Deep Injection Well Construction Booms Despite Push to Recycle
Drillers use deep injection wells as one option to dispose of drilling waste deep underground. EnergyWire reports on the number of waste disposal wells under construction, or pending permits, in Ohio and Pennsylvania.
“In Ohio, 16 new wells are under construction to take waste “brine” from oil and gas wells. Seven have been granted permits but have not yet been drilled, according to figures provided by the Ohio Department of Natural Resources. An additional 20 applications for new brine wells are under review.”
“Though less than 8 percent of the brine, used fracturing fluid and drilling waste from Pennsylvania Marcellus wells is injected into disposal wells, that’s up from a little more than 6 percent in 2010. And state records show that the total amount of waste being sent to injection wells has gone up nearly 500 percent since 2010.”
