Leak Detection and Repair (LDAR) Surveys

Leak Detection and Repair (LDAR) surveys are comprehensive inspections and monitoring programs conducted in various industries, including the oil and gas sector, petrochemical industry, and manufacturing facilities. The primary objective of LDAR surveys is to identify and address fugitive emissions.

Identification: Our trained technicians use our specialized AURA OGI cameras to detect emissions. These emissions are often invisible to the naked eye.

Quantification: Once a leak is detected, the LDAR survey measures the concentration and volume of the emissions. This information helps in assessing the severity of the leak.

Classification: Leaks are categorized based on their size and severity, with different classifications requiring various levels of response and repair.

Documentation: Detailed records are kept for each identified leak, including its location, size, classification, and any necessary repairs or maintenance actions. Our AURA OGI onboard sensor and location metadata is encoded directly into the OGI image files, simplifying documentation, compliance and auditability.

Reporting: Regulatory agencies often require companies to report their LDAR survey findings, demonstrating compliance with emissions regulations.

Repair: Leaks are repaired promptly to prevent further emissions. Depending on the severity, repairs can range from simple adjustments to complete equipment replacements.

Follow-up survey: After repairs, follow-up surveys may be conducted to ensure that the emissions issue has been effectively resolved.

Compliance:Companies conducting LDAR surveys aim to maintain compliance with environmental regulations, reduce emissions, and minimize the environmental impact of their operations.


Overall, LDAR surveys are a critical component of emissions monitoring and environmental protection efforts, helping industries reduce their impact on air quality and contribute to sustainability goals.
