Crude slate

US-advantaged (Permian/Eagle Ford) domestic crude via Gray Oak plus foreign crude oil via the Freeport deepwater terminal.

Crude in & products out

From refinery research; each row links its source.

DirectionModeRoutePoint / originProductsSource
crude in marine Freeport Harbor / Brazos River Channel
Sweeny receives crude primarily through wholly/jointly owned Gulf Coast terminals including a deepwater terminal at Freeport, Texas.		 Waterborne imports and US-advantaged crude crude source
crude in pipeline Gray Oak Pipeline
Phillips 66 Partners built Gray Oak specifically to move Permian/Eagle Ford crude to Gulf Coast destinations 'including the Sweeny Refinery and the Houston market'; began operating late 2019, full service by mid-2020. Not currently listed as a graph edge for this refinery -- worth adding.		 Permian Basin and Eagle Ford Shale crude source
products out pipeline Sweeny to Pasadena Pipeline
This 12-inch, ~294,000-bpd line runs FROM the Sweeny refinery TO the Pasadena terminal -- it is the refinery's primary outbound products route, not an inbound one. Also carries pentanes-plus.		 Pasadena products terminal, Harris County, TX gasoline distillate ngl source
products out pipeline Colonial Pipeline
Likely reached indirectly through the Sweeny-to-Pasadena pipeline's injection into the Pasadena hub rather than a direct refinery-gate Colonial connection; not separately confirmed by name within budget.		 Pasadena (via Sweeny-to-Pasadena pipeline interconnect) gasoline distillate inferred
products out marine Freeport Harbor
Phillips 66's Freeport LPG Export Terminal is built at the site of its existing Freeport marine terminal.		 Refinery/company marine terminal, Freeport, TX lpg refined products source
products out truck rack Phillips 66 Company - Sweeny
Refinery-direct truck rack; self-evident for an operating refinery of this scale.		 Refinery site gasoline distillate source

Rates are pipeline line-haul transcribed from published FERC tariffs; every figure cites its tariff and item. Cost to serve (netback) adds origin spot price and destination fees. "Confirmed" links match a tariff delivery point to the facility; "same city" means the point is in the facility's city — plausible, not proof; "per research" means the facility's research profile names the pipeline as an outlet.
