Glossary of Terms

The provincial regulator responsible for the responsible, efficient, orderly, and safe development of energy resources in Alberta. The AER enforces compliance with Directive 060.

A manual inspection method where an inspector walks the facility and uses their senses — hearing, sight, and smell — to detect signs of a fugitive gas emission. Required at minimum annually under AER Directive 060.

An individual piece of equipment at a facility that must be inspected under LDAR requirements. Examples include valves, connectors, flanges, pump seals, open-ended lines, and pressure relief valves.

A unique identifier assigned to each inspectable component (e.g. V-101, FLG-04). Used to link inspection results, leak records, and repair records in reports.

AER Directive 060 — the Alberta Energy Regulator's regulatory requirement for upstream oil and gas facilities to conduct annual LDAR programs. It specifies inspection methods, leak documentation requirements, the 30-day repair window, and annual reporting obligations.

An inspection saved with DRAFT status. Draft inspections are stored but do not create leak records and are excluded from compliance PDF reports. Must be completed before they are counted toward D060 compliance.

A licensed production site — such as a battery, wellsite, or compressor station. Each facility has its own component registry, inspection history, and AER licence number in Fieldnorm.

A component classified as a significant emission source under D060, typically a pneumatic device. High-bleed components are flagged with a ⚡ icon in Fieldnorm inspection forms to draw inspector attention.

A leak status indicating that repair work has started but is not yet complete. If a leak is still IN_REPAIR past the 30-day D060 deadline, it is considered overdue.

A formal survey of all active components at a facility, recording whether each component passes, fails, or has a detected leak. Completed inspections create leak records for any LEAK-result components and are included in compliance reports.

A regulatory program requiring oil and gas operators to systematically inspect equipment for fugitive gas emissions, document detected leaks, repair them within a specified timeframe, and report compliance to the regulator.

A record automatically created in Fieldnorm when a component is marked LEAK in a completed inspection. Contains the detection date, 30-day repair deadline, current status, repair date, and repair notes.

An inspection method using a specialised thermal infrared camera to visualise hydrocarbon gas emissions that are invisible to the naked eye. OGI is an AER-approved inspection method and is required for certain higher-risk facilities under D060.

The AER's online portal for submitting regulatory reports and applications. Operators export their annual D060 compliance PDF from Fieldnorm and upload it through OneStop.

A leak status indicating the leak has been detected but no repair work has begun. Leaks remain OPEN until updated to IN_REPAIR, REPAIRED, or VERIFIED.

A leak whose 30-day D060 repair deadline has passed and whose status is still OPEN or IN_REPAIR. Overdue leaks are flagged in red on the Dashboard, the Leaks & Repairs page, and in the PDF compliance report.

A web application that can be installed to a device's home screen and functions similarly to a native app. Fieldnorm is built as a PWA for use on mobile devices in the field.

The date by which a detected leak must be repaired under AER Directive 060. Calculated as the detection date plus 30 calendar days. Fieldnorm calculates and displays this deadline automatically for every leak record.

A leak status indicating the physical repair has been completed. A Repair Date must be entered. The leak is considered compliant if the Repair Date is within 30 days of the detection date.

A leak status indicating the repair has been completed and a post-repair inspection has confirmed the leak is resolved. Requires both a Repair Date and a Verification Date.
