Saddlehorn Pipeline Company, LLC holds an undivided joint interest in a crude oil pipeline of roughly 600 miles that carries barrels from the Denver-Julesburg Basin and the wider Rocky Mountain region to storage tanks at the Cushing, Oklahoma trading hub, with transport capacity of up to 290,000 barrels a day. The line entered service in 2016 running from Platteville, Colorado to Cushing, was extended north to a new origin point at Carr, Colorado, and shares pipe with the neighbouring Grand Mesa system under a combined arrangement agreed by the two projects. Its northern segment gathers from Colorado and Wyoming production and it is used by shippers under long term transportation contracts. ONEOK acts as operator under an agreement that reimburses it for management services and operating costs, alongside partners including Plains All American Pipeline, Western Midstream and Chevron.

Saddlehorn Pipeline Company, 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 ONEOK, Inc. Form 10-K for 2025 (SEC EDGAR), Saddlehorn and Grand Mesa to Combine Projects through Undivided Joint Interest in DJ Basin Crude Oil Pipeline (PR Newswire), Saddlehorn Oil Pipeline (Global Energy Monitor) and Saddlehorn Pipeline from Platteville to Cushing is Operational (Oklahoma Energy Today). 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.
- ONEOK, Inc., as of 31 Dec 2025. Equity-method LLC interest, not denominated in shares, so shares is null. FY2025 10-K Note N investments table: 'Saddlehorn 40% $361 $373' (2025 and 2024 carrying value in millions). Q2 2026 10-Q Note H confirms the 40% owned joint venture with equity in net earnings of $11 million (Q2 2026) and $22 million (six months) but no restated Q2 2026 carrying value, so the FY2025 figure is used. source
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 Saddlehorn Pipeline Company, LLC where a holder stated one, and are missing where no holder did.
