Liquid Cavern Storage Benchmarking
Deep visibility into NGL inventory levels, NGL hub dynamics, and storage economics across NGL hubs in Mont Belvieu and other locations in Gulf Coast
Report Frequency: Annual (March)
NGL storage is the critical link between Y-grade production and volatility in fractionation and downstream export and petrochemical markets. From Mont Belvieu’s vast underground salt cavern complex to Conway’s purity product tanks and caverns in Louisiana, storage availability and utilization directly influence NGL prices, fractionation scheduling, and export timing. Enkon’s NGLs Storage product provides an integrated, hub-level benchmarking of product inventory, cavern level capacity, brine pond capacity and commercial dynamics across the full NGL product slate — ethane, propane, normal butane, isobutane, and natural gasoline as well as refined products. Our analysis connects the upstream production picture to downstream petrochemical and export demand, helping clients anticipate inventory builds and draws before they move the market.
❓Who is this for?
NGL storage market is as opaque as it can get. NGL storage doesn’t operate in isolation — it reflects the balance between wellhead supply, fractionation output, domestic demand, and export flows. Our NGLs Storage product is explicitly designed to connect those dots, giving you early signals on tightening or oversupplied conditions.
📔Key Deliverables and Features
▸ Cavern-level inventory monitoring — working storage levels at Mont Belvieu, Sweeny, Stratton Ridge and 15 other NGL cavern hubs across the U.S. Gulf Coast
▸ Purity product storage tracking — individual NGL component inventory and capacity by hub and product
▸ Brine Pond capacity database — facility-level capacity, brine-to capacity ratios and ownership data
▸ Injection/withdrawal trend analysis by cavern — seasonal and event-driven storage activity patterns
▸ Inventory vs. demand correlation — propane heating season draws, ethane cracking demand, and butane blending cycles
▸ Price-storage relationship modeling — identifying inventory inflection points and their historical price implications
▸ Export terminal pre-positioning analysis — linkage between storage builds and LPG vessel loading activity at Gulf Coast ports
