What you need to know about Methane,Flaring and Venting

Impact to the Environment

2 min read

Flaring not only serves as a method for disposal but also has implications for air quality and climate change. For instance, the burning process converts methane into carbon dioxide, a less potent greenhouse gas, but still contributes to overall greenhouse gas emissions.

The methane released during venting can significantly impact the environment. Methane is a potent greenhouse gas that traps heat in the atmosphere more effectively than carbon dioxide, making its release a critical concern in efforts to mitigate climate change. For example, the environmental impact of venting can be illustrated by comparing methane’s global warming potential (GWP) to that of carbon dioxide over a 20-year period, where methane’s GWP is approximately 84-87 times greater.

Why Track These Emissions?

Tracking emissions related to flaring and venting is essential for understanding their environmental impact. Companies must adhere to regulations that require monitoring and reporting of both flared and vented volumes. This data is crucial for making informed decisions about emissions reduction strategies and for demonstrating compliance with environmental standards.

Moreover, operators often conduct audits and assessments to ensure that they are complying with regulatory requirements. This process includes evaluating equipment efficiency and exploring new technologies that can minimize flaring and venting events. By implementing advanced monitoring systems, operators can better manage gas emissions and reduce their environmental footprint.

In terms of ESG reporting, the measurement of emissions from flaring and venting is increasingly becoming part of corporate sustainability strategies. Investors are seeking transparency regarding environmental impacts, and companies that can demonstrate effective emissions management are likely to attract more support.

Operators track volumes at each facility or well site. They compare measured volumes to regulatory thresholds under AER Directive 060. And they track exceedances and aggregate data for ESG and compliance reporting.

For example, integrating real-time monitoring systems like the capabilities provided by Nai Portal allows operators to react quickly to any unusual emissions patterns, thereby reducing the potential for excess flaring or venting. Operators are also exploring carbon capture technologies to mitigate emissions associated with flaring and venting. Furthermore, the incorporation of renewable energy sources into operations can significantly reduce the need for flaring by providing alternative energy options

Use in ESG reporting

Understanding the regulatory landscape is crucial for operators. The AER not only sets limits but also works to educate operators about best practices to minimize flaring and venting. This educational aspect is vital for fostering a culture of responsibility among operators.

Examples of best practices include implementing vapor recovery systems at sites where flaring is common. These systems can capture gases that would otherwise be flared and redirect them for sale or use, reducing waste and emissions.

1. Operators measure flared and vented gas at facility level using gas meters and sensors.
2. Operators in Alberta submit data to the Alberta Energy Regulator (AER) via Petrinex.
3. AER compiles datasets like ST60B that report gas flared, gas vented, emissions by facility, and operator level metrics
4. Operators aggregate data monthly, quarterly, or annually, benchmark performance against peers and Directive 060 limits, and convert volumes into ESG metrics such as emissions intensity, GHG equivalent emissions, or flaring ratios.

Regulatory Limits Under Directive 060

AER sets regulatory thresholds—under Directive 060, which applies across upstream petroleum operations—for flaring, incinerating, and venting activities
These thresholds vary depending on:

• Type of operation (well test, battery, facility, pipeline)
• Duration (continuous vs temporary flaring)
• Gas composition (e.g., sour gas faces stricter limits)
• Facility type and scale

Key Threshold Examples

Operators are also encouraged to participate in voluntary initiatives aimed at reducing methane emissions, which can help improve their public image while contributing positively to environmental sustainability.

• Well testing: Operators cannot flare or vent more than a cumulative volume (commonly capped at 900 m³/day over specified durations), unless they obtain AER approval
• Routine flaring at batteries or facilities: If flaring averages greater than approximately 500 m³/day, operators must justify volumes economically or pursue conservation alternatives
• Methane venting: AER strongly discourages routine methane venting unless no alternative exists AER sets vent gas limits that are typically lower than flaring thresholds due to methane’s higher greenhouse impact

Operator Compliance and Enforcement

Operators report volumes monthly through Petrinex, following measurement and reporting mandates in Directive 017 and 060. When volumes exceed thresholds, operators must submit permit requests, justify exceedances, and propose corrective actions. If operators repeatedly violate limits or fail to justify exceedances, AER may impose enforcement actions, fines, or suspend operations.

Ultimately, the commitment to reducing flaring and venting not only aligns with regulatory requirements but also resonates with a growing number of stakeholders who prioritize sustainability and environmental stewardship. By taking proactive measures, operators can ensure a more sustainable future while also enhancing their operational efficiency.
