Is well classification determined solely by gas-oil ratio (GOR)?

Can a gas well produce oil and still remain classified as a gas well?

Can historical well classifications be evaluated using today's rules?

Will reclassifying a gas well as an oil well make flaring approvable?

Common Question

What is one of the most common misconceptions about well classification?

Archive Findings

One of the most consistent themes identified throughout the archive is the assumption that well classification can be determined using a single engineering parameter. Archived correspondence repeatedly demonstrates that regulators evaluated multiple technical considerations when reviewing classification questions. Production behaviour, historical performance, fluid characteristics and regulatory requirements all contributed to the overall assessment. The archive consistently supports the conclusion that well classification has historically required professional engineering judgment supported by regulatory guidance.

Engineering Insight

Engineers should resist the temptation to simplify complex classification decisions into a single calculation. Historical records consistently demonstrate that robust technical evaluations consider multiple sources of information before reaching a conclusion. The practical lesson is simple: classification should be treated as a technical interpretation supported by evidence, not as a checkbox exercise.

Current Guidance

Current well classification guidance is provided in AER Manual 014. Historical context can assist with legacy interpretation, but current AER guidance should always be reviewed before making compliance decisions.

Well Fluid Classification, Licensee Obligations and IWCP Updates

This April 2016 newsletter discusses the AER release of Manual 014 for liquid classification and well status fluid type determination for oil and gas wells. It also announces Benoit Regulatory’s strategic alliance with Acipenser Resources, summarizes AER Bulletin 2016-10 regarding licensee obligations in insolvency situations, and covers AER planning updates, OGC isotope gas analyses, groundwater protection elevations, IWCP program reminders, and reclamation reporting changes.
