Chesapeake Energy has joined the growing list of US shale gas producers converting drilling rigs to run on LNG.
The sector big-hitter said it is gearing up to convert 40 Nomac drilling units to run on the fuel by the year-end.
The Oklahoma City-based company also hopes to have 1500 light-duty and 400 heavy-duty vehicles running on LNG by that date.
“These conversions will not only lower our environmental footprint, they will also save the company an estimated $250 million annually once fully implemented,” Chesapeake said in a securities filing.
