Leak Detection and Repair (LDAR) Inspections
An infrared camera sees what the naked eye cannot. Using a Forward Looking Infrared (FLIR) GF320 optical gas imaging camera, VOC emission leaks can be identified from components regulated at the state and federal level. Our LDAR inspections are documented and managed with Connect, an operational compliance database created by CGRS with regulatory reporting in mind.
Audio/Visual/Olfactory (AVO) Inspections
An AVO inspection seeks to identify and document operational and non-operational equipment on-site in order to notify clients of non-compliance occurrences. CGRS performs audio, visual, olfactory (AVO) inspections to meet various regulatory requirements.
E&P Site-Specific Sampling (Oil, Natural Gas, Production Water)
Site-specific emission factors are generated from a field sample, allowing for the most accurate emission factor for air permitting of various sources. Bubble point technology and strict adherence to sampling protocols ensures a high level of sampling integrity.
