August saw ONEOK announce plans to develop two major projects in the Permian's Delaware Basin: the Bighorn Natural Gas Processing Plant in Mentone, Texas, which could begin construction as early as next summer; and the 450-mile Eiger Express Pipeline, which will carry natural gas produced in the Delaware from a new compressor station in Andrews, Texas, to an area near Katy, Texas, which will provide access to Gulf Coast markets and export facilities.
Subscribers to Industrial Info's Global Market Intelligence (GMI) Oil & Gas Project and Plant databases can learn more about these developments--including capacities, investment values and necessary equipment--from detailed project reports on the Bighorn plant, Eiger Express Pipeline and Andrews compressor station.
The Eiger Express Pipeline is being developed in a joint venture with Enbridge Incorporated (Calgary, Alberta), which confirmed its participation in September. For more information, see September 3, 2025, article - Enbridge to Carry More Gas Away from Permian.
By the Numbers
Among its other projects in the area, ONEOK is seeking permits for its 155-mile Saguaro Connector Pipeline, which is designed to carry up to 2.8 billion cubic feet per day of gas from the Waha Hub in Pecos County to facilities in Hudspeth County, some of which will send gas across the border to Mexico. The line will be supported by compressor stations in Coyanosa, which is near the origination point, and near Van Horn, which is about 40 miles east of the Mexico border.

Outside the Permian, ONEOK's joint ventures include the Bison Pipeline in North Dakota's Bakken Shale, which ONEOK owns 50:50 with TC Energy (Calgary, Alberta). The partners are at work on the Bison Xpress Project, a series of compressor station additions and modifications that are designed to elevate gas capacity on the network from 420 million to 430 million cubic feet per day. Subscribers can learn more from a list of detailed project reports.
ONEOK's net income for third-quarter 2025 was reported to be $940 million, a 35.6% increase from third-quarter 2024. Revenues totaled $8.6 billion, a 71.9% increase.

Summary
The pipeline company is developing a series of high-value projects across the Delaware Basin, as a long-running series of acquisitions and joint ventures begin to bear fruit.Permian's Delaware Basin Poised for Buildouts
Midstream operator ONEOK Incorporated (Tulsa, Oklahoma) expanded its presence in the Permian Basin in the third quarter of 2025, after it took full ownership of a natural gas gathering and processing network, announced plans to build a gas-processing plant, and entered a joint venture to build another pipeline. Industrial Info is tracking about $8.5 billion worth of active and proposed projects from ONEOK, more than 85% of which is attributed to grassroot projects.August saw ONEOK announce plans to develop two major projects in the Permian's Delaware Basin: the Bighorn Natural Gas Processing Plant in Mentone, Texas, which could begin construction as early as next summer; and the 450-mile Eiger Express Pipeline, which will carry natural gas produced in the Delaware from a new compressor station in Andrews, Texas, to an area near Katy, Texas, which will provide access to Gulf Coast markets and export facilities.

Years of Acquisitions, Joint Ventures are Paying Off
ONEOK's activity in the Delaware Basin follows its $940 million buyout of former partner NGP XI Midstream Holdings' (Dallas, Texas) 49.9% stake in a joint venture, which was completed this summer. The buyout gave ONEOK full ownership of related natural gas gathering and processing facilities in the Delaware Basin.Among its other projects in the area, ONEOK is seeking permits for its 155-mile Saguaro Connector Pipeline, which is designed to carry up to 2.8 billion cubic feet per day of gas from the Waha Hub in Pecos County to facilities in Hudspeth County, some of which will send gas across the border to Mexico.
