• In August 2025, WhiteWater announced that it, together with MPLX LP, ONEOK, and Enbridge through their Matterhorn joint venture, had made a final investment decision to move ahead with the construction of the Eiger Express Pipeline, securing long-term commitments for up to 2.5 billion cubic feet per day of natural gas transport from the Permian Basin to the Katy area.
