NGL Pipeline Transportation Volume measures NGL volumes transported through Enterprise's pipeline systems.

Enterprise Products Partners reported 4.646 million barrels per day in 2025.

NGLs supplied about 56.2% of aggregate liquids pipeline volume

Enterprise reported Liquids Pipeline Transportation Volume of 8.264 million barrels per day.

Dividing 4.646 by 8.264 gives about 56.2%, making NGLs the largest of the three disclosed liquids pipeline lanes.

Fractionation and marine loading are downstream stages, not additive volume

Enterprise also reported NGL Fractionation Volume of 1.706 million barrels per day and NGL marine terminal volume of 970 thousand barrels per day.

Those measures can involve the same molecules at different points in the system. Adding them to NGL pipeline throughput would double count operating activity rather than produce a unique-barrel total.

Pipeline mix does not equal product margin

The 4.646 million barrel figure measures transportation activity. Tariffs, commitments, asset ownership, route mix, operating costs, and downstream services determine how that activity translates into gross operating margin.

Where this concept fits

Pipeline, terminal, and storage networkCurrent relationship
Commodity-specific pipeline and marine-terminal volumes show throughput by service layer, equivalent pipeline volume provides a network-wide energy-equivalent view, and pipeline mileage plus liquids and gas storage capacity describe the physical footprint that supports those flows.

Gas processing and NGL conversion
Processing inlet volume shows physical rich-gas flow, fee-based processing volume isolates service activity, equity NGL-equivalent production captures commodity-linked processing exposure, and fractionation volume shows the downstream separation of mixed NGLs into purity products.

Petrochemical throughput and margin conversion
Propylene production and petrochemical/refined-products pipeline volumes add manufacturing and specialty-product activity, while gross operating margin shows the issuer-defined non-GAAP operating contribution produced across the integrated network.
