New Waterless Fracking Process Could Work in Some WV Wells

Monday, August 17, 2015   

CHARLESTON, W.Va. – A new process that could be suitable for some West Virginia gas wells uses no water for hydraulic fracturing.

One big criticism of fracking is that drillers typically inject millions of gallons of surface water into each well.

Doug McMillan, senior vice president of operations for GASFRAC, Inc. based in Calgary, says the new process uses liquid butane or propane instead.

He points out those are hydrocarbons that occur naturally with the gas anyway – and his company uses a closed system designed not to let those products leak.

"When we go out to treat a well, it's 100 percent, could be a distillate or it's a hydrocarbon from that formation,” he says. “So no water at all."

McMillan stresses that his company’s process doesn't work well with every kind of natural gas shale. He says it's not really suited to the Marcellus, but works better with Utica shale. It's now in use at a few wells in Ohio.

McMillan says it is more difficult and expensive to make a fully sealed, closed loop system. And he says butane is a lot more expensive than surface water. But he says it's cheaper in the long run because there is no waste.

McMillan says any of the butane or propane that comes back with the gas isn't wasted.

"Whether it went through a refinery or went to a tank farm or whatever, we can use that product,” he states. “And it's completely out of the ecological water cycle."

Observers point out that eliminating the use of surface water would not make fracking pollution free. They say that some of the worst pollutants are in the naturally occurring brine that comes up with the gas.

McMillan says the kinds of rock formations where their process works don't produce much brine. Plus he says GASFRAC only uses a few, very safe additives – materials that could be found at a pharmacy.

"Pretty standard stuff, like we use a magnesium oxide, just standard mineral oil that you'd find in a face cream, and we combine that with the butane," he explains.
