SemGroup Announces New Pipeline to Link Oklahoma and Colorado



    SemGroup, L.P., announced today that Front Range Pipeline, L.L.C.
    will build a crude oil pipeline extending from Colorado's DJ Basin, an
    area well-known for its oil and natural gas reserves, to Cushing,
    Oklahoma. The pipeline is expected to be operational by January 2009.

    "Front Range will build a 12-inch pipeline that is approximately
    550 miles in length," said Kevin Foxx, SemGroup executive vice
    president and chief operating officer. "The Front Range Pipeline will
    originate near Platteville, Colorado, and terminate at SemCrude's
    Cushing terminal."

    SemCrude Pipeline, L.L.C., a wholly owned subsidiary of SemCrude,
    L.P. which is SemGroup's crude oil business segment, is the majority
    owner of Front Range Pipeline. Front Range Pipeline will build and
    operate the system, while Kerr-McGee Oil & Gas Onshore, L.P. (a
    subsidiary of Anadarko Petroleum Corporation (NYSE:APC)) and Noble
    Energy, Inc. (NYSE:NBL) will be anchor shippers on the pipeline.

    Foxx said, "Front Range will provide DJ Basin producers direct
    access into the Cushing market and to refiners in the Mid-Continent
    area. It will help producers have uninterrupted flow capacities and
    receive maximum value for their crude oil."

    SemCrude owns more than 4.3 million barrels of crude oil storage
    in Cushing and has additional tanks under construction there. Cushing
    is the site of the largest crude oil trading hub in the United States
    and is the designated delivery point for New York Mercantile Exchange
