Fractionate Permian Basin mixed NGLs at Mont Belvieu into export-grade propane and butane, then move those products by direct pipeline to Galveston Bay vessels.
Permian Basin producers deliver mixed NGL streams that cannot be exported in raw form, so those streams must reach Mont Belvieu fractionation trains before any export movement is possible — making fractionation capacity the ceiling that governs throughput across the entire chain. Each additional train at Mont Belvieu draws on shared utilities and existing pipeline interconnections already in place, so incremental volume can be processed at lower per-unit cost, but that economy is site-specific and cannot be reproduced elsewhere without constructing entirely independent infrastructure. Long-term supply agreements binding upstream producers to Mont Belvieu delivery and export contracts locking customers to specific Galveston Bay berths reinforce that site dependency contractually, so the physical and commercial structures of the system mutually constrain each other. The direct pipeline connecting Mont Belvieu to those berths then concentrates the entire chain's exposure into a fixed marine exit point, where hurricane damage, channel restriction, or vessel congestion arrests outflow regardless of how much fractionation capacity is running.
How does this company make money?
The company earns processing payments for fractionating mixed NGLs into separate specification-grade products, captures the difference between NGL purchase and sale prices on volumes it buys and resells, and collects loading payments from LPG export vessels using the Galveston Bay marine terminal berths.
What makes this company hard to replace?
Three specific mechanisms make switching away from this infrastructure difficult. Long-term NGL supply agreements with Permian Basin producers specify delivery to Mont Belvieu facilities, binding upstream flows contractually. LPG export customer contracts require loading at specific Galveston Bay berths, locking the downstream end in place. Pipeline interconnection agreements at Mont Belvieu tie multiple parties into the existing complex in ways that cannot be quickly reproduced at an alternative location.
What limits this company?
Mont Belvieu fractionation train capacity sets the ceiling on how much mixed NGL the system can absorb and convert. That ceiling cannot be raised quickly because new trains require multi-year construction timelines and contiguous land adjacent to existing pipeline interconnections — both of which are physically constrained at the site.
What does this company depend on?
The system depends on five specific upstream inputs: Permian Basin wellhead natural gas production; mixed NGL pipeline capacity from West Texas processing plants that carries those streams eastward; Mont Belvieu fractionation plant operations to separate them into usable products; Galveston Bay marine terminal berth access for export loading; and LPG vessel scheduling that determines when and how quickly finished product leaves the terminal.
Who depends on this company?
Three groups rely directly on this infrastructure. Petrochemical plants on the Texas Gulf Coast depend on ethane feedstock deliveries from the fractionation process; interruption cuts their manufacturing input. International LPG buyers whose propane import schedules are built around Galveston Bay loading windows are exposed whenever berth or channel access is constrained. Permian Basin producers depend on NGL takeaway capacity through this system as part of the economics of their drilling programs; if takeaway is unavailable, their production economics deteriorate.
How does this company scale?
Additional fractionation trains at Mont Belvieu can process incremental mixed NGL volumes at lower per-unit cost by drawing on shared utilities and existing pipeline interconnections already in place. Expanding beyond Mont Belvieu, however, requires constructing entirely new fractionation complexes with separate pipeline connections and independent marine access, none of which can draw on the infrastructure economies that exist at the current site.
What external forces can significantly affect this company?
U.S. petrochemical plant construction rates influence domestic demand for ethane, one of the products the fractionation process separates out. Asian LPG import demand — driven by heating seasons and petrochemical feedstock cycles — shapes how much propane and butane the export terminals need to move. Federal permitting timelines for new pipeline routes crossing multiple states affect the pace at which any expansion of upstream NGL delivery capacity can be built.
Where is this company structurally vulnerable?
Because the export chain terminates at a fixed set of Galveston Bay berths connected by that same direct pipeline, any disruption at the marine terminal — hurricane damage, channel depth restriction, or vessel traffic congestion — arrests product outflow regardless of how much fractionation capacity is running, converting the integration advantage into a single physical point of failure.
Supply Chain
Liquefied Natural Gas Supply Chain
The LNG supply chain moves natural gas from producing regions to importing countries by cooling it to -162°C for ocean transport, then reheating it for distribution through domestic pipeline networks to heat homes, generate electricity, and fuel industrial processes. The system is governed by three root constraints: liquefaction infrastructure that costs $10-20 billion per facility and takes five to seven years to build, regasification dependency that prevents importing countries from receiving LNG without their own terminal infrastructure regardless of global supply levels, and long-term contract structures requiring fifteen to twenty-year take-or-pay commitments that lock trade flows into rigid patterns that cannot quickly redirect when geopolitical or market conditions change.
Oil and Gas Supply Chain
The oil and gas supply chain moves crude oil, natural gas, gasoline, diesel, jet fuel, and plastics feedstock from subsurface reservoirs to end consumers through an infrastructure system governed by three root constraints: geological fixity of reserves that cannot be manufactured or relocated, capital cycle lengths of five to ten years that make investment decisions effectively irreversible, and infrastructure lock-in from pipelines, refineries, and terminals that are geographically fixed and take decades to build, producing a system where supply responses lag demand observations by years and physical bottlenecks determine competitive outcomes more than pricing power.
Natural Gas Pipeline Supply Chain
The natural gas pipeline supply chain moves methane from production basins to homes, power plants, and factories through networks of buried steel pipes, compressor stations, and underground storage facilities. The system is governed by three root constraints: infrastructure irreversibility that locks specific producers to specific consumers for decades once a pipeline is built, compressor station physics that make pipeline capacity a function of the entire compression chain rather than pipe diameter alone, and storage geography mismatches where seasonal demand buffering depends on underground facilities whose locations were determined by geology rather than proximity to consumption centers.
