# San Antonio Refinery

San Antonio Refinery, San Antonio, TX. 20,000 bpd crude capacity (EIA-820). Injects into NuStar Pipeline; reaches 1 delivery points and 6 terminals by published tariff. Crude supply, outlets, events.

- Location: San Antonio, TX
- Status: active
- Crude capacity: 20,000 bpd (EIA-820)
- Operator: The San Antonio Refinery LLC
- Parent: Traced through several owners: originally NuStar Refining, LLC / NuStar Logistics, L.P. (a NuStar Energy subsidiary) -> sold to Calumet Specialty Products Partners, L.P. for ~$115M in a deal signed Dec 2012 and closed Jan 2013 -> Calumet sold the refinery and related crude terminal/pipeline assets to 'Starlight Relativity Acquisition Company' for $63M, effective Nov 1, 2019. No source found this session that directly documents 'The San Antonio Refinery LLC' as Starlight's renamed operating entity, but the entity name and Calumet's 2019 divestiture are strongly consistent with it being the post-2019 owner/operator name; treat this linkage as a well-supported inference rather than a directly confirmed fact.

## Pipelines it injects into
- NuStar Pipeline at San Antonio, Kirby Terminal (same city) — https://thinkingonenergy.com/supply/pipeline/nustar-pipeline/

## Reach by published tariff route
| Pipeline | Delivery points | Terminals | Lowest ¢/bbl | Median ¢/bbl |
|---|---|---|---|---|
| NuStar Pipeline | 1 | 6 | 113.82 | 113.82 |

## Crude supply
- pipeline: Karnes North Pipeline System (KNPS), operated (as of the Calumet era) by TexStar Midstream Logistics, L.P. — Per Calumet's own 10-K-era disclosures, the refinery received at least 12,000 bpd of light Eagle Ford crude via KNPS into its Elmendorf terminal (~188,000-200,000 bbl storage), then onward to the refinery. This is a TexStar Midstream system, not a NuStar-branded pipeline, despite NuStar's earlier (pre-2013) ownership of the refinery itself.

## Product outlets
- rail: railcar service — Calumet's 10-K-era disclosures state the refinery 'ships products by railcar and truck service' with sales via spot agreements and short-term contracts — there is no named outbound products pipeline documented for this refinery.
- truck_rack: truck rack at the refinery — Same source as above.

## Recent events
- 2019-11-01 — Calumet Specialty Products Partners closed the sale of its San Antonio refinery and related crude terminal/pipeline assets to 'Starlight Relativity Acquisition Company' for $63M, in a deal that also settled outstanding litigation with TexStar Midstream Logistics.
