Last year, a Bloomberg report warned that key Permian-to-Corpus oil pipelines were nearly filled to capacity, “threatening to cap U.S. oil exports at a time when the world needs more.” Meanwhile, outflowing from Permian to Houston has steadily increased since late 2020, specifically with the addition of both the Enterprise M2E3 pipeline emanating from Midland, and the Wink to Webster pipeline.

Phillips 66 and Kinder Morgan on Monday began soliciting shipper commitments for a proposed pipeline system that will move fuel from the Texas refining hub to bolster supplies in Arizona and California as a spate of refinery closures stokes supply concerns.

Construction will soon begin on a 450-mile pipeline connecting critical natural gas sources from the Permian Basin in West Texas to the Katy area in the Gulf Coast region of the state. It’s called the Eiger Express Pipeline. WhiteWater Midstream, an oil-and-gas company out
of Austin, is partnering on the pipeline through their Matterhorn partnership with affiliates of Tulsa, Okla.-based natural gas company ONEOK and MPLX—a part of Marathon Petroleum Corporation out of Ohio. When fully operational, the Eiger Express should be able to transport up to 2.5 billion cubic feet of natural gas per day. The 450-mile pipeline will measure 42 inches in diameter. While it shies well behind the longest pipelines in the U.S. (for comparison sake, the Rockies Express pipeline that connects Colorado to Ohio measures 1,679 miles), the Eiger Express is positioned to help clear up what’s become a bottleneck between the Permian Basin and Gulf Coast. Expected completion is summer of 2028.

Matterhorn Express line, a joint venture between WhiteWater and MPLX, plus EnLink Midstream (now part of ONEOK) and Devon Energy of Oklahoma is helping to ease the flow of gas from West Texas to the Houston area. Midland-based Tall City Exploration CEO Mike Oestmann said, “We produced a lot of gas that we not only didn’t get paid for, we paid for it to be taken away.” The Matterhorn Express Pipeline is now fully subscribed after several Permian Basin producers expanded their transportation agreements in the first quarter of 2025, according to a recent report by East Daley Analytics. With principals announcing an agreement on a final investment, construction will soon begin on a 450-mile pipeline connecting critical natural gas sources from the Permian Basin in West Texas to the Katy area in the Gulf Coast region of the state.

Targa Resources has announced plans for a new 30 inch natural gas liquids pipeline running 500 miles from the Permian Basin to Mont Belvieu. The Speedway NGL Pipeline will transport NGLs from Targa’s existing Permian Basin assets and future additions to the company’s fractionation and storage complex in Mont Belvieu. Initial capacity is 500,000 barrels per day and expandable to 1 million barrels per day.
The pipeline is expected to begin service in the third quarter of 2027 at a cost of $1.6 billion. The project coincides with Targa’s construction of the Yeti processing plant, with a 275 million cubic feet per day capacity to serve growth on Targa’s Permian Delaware system. Including Yeti, Targa is constructing five gas processing plants that will come online over the next two years, with an aggregate inlet capacity of 1.4 billion cubic feet per day and estimated NGL production of about 175,000 to 200,000 barrels per day. Targa also announced a new 35-mile natural gas pipeline that will enhance connectivity across several Targa plants in the Permian Midland and a 55-mile conversion of an existing Targa pipeline into natural gas service, together known as Buffalo Run, which will connect Targa’s Midland and Delaware intra-basin natural gas systems.
