Plains All American Pipeline LP, Marathon Petroleum Corp. and BP Oil Pipeline Co. launched a nonbinding open season for the reversal of the Capline pipeline, which transports crude oil from St. James, La., to Patoka, Ill.

If the Marathon Pipe Line LLC-operated Capline proceeds with the reversal, southbound flow could be operational in the second half of 2022. The pipeline would have an initial capacity of 300,000 barrels per day once reversed and would be able to receive crude oil from connecting carriers at Patoka. Shippers can also access a distribution network at St. James, which includes refineries, terminals, ships, barges and rail.

Marathon Pipe Line is a wholly owned subsidiary of MPLX LP, the master limited partnership sponsored by Marathon Petroleum.

BP Oil Pipeline is a subsidiary of BP plc.
