Ensign’s natural-gas rigs gaining industry use

Natural gas-powered rigs release about 50 percent fewer emissions into the air than do diesel rigs, and are cheaper to operate, Schopp said.

Diesel fuel can cost up to $5,000 a day for a rig, and natural gas about $1,500, he said.

“We can save more than $3,000 a day on fuel. We love it, we think it’s great,” Schopp said.
