Township, Erie County, opened a new Medina sand pool.
