Gulf Coast Fractionators runs a natural gas liquids fractionation plant at Mont Belvieu, Texas, the main NGL hub on the United States Gulf Coast, where it splits the mixed liquids stream that comes off gas processing plants into purity products such as ethane, propane, normal butane, isobutane and natural gasoline for petrochemical and fuel buyers. The plant was expanded in 2010 by about 42 percent, or 43,000 barrels per day, and is rated at roughly 135,000 to 145,000 barrels per day. It is a partnership of midstream and refining companies: Targa Resources and EnLink Midstream each hold 38.75 percent and Phillips 66 holds 22.5 percent, the Phillips interest descending from ConocoPhillips, an original partner alongside Devon Energy. The facility was shut down in the first half of 2021 and the partners spent roughly 67 million dollars to bring it back, restarting it in 2024 into a Gulf Coast fractionation market that was running full.

Gulf Coast Fractionators (GCF) 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 Gulf Coast Fractionators Expands NGL Facility (Pipeline and Gas Journal, November 2010), Timing is Everything for GC Frac Restart (East Daley Analytics) and Gulf Coast Fractionators Announces Expansion of Its Natural Gas Liquids Fractionation Facility (Targa Resources). 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 Gulf Coast Fractionators (GCF) where a holder stated one, and are missing where no holder did.
