DescriptionHangingstone is a steam-assisted gravity drainage (SAGD) oil sands project in the southern Athabasca region, about 20 km southwest of Fort McMurray. Athabasca Oil Corporation's Hangingstone 1 project was sanctioned in 2012 with Phase 1 capacity of 12,000 bbl/d. It is separate from the JACOS/Greenfire Hangingstone Expansion, which is tracked separately under gfr_hangingstone_exp.

How to read Hangingstone (Athabasca): Seasonal baseline off a 9.0 kb/d trailing-12m baseline. No 2027 turnaround statements; single-month dips are seasonal factors repeating the last 3 years.

Maintenance

No maintenance events in the current model math for this project.

No forward-calendar entries for this project in annotations/maintenance_forward.yaml.

Outlook

Named assumptions: Seasonal baseline off a 9.0 kb/d trailing-12m baseline. No 2027 turnaround statements; single-month dips are seasonal factors repeating the last 3 years.

Confirmation status: model forecast; maintenance impacts enter the math only from public-confirmed guidance.

Market relevance

In-situ bitumen has flexible disposition (dilbit to market or upgrader feed). In the model, Hangingstone output is unchanged by upgrader outages and any upgrader-bound share is assumed diverted to dilbit, so its 11.3 kb/d 12-month forecast average is a steady contributor to marketable dilbit across the tradable window.

Basis: model-derived from the dashboard series above; no external view is added.
