Inside the largest refiner merger of all time is a hidden pipeline grab.

Andeavor purchased a 25 percent stakeBloomberg Terminal last week in Phillips 66 Partners LP’s Gray Oak pipeline, which will haul Permian shale oil to the U.S. Gulf Coast starting in the end of next year. The integrated refining company also owns oil gathering assets in the world’s most attractive shale basin.
