Former owner's name on top of envelope. ; Map #3, 1977 edition; This map shows oil, natural gas, and gas storage fields and pools of Pennsylvania. It is based on 15-minute topographic bases. The most significant production of oil presently is from the Bradford field, which produced approximately 44% of Pennsylvania's crude oil production in 1976. Most of the oil comes from McKean, Venango, Warren, Forest, and Washington Counties. The county that currently produces the most natural gas is Indiana, but substantial amounts of gas are being produced in Armstrong, Clearfield, and Westmoreland Counties. The current largest gas storage field is Oakford in Westmoreland County; Leidy in Clinton County is next largest in size. Principal natural gas and crude oil and product pipelines are included.
