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, suspended, abandoned, and orphan 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, suspended, 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 suspended, and 15 orphans."
Coverage and refresh
We carry more than 3,000 operators in the BA register. The BA codes refresh quarterly; the liability counts rolled on top refresh monthly with ST37.

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.
