Permian-to-Gulf Infrastructure

Several large, publicly held midstream companies play critical roles in transporting crude oil, natural gas and NGLs from the Permian Basin to markets along the Gulf Coast, and all of them are investing hundreds of millions or even billions of dollars to expand their Permian-to-Gulf infrastructure. But there’s a privately held outlier among them — WhiteWater Midstream, which has developed key gas pipelines in Texas and has been partnering with MPLX, Enbridge and others to own and develop a few more. In today’s RBN blog, we look at the growing portfolio of WhiteWater and the WPC joint venture (JV) and discuss highlights from our new Drill Down Report on Permian-to-Gulf infrastructure projects. 

A half dozen large midstream companies provide the full gamut of “wellhead-to-water” services for Permian-sourced natural gas and/or NGLs, and a couple of those offer the same for crude oil as well. For Enbridge and Plains All American, the clear focus has been on crude — pipelines, storage and marine terminals — though Enbridge has been rapidly expanding its portfolio of Permian-to-Gulf gas assets too. In today’s RBN blog, we look at what Enbridge and Plains have and what they are planning. 

Crude-oil-focused drilling and completion in the Permian Basin is generating fast-increasing volumes of associated gas — and creating opportunities for midstream companies that provide “wellhead-to-water” services for natural gas and NGLs. ONEOK has become a much bigger player in this space via several transformational acquisitions and MPLX has been making moves of its own. (The companies also are working together on a new LPG export terminal — and more.) In today’s RBN blog, we continue our review of Permian-to-Gulf midstreamers’ expansion plans with a look at what ONEOK and MPLX are up to. 

The handful of midstream companies that provide a full range of “wellhead-to-water” services between the Permian and the Gulf Coast are in growth mode, advancing a long list of gas processing plants, takeaway pipelines, fractionators and export terminal expansions. Last time we looked at what Enterprise Products Partners and Energy Transfer are up to. In today’s RBN blog, we shift our spotlight to what Targa Resources and Phillips 66 are planning, with Targa building a slew of projects and P66 growing primarily through organic opportunities that have arisen following recent bolt-on M&A. 

In their first earnings calls of 2025, the handful of large midstream companies that provide the gamut of “wellhead-to-water” services in Texas laid out plans for yet another round of projects — everything from gas processing plants and takeaway pipelines to fractionators and export terminal expansions. At the same time, many of these same midstreamers expressed a degree of caution about overbuilding. They sought to reassure Wall Street that they were only approving plans underpinned by strong commercial support. In today’s RBN blog, we discuss the latest capital spending plans of this select, upper tier of midstream service providers.
