![]() The leak size required to achieve a 90% probability-of-detection in this study is an order-of-magnitude larger than prior studies. Detection rates were significantly lower than prior studies focused on camera performance. ![]() ![]() Professional surveyors from 16 oil and gas companies and 8 regulatory agencies participated, completing 488 tests over a 10 month period. This study characterized the detection efficacy of OGI surveyors, using their own cameras and protocols, with controlled releases in an 8-acre outdoor facility that closely resembles upstream natural gas field operations. Optical gas imaging (OGI) is a commonly utilized leak detection method in the upstream and midstream sectors of the U.S.
