The Eiger Express Pipeline is a significant addition to the Matterhorn joint venture's portfolio, which already includes the Matterhorn Express Pipeline. The joint venture is owned by WhiteWater (65%), ONEOK (15%), MPLX (10%), and Enbridge (10%). ONEOK and MPLX's direct ownership interests in the Eiger Express Pipeline are incremental to their ownership through the Matterhorn JV, resulting in 25.5% and 22% ownership in the pipeline, respectively [1].
The pipeline will be constructed and operated by WhiteWater and is expected to facilitate the transportation of natural gas sourced from multiple connections in the Permian Basin, including gas processing facilities in the Midland Basin and the Delaware Basin via the Agua Blanca Pipeline, a joint venture between WhiteWater, Enbridge, and MPLX [1].
The strategic location of the Eiger Express Pipeline aligns with the growing demand for natural gas in the Gulf Coast region. This infrastructure development is likely to enhance the efficiency and reliability of natural gas supply chains, contributing to the energy security and economic growth of the region.
The project underscores the commitment of the participating companies to investing in critical infrastructure that supports the energy sector. The involvement of leading energy infrastructure companies such as ONEOK, MPLX, and Enbridge, along with WhiteWater, suggests a collaborative effort to leverage their combined expertise and resources to deliver a robust natural gas transportation solution.
The expected timeline for the project's completion is mid-2028, indicating a substantial investment in the future of natural gas infrastructure. This investment is likely to have positive implications for the participating companies' financial performance and market position, particularly in the midstream energy sector.
