This includes well drilling and fracking, ongoing oil and gas production, installation and operation of pipelines and compressor stations, cryogenic separation plants and admin offices. There are a combined 6,056 active oil and gas wells in the county. Washington County has the most Marcellus fracked shale gas wells in all of Pennsylvania, 1,146 wells. Each well used about 4.5 million gallons of water during the fracking process.
