Interest conditions: Occidental Petroleum is the general-partner owner and largest customer; for 2025, excluding equity investments, Occidental accounted for 60% of total revenues and other, 36% of natural-gas throughput, 91% of crude-oil and NGLs throughput and 61% of produced-water throughput; 97% of wellhead natural-gas volume and 100% of crude-oil and produced-water throughput were serviced under fee-based contracts; volumetric risk is mitigated through minimum-volume commitments with deficiency payments and cost-of-service contract structures

Description

As at 31 December 2025

Midstream master limited partnership gathering, compressing, treating, processing and transporting natural gas; gathering, stabilizing and transporting condensate, NGLs and crude oil; and gathering, transporting, recycling, treating, supplying and disposing of produced water. The portfolio comprises 16 gathering systems, 46 treating facilities, 31 processing plants and trains, 8 produced-water systems and 18 pipelines across Texas, New Mexico, Colorado, Utah and Wyoming, totalling 14,910 miles of pipeline. Operations are managed as a single operating segment. In the fourth quarter of 2025 the partnership closed the $2.0 billion acquisition of Aris by merger, adding produced-water infrastructure in Lea and Eddy Counties, New Mexico and West Texas. A substantial majority of cash flows are protected from direct commodity-price exposure through fee-based contracts. The partnership also discloses a per-unit gross average NGLs sales price of $25.48/Bbl for 2025 and $28.62/Bbl for 2024; it handles no NGLs volume of its own, so the figure is carried here rather than as a tagged row.
