No new development or exploratory wells were drilled for oil or gas in Maryland during the year. Drilling activity decreased in Ohio during the year with 1,238 new wells drilled compared with 1.355 drilled in 1970. Most of the new wells (83.8%) were completed in the Silurian Clinton Sandstone. Pennsylvania's drilling activity decreased 10%, crude oil production decreased 5%, and natural gas production decreased 1% compared with 1970. As in 1970, the majority of the deep development drilling was in the Medina (Silurian) gas area of Crawford County. Virginia's 1970 drilling program continued into 1971, with 13 wells averaging 4,000 ft in depth. The productive zone was commonly Berea with average open flows of more than 1,000 Mcf. An important deep test was completed at a total depth of 6,272 ft in the basement complex. There was a sharp decrease (12.4%) in the total number of new wells drilled in West Virginia during 1971 compared with 1970. Total exploratory drilling also regited by Prof. J.A. Czubek from Institute of Nuclear Physics in Cracow.
