AER ST101: the Business Associate Snapshot
ST101 is the AER's Business Associate register. Township Canada turns it into a per-operator liability snapshot - active, abandoned, orphan, and reclamation-certified counts across a company's whole footprint.
What it is
ST101 is the Alberta Energy Regulator's Business Associate (BA) code register - the lookup that maps a BA code to a company name. Township Canada uses it to resolve the operator and licensee on every well, pipeline, and facility, and to build a per-operator liability snapshot by rolling the ST37 lifecycle counts up to each BA.
What it carries
For each operator we surface the counts that matter for diligence: active, abandoned, orphan, and reclamation-certified wells across their entire AER footprint, plus recent licence transfers. It is the difference between "this well belongs to company X" and "company X holds 40 active wells, 200 abandoned, and 15 orphans."
Coverage and refresh
We carry more than 3,000 operators in the Alberta BA register. The BA codes refresh quarterly; the liability counts rolled on top refresh monthly with ST37. Operator snapshots extend to Saskatchewan (Saskatchewan GeoAtlas) and British Columbia (BC Energy Regulator), built from each regulator's well and operator records.

How Township Canada shows it
The BA snapshot powers the operator directory and every operator drill-down in the parcel report sidebar: open an operator to see its footprint, dispositions, and wells. M&A and diligence teams use it to size liability exposure before a term sheet.
