Blue Racer Midstream gathers and processes natural gas in the Utica Shale of eastern Ohio and the wet gas window of the Marcellus in the West Virginia panhandle, taking raw gas from wellheads through compression, dehydration and treating, then cryogenic processing to strip out natural gas liquids, fractionation into ethane, propane and heavier products, and pipeline transport of the resulting liquids and condensate. Its two main plants are the Natrium complex in Marshall County, West Virginia and the Berne complex in Monroe County, Ohio, each with about 400 million cubic feet a day of cryogenic processing capacity, connected by natural gas liquids and condensate lines, with Natrium also housing roughly 120,000 barrels a day of fractionation. The business was formed in December 2012 by Dominion, which contributed existing midstream assets, and Caiman Energy II, which contributed capital; Dominion sold out to First Reserve in 2018.

Blue Racer Midstream LLC 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 Williams Partners L.P. Form 10-K for 2017 (SEC), Dominion, Caiman Energy II To Form Blue Racer Midstream (MarketScreener report of the Williams announcement) and First Reserve Announces Agreement To Acquire Dominion Energy's 50% Interest In Blue Racer Midstream (PR Newswire). 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 Blue Racer Midstream LLC where a holder stated one, and are missing where no holder did.
