Spun off from Marathon Oil a year ago, the refiner is looking to capitalize on the renewed interest in pipelines by spinning off its own midstream assets. We've seen a lot of industry players looking to reap the rewards of value held in pipeline business, as Sunoco is being bought by Energy Transfer Partners for its East Coast network of transmission lines, Kinder Morgan is buying El Paso, and ConocoPhillips spun off its midstream and chemical assets into Phillips 66. The refinery industry has seen profits squeezed as demand for gasoline and other petroleum products has declined, down more 10% over the past five years, according to the U.S. Energy Information Administration, as crude prices have risen.
