Midcontinent Express Pipeline LLC owns and operates an interstate natural gas transmission system of roughly 500 miles running from Bennington in southeastern Oklahoma, across northeast Texas, northern Louisiana and central Mississippi, to an interconnection with the Transcontinental Gas Pipe Line system near Butler, Alabama. The line uses 30, 36 and 42 inch pipe with four compressor stations and interconnects with more than a dozen other interstate pipelines, moving gas from the Barnett Shale, the Fayetteville Shale and the Woodford Shale toward Midwest, Northeast, Mid-Atlantic and Southeast markets. It is a 50/50 joint venture between Kinder Morgan and Energy Transfer, with Kinder Morgan responsible for construction and day to day operation. FERC approved the project in 2007, construction began in September 2008 and the pipeline entered service in August 2009.

Midcontinent Express Pipeline LLC (MEP) files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Global Energy Monitor: Midcontinent Express Gas Pipeline, Energy Transfer: Midcontinent Express Pipeline Announces Additional Significant Capacity Commitment and Offshore Technology: MidContinent Express Pipeline (MEP), Oklahoma. The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Midcontinent Express Pipeline LLC (MEP) where a holder stated one, and are missing where no holder did.
