Natural Gas Processing Inlet Volume measures physical unprocessed rich gas entering operated processing facilities or measured near the wellhead under Enterprise's methodology.

Enterprise Products Partners reported 7.906 billion cubic feet per day in 2025.

Fee-based processing leaves about 0.595 Bcf per day outside that classification

Enterprise reported Fee-Based Natural Gas Processing Volume of 7.311 billion cubic feet per day.

Subtracting 7.311 from 7.906 leaves about 0.595 Bcf per day. Fee-based volume is therefore about 92.5% of the inlet-volume figure.

The ratio is a classification scale check, not a contract reconciliation

Inlet volume is a physical-flow measure. Fee-based processing volume is an economic/contract classification.

The two can differ because of measurement points, mixed arrangements, plant scope, and other issuer-specific methodology. The residual should not automatically be labeled commodity-based processing.

Inlet gas is not downstream product output

Processing separates rich gas into residue gas and NGL components. The inlet figure therefore should not be added to Equity NGL-Equivalent Production Volume or NGL fractionation volume as though they were parallel quantities.

Where this concept fits

Gas processing and NGL conversionCurrent relationship
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.

Pipeline, terminal, and storage network
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.

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.
