Williams Partners LP, the third- biggest U.S. pipeline partnership, agreed to buy a natural-gas pipeline system in the Marcellus Shale from closely held Caiman Energy LLC for $2.5 billion in cash and equity.
Carlyle Group, the Washington-based private-equity firm that went public this year, is taking over operations of a Sunoco Inc. refinery on a bet that revived U.S. oil and natural-gas output can restore to profit the oldest continually operating refinery on the U.S. East Coast.
Kinder Morgan Energy Partners LP, the second-biggest U.S. pipeline operator, said it will decide by the end of March whether to move ahead with a $3.8 billion expansion of its Trans Mountain oil-sands pipeline after receiving ample interest from shippers.
Kinder Morgan Inc., which this year will become the largest U.S. pipeline company after its $20.7 billion purchase of El Paso Corp., aims to extend its lead over competitors in transporting oil across Canada for export to higher-paying markets in Asia.
Kinder Morgan Inc. may reap more than $900 million if it has to sell natural-gas pipelines in the Rocky Mountains to secure federal approval of its $21 billion acquisition of El Paso Corp., scheduled to close in the second quarter.
