## Crude supply
- marine: Freeport Harbor / Brazos River Channel — Sweeny receives crude primarily through wholly/jointly owned Gulf Coast terminals including a deepwater terminal at Freeport, Texas.
- 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.

## Product outlets
- 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.
- 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.
- marine: Freeport Harbor — Phillips 66's Freeport LPG Export Terminal is built at the site of its existing Freeport marine terminal.
- truck_rack: Phillips 66 Company - Sweeny — Refinery-direct truck rack; self-evident for an operating refinery of this scale.

## Recent events
