## Crude supply
- pipeline: Seaway Pipeline — Not confirmed specifically for Baytown by a named source; inferred from ExxonMobil's own statement that Baytown crude is supplied 'by pipeline crude primarily from Texas and Canada' and Seaway's role as a primary Cushing-to-Houston-area crude conduit.
- pipeline: Wink to Webster Pipeline — Inferred, not directly confirmed for Baytown; consistent with ExxonMobil's statement that Baytown crude comes 'primarily from Texas' (Permian light sweet).
- marine: Houston Ship Channel — Directly supported: ExxonMobil states Baytown crude is 'supplemented by crude from around the globe, including the Persian Gulf, Africa, South America and Mexico,' and the refinery sits on the Houston Ship Channel.

## Product outlets
- pipeline: Colonial Pipeline — Colonial's documented Texas origin is Pasadena/Houston; Baytown-area refineries are broadly understood industry suppliers into this point, but no single source names Baytown specifically as a Colonial shipper.
- pipeline: Explorer Pipeline — Explorer originates in the Houston area and is a standard outlet for Gulf Coast Houston-area refineries; not specifically confirmed for Baytown by name.
- pipeline: TEPPCO / Enterprise TE Products — Enterprise's legacy TEPPCO products system serves the Houston/Beaumont corridor; not specifically confirmed for Baytown by name.
- marine: Houston Ship Channel — Baytown sits directly on the Houston Ship Channel with deepwater marine terminal access.
- barge: Gulf ICW / Houston Ship Channel — Standard barge distribution mode for HSC-sited refineries; not separately confirmed.
- rack_terminal: Enterprise Morgan's Point Complex — Morgan's Point is primarily Enterprise's NGL/ethane/ethylene marine export terminal; ExxonMobil's adjacent Baytown Olefins Plant is a plausible ethylene/NGL shipper here, but no source confirms a direct fuels-refinery-to-terminal link.

## Recent events
- 2026-01 — ExxonMobil broke ground on the Baytown Refinery Reconfiguration Project, adding ~8,000 bpd (~400,000 mtpa) of Group III base oil capacity by upgrading three existing units to up-cycle lower-value streams.
- 2025-06 — Fire in a polypropylene-material tower forced shutdown of the 2.6-billion-lb/yr BOP ethylene unit at the Baytown chemical complex; the adjacent 557,000 bpd Baytown Refinery itself kept operating.
- 2024-03-17 — Fired-heater tube rupture caused a hydrogen and naphtha release at the Baytown complex; CSB investigation found probable cause was creep damage plus short-term overheating (tube temperatures had exceeded the 1,200F operating limit days earlier).
