New fractionation plants, steam crackers and export facilities are being built along the Gulf Coast, all spurred by rising U.S. production of natural gas liquids. This incremental NGL output and these new projects are putting serious pressure on existing NGL pipeline and storage infrastructure, and prodding the development of new salt-cavern storage capacity for mixed NGLs, NGL purity products, and ethylene and other olefins. Also, new, expanded and repurposed pipelines to enhance NGL-related flows throughout the region are in the works. Today, we continue our series on NGL storage facilities along the Gulf Coast with a look at Easton Energy Services’ plans for more underground storage capacity in Markham, TX, and new NGL and olefin pipelines.

A build-out of NGL fractionators, steam crackers and export terminals for ethane, LPG and ethylene is actively in progress along the Gulf. This growth is spurring the development of new storage capacity — not just at the Mont Belvieu NGL hub, but in other, nearby areas with access to fracs, crackers and export docks. Much of this new storage capacity is being developed by companies that fractionate mixed NGLs and sell so-called “purity products” to meet their internal needs. However, at least one project is being built by what you might call an “independent,” whose aim is to connect to multiple pipelines and provide storage services to customers, without taking title to products alongside their customers. Today, we continue our series on existing and planned NGL storage facilities along the Gulf Coast with a look at Caliche Development Partners’ new storage complex in Beaumont, TX.

Rising U.S. production of NGLs and so-called “purity products” like ethane and propane, as well as growth in steam cracker capacity and NGL and ethylene exports, are giving added importance to NGL and ethylene storage capacity in underground salt caverns along the Gulf Coast. Mont Belvieu, TX, has long been the epicenter of both fractionation and salt-cavern NGL storage — and it will remain so — but there are other areas along the Texas coast with frac capacity and NGL storage, as well as steam crackers and export docks. The questions now are, is there enough in the right locations, and can what’s stored there be received and quickly sent out? Today, we begin a look at existing and planned NGL storage facilities along the Texas coast that are not in Mont Belvieu.

Storage, the great balancing mechanism of the natural gas market in North America is heading toward another evolution in its usage, flow patterns and economics.  Not too many years ago, natural gas storage was the hottest midstream investment opportunity going, expected to synchronize inbound flotillas of LNG imports with seasonal domestic demand.  Winter vs. summer price differentials were wide, prices were volatile and storage economics looked great.  When shale gas happened, those differentials evaporated along with storage economics.  Today another phase looms for natural gas storage as Marcellus and now Utica production ramp up on top of (or more accurately, underneath) the largest storage region in the world – the Northeast U.S.  This is a big topic with big implications.  So rather than jumping into the middle of the upcoming gas storage transformation, we will walk through a multi-part North America natural gas storage blog series -  its history and status, its challenges, who’s involved, and finally what could be in store going forward.  Today we’ll start with some natural gas storage basics.

We’ve talked a lot here about NGL storage in Mont Belvieu and Conway.  Those are the big underground storage caverns washed out of salt formations thousands of feet below the surface.  But those are not the only places where NGLs are stored in underground salt caverns.  Two important facilities, especially for West Coast NGL markets are located in the seemingly unlikely locations of Bumstead, AZ and Adamana, AZ.  Today and in a later follow up we’ll look at why these facilities are in Arizona, how they got there, and the unique niche they fill in the NGL marketplace.
