NGL Storage

It’s relatively common along the U.S. Gulf Coast to use underground salt domes to store crude oil, natural gas, mixed NGLs and so-called NGL “purity products” like ethane and propane. There are also a handful of salt cavern storage facilities in Kansas, Michigan, New York and Virginia. But in the Rockies and the West Coast states they’re rare as hen’s teeth, one of the few examples being Sawtooth Caverns, a one-of-a-kind facility in Utah that not only stores propane and butanes but also gasoline and diesel. In today’s RBN blog, we discuss Sawtooth Caverns and its increasing role in the sprawling region’s NGL and refined products markets. 

Since the start of the Shale Revolution 15 years ago, U.S. NGL production has increased by an extraordinary 260% to more than 6.5 MMb/d. And it’s not just NGL production that’s up sharply. So are exports of NGL purity products, especially LPG (propane and normal butane) and ethane. All that growth — and the growth that’s still to come — wouldn’t be possible without a seemingly non-stop expansion of NGL-related infrastructure. Everything from gas processing plants and NGL pipelines to salt-dome storage, fractionators and export docks. And much of that infrastructure is in the hands of just a few large midstream companies that over the years have developed “well-to-water” NGL networks that enable their owners to collect multiple fees along the NGL value chain. In today’s RBN blog, we discuss highlights from our new Drill Down Report on NGL networks.

Crude-oil-focused production growth in the Permian is generating increasing volumes of associated gas that need to be processed and mixed NGLs that need to be piped to Mont Belvieu, fractionated and exported. All that suggests the need for still more infrastructure — processing plants, NGL pipelines, fractionators and export facilities — and Enterprise Products Partners, a top-tier NGL midstreamer, recently laid out a multibillion-dollar plan to help Permian producers keep pace. In today’s RBN blog, we discuss the new set of projects Enterprise has in the works. 

Phillips 66 is probably best known for its fleet of complex refineries, but the Houston-based company also is involved in marketing, chemicals and midstream services. In fact, P66 is one of only a handful of midstreamers offering the full range of “well-to-market” or “well-to-water” NGL services — everything from associated-gas gathering systems and gas processing to NGL pipelines, storage, fractionators and export facilities. And P66’s standing among NGL midstream providers has only been enhanced by the recent doubling of its ownership interest in DCP Midstream. In today’s RBN blog, we continue our series on major NGL networks with a look at P66’s NGL-related assets, most of which run from the Rockies, West Texas and South Texas to the NGL hubs in Mont Belvieu and Old Ocean, TX. 

Less than a handful of U.S. midstream companies own and operate extensive NGL networks that do it all: extract mixed NGLs from associated gas at their processing plants, transport that “Y-grade” to their underground salt-cavern storage facilities in Mont Belvieu, fractionate mixed NGLs into so-called “purity products” at their fractionators, then pipe that ethane, LPG and other products either to domestic end-users or to company-owned export docks. Enterprise Products Partners is a member of that select group and, as we discuss in today’s RBN blog, its NGL network — which stretches from Appalachia to the Permian to the Rockies — is the most extensive.

Crude oil production in the Permian continues to grow, gas-to-oil ratios in the basin are on the rise, and a slew of new gas processing plants are coming online, extracting more and more NGLs that need to be transported, fractionated and shipped to end-users. Targa Resources, with its full slate of NGL-related assets — gathering systems, processing plants, NGL pipelines, fractionators and an LPG terminal — is a big winner in all this. In today’s RBN blog, we continue our series on the U.S.’s robust and growing NGL networks with a look at Targa’s array of assets in the Permian and other production areas.

Natural gas and NGL production growth in the Marcellus/Utica slowed and then leveled off in the early 2020s, largely due to gas-pipeline takeaway constraints. Still, the Northeast remains a key supplier of natural gas and NGL “purity products,” and Energy Transfer’s NGL pipelines and Philadelphia-area marine terminal continue to play critical roles in balancing the region’s ethane and LPG markets. In today’s RBN blog, we continue our series on the U.S.’s robust-and-growing networks of NGL pipelines, fractionators and export terminals, this time with a look at Energy Transfer’s Mariner West and Mariner East pipeline systems and the company’s Marcus Hook terminal.

U.S. production of natural gas liquids and NGL “purity products” continues to rise (aside from occasional hiccups) and domestic demand for the commodities remains flat, so — you know what’s coming — the vast majority of incremental output of ethane, LPG and natural gasoline is headed for export docks. That’s good news, and so is the fact that the midstream sector has the infrastructure in place — or under development — to handle the increasing volumes of NGLs coming their way. In today’s RBN blog, we begin a series on the U.S.’s robust-and-growing networks of NGL pipelines, fractionators and export terminals, starting with a look at Energy Transfer’s “well-to-water” system for NGL gathering, processing, transportation, fractionation, storage and shipment in Texas.

Yet again, the Texas-Louisiana coast is bracing for a hurricane that has the potential to be really bad, not just for the people and homes in the storm’s path, but for the region’s all-important energy sector. Hurricane Laura will be crossing a swath of the Gulf of Mexico dotted with oil and gas production platforms, and is headed for an area chockablock with tank farms, refineries, and steam crackers, as well as export terminals of every stripe: crude oil, refined products, ethane, LPG, and LNG. There’s a good chance there’ll be a lot of disruption to many energy-related activities for at least the balance of this week — and maybe longer — but one of the biggest hits could come to Mont Belvieu, TX, the center of NGL storage and fractionation. Today, we discuss how the storm might affect not only storage at the U.S.’s largest NGL hub, but gas-processing activity hundreds of miles inland.
