Orphan Well Due Diligence

Closure-obligation exposure is one of the central diligence questions in Alberta oil and gas M&A and surface-rights transactions. The Orphan Well Association (OWA) inventory grows when licensees become unable to fulfill closure obligations - the orphan count now runs to more than 19,000 wells in Alberta. Township Canada surfaces the orphan flag on every well plus a per-operator rollup of closure exposure.

The two diligence questions

For an M&A buyer: "What closure exposure am I inheriting?" Total Active + Suspended + Abandoned (non-orphan) wells in the seller's portfolio. Wells already on the OWA's books don't transfer closure cost - but the seller's operating history might indicate future orphan risk.

For a surface-rights holder: "Is the well on my land an OWA-funded closure or a licensee-funded one?" Different operational and timeline expectations.

Both questions are answered by the orphan flag + lifecycle status on each well.

Where to find the data

Single-well lookup

Search a well by its UWI, or click it on the Wells map layer, to open its record. The well detail shows the full lifecycle status for that well plus the orphan flag, abandonment date, and reclamation status. This is the view for diligence on a specific surface lease or a specific well being negotiated.

Operator rollup

Open the operator (licensee) view to see its whole portfolio at a glance: total wells, split by Active, Abandoned, Orphan, and Reclamation-certified. For an M&A diligence pass, this one-shot operator profile is the starting point.

Map view

In the data catalog, the Wells layer legend has an Orphan filter that surfaces only OWA-inventory wells (regardless of their lifecycle status). Combined with the standard Active/Suspended/Abandoned filters, this gives the full operator-portfolio picture.

A typical M&A workflow

1. Identify the seller's licensee. Look up the operator by name or BA code. (BA = Business Associate - every licensee has one.)
2. Open that operator's view. Total wells plus the breakdown by status.
3. Compute the inherited closure obligation roughly as: Active wells (future obligation) + Suspended wells (near-term reactivation or abandonment) + Abandoned non-orphan wells (open reclamation work).
4. Subtract the orphan count - these don't transfer in the M&A; the OWA is funding the closure.
5. Pull operator history for the highest-exposure wells. The transfer-notice history shows whether the seller has been actively divesting or accumulating.

For dollar-value diligence, the per-well closure cost estimate is industry-standard - the AER publishes liability rating models that operators use internally. Township Canada doesn't currently surface a per-well dollar estimate (that's downstream of the data we ship).

A typical surface-rights workflow

1. Open the parcel report for the title in question
2. Read the wells listing for the parcel (if the parcel sits over one or more licensed wells)
3. For each well, check the orphan flag: if orphan, OWA-funded closure; if not orphan, licensee-funded
4. For orphan wells, the timeline is OWA-driven. Their public inventory updates monthly; the well's place in the closure queue is sometimes available via OWA outreach.
5. For non-orphan abandoned wells, the licensee retains the reclamation obligation. If the licensee is suspended or in financial distress, that's an emerging orphan risk worth flagging.

What this doesn't replace

• Direct AER directives lookups - for the licence-level audit trail, the AER's regulatory portal is authoritative
• OWA direct contact - for orphan timeline expectations on a specific well
• Liability rating computation - Township Canada doesn't currently compute the per-well dollar estimate
