| Description | Hangingstone 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.
No maintenance events in the current model math for this project.
No forward-calendar entries for this project in annotations/maintenance_forward.yaml.
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.
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.
No weekly edition to date mentions this asset by name.
