MPLX’s July 31 announcement that it has reached an agreement to acquire Northwind Midstream for $2.375 billion puts a spotlight on two undeniable trends. First, the acquisition is the latest in what by now is a long series of multibillion-dollar deals by midstream giants to expand their Permian-to-Gulf, “wellhead-to-water” networks that gather, process, transport and export crude oil, natural gas and/or NGLs. Second, Northwind has been a pioneer in gathering and processing unusually sour associated gas in the prolific Northern Delaware Basin, an area of particular interest to a growing number of E&Ps. In today’s RBN blog, we discuss the deal and what it brings to MPLX.
It finally happened. And it’s a very big deal for MPLX and ONEOK, both of which have been working for years to become full-fledged members of the elite “NGL wellhead-to-water club.” But the companies’ announcements that MPLX will build two fractionators at the terminus of a new NGL pipeline from Sweeny to Texas City and that ONEOK and MPLX will joint build a new LPG export terminal nearby (and a new purity-product pipeline between Mont Belvieu and the terminal) doesn’t just fill in the missing pieces of the puzzle they’ve been assembling. The plans also will give Gulf Coast LPG exporters the additional capacity they desperately need and — no small thing — create another fractionation hub. In today’s RBN blog, we discuss what MPLX and ONEOK are planning and why it matters.

Natural gas production in the Permian is still on a roll — increasing so fast that midstream infrastructure can barely keep up. But producers, marketers and shippers want more than new takeaway capacity. They also need to know that the pipeline systems they sign up with can reliably move their gas to markets where they can get the best price. Put simply, they are demanding optionality. In today’s RBN blog, we discuss the optionality provided by a WhiteWater Midstream-led joint venture’s (JV) expanding gas pipeline network in Texas, including a brand-new project between the Agua Dulce and Katy gas hubs that’s in the works.
Energy Transfer’s plan to buy WTG Midstream, a West Texas-based and private equity-backed natural gas gatherer and processor, just got a bit less expensive — and not quite so comprehensive. Energy Transfer will still acquire WTG’s network of more than 6,000 miles of gas pipelines, eight processing plants and more, but WTG’s 20% stake in the joint-venture (JV) BANGL pipeline system is no longer part of the deal. In today’s RBN blog, we’ll take a look at the detour from the original transaction.
The U.S. may be in a monthslong pause in approving new LNG exports but that doesn’t change the fact that U.S. LNG export capacity will nearly double over the next four years, that most of the new liquefaction plants are being built along the Texas coast, and that their primary source of natural gas will be the Permian Basin. That helps to explain why three big midstream players — WhiteWater/I Squared, MPLX and Enbridge — recently formed a joint venture (JV) to develop, build, own and operate gas pipeline and storage assets that link the Permian to existing and planned LNG export terminals. In today’s RBN blog, we examine the new JV and discuss the ongoing development of midstream networks for crude oil, natural gas and NGLs.
Infrastructure constraints in the energy sector come in all shapes and sizes, and don’t think for a second that they only involve pipelines. For many producers of crude oil, refined products and other liquids, the Mississippi River is a critically important conduit for barging commodities to market. Lately though, water levels on sections of the river have been near historic lows, reducing both the volume of liquids that each barge can carry and the number of barges the Mississippi can handle. Among other things, the low water situation has been putting a squeeze on condensate producers in the “wet” Marcellus/Utica, who depend on barges to transport a significant portion of their superlight crude oil down the Ohio and Mississippi rivers to refineries and for blending into Light Louisiana Sweet (LLS). In today’s RBN blog, we discuss the situation.
Over the past two years, MPLX has been ramping up its midstream development activity in the Lone Star State, or more specifically in the “Permian-to-Gulf” market, where it’s been building or buying into gathering systems, gas processing plants, and crude and natural gas takeaway pipelines, among other things. Marathon Petroleum Corp.’s midstream-focused master limited partnership also has been in hot pursuit of a number of possible NGL-related projects, including MPLX’s proposed Belvieu Alternative NGL (BANGL) Pipeline and three big fractionation plants in the Sweeny, TX, area, and a planned LPG export terminal in Texas City, TX. As a group, these projects would require millions of barrels of underground salt-cavern storage capacity for y-grade and NGL purity products along the Texas coast, as well as multiple pipeline connections to move the stuff to where it needs to be. Today, we continue our series on Gulf Coast NGL storage with a look at the NGL side of the MLP’s Permian-to-Gulf strategy.
