DENVER -- Duke Energy Field Services (DEFS) has significantly increased its midstream presence in the Gulf of Mexico with the purchase of the former MCN Investment Corporation's ownership interest in Dauphin Island Gathering Partners (DIGP), Mobile Bay Processing Partners (MBPP) and Gulf Coast NGL Pipeline, L.L.C. (Gulf Coast). Terms were not disclosed.

DEFS is the owner and managing partner of DIGP and MBPP and is the managing member of Gulf Coast. With the ownership interest purchase, DEFS' interest in DIGP increased from 37.3 percent to 71.8 percent; in MBPP from 28.8 percent to 57.6 percent; and in Gulf Coast from 28.9 percent to 57.9 percent. The transaction closed on July 11.

DIGP, MBPP and Gulf Coast are integrated midstream facilities designed to gather, transport and process natural gas produced in the Gulf of Mexico off the coasts of Louisiana, Mississippi and Alabama. The natural gas is delivered to interstate natural gas pipelines that serve end user markets and power plants in growing areas throughout the northeastern and southeastern United States. Natural gas liquids extracted from the natural gas stream at MBPP's Coden, Ala., facility are transported to Louisiana fractionation facilities via pipelines partially owned by Gulf Coast.

"This timely acquisition greatly enhances our corporate growth strategy in the eastern Gulf, which is one of the most active offshore exploration and development areas in the Gulf of Mexico," said Mark Borer, senior vice president of DEFS. "The eastern Gulf will be a critical natural gas supply basin for the growing Southeast area power plant markets in Florida, Alabama and Georgia."

"The former MCN Investment Corporation became a DTE Energy asset with the merger of MCN Energy and DTE Energy on May 31," said David E. Meador, DTE Energy senior vice president and chief financial officer. "Divestiture of specific assets such as this are in line with DTE Energy’s effort to divest non-core assets that do not integrate with DTE Energy’s long-term strategy."
