Delta Air Lines subsidiary Monroe Energy LLC entered into a five-year agreement with Bridger LLC to supply 65,000 barrels per day of domestic crude oil to its Trainer, Pa., refinery. The agreement will supply about one-third of the crude oil refined daily at the Trainer facility and is a major step in Delta’s strategy to manage its jet fuel costs.

“By combining this transaction with our other sources of domestic crude supply, we expect to meet our goal of a minimum of 70,000 barrels per day of domestic crude sourcing at the refinery,” said Graeme J. Burnett, Monroe chairman and senior vice president—fuel optimization for Delta. “Supplying a third of the crude refined at Trainer from the Bakken further reduces the overall cost of fuel for Delta, adding to the significant benefits we already see from Monroe Energy, in combination with our robust fuel hedging program, fleet efficiency improvements and fuel conservation efforts.”

Bridger recently invested $200 million in the acquisition of 1,300 new railcars to add to its existing railcar fleet. The railcars will be among the assets Bridger uses to transport domestic oil from the Bakken to the Trainer refinery.
