A REVIEW OF CLOSE-RANGE AND SCREENING TECHNOLOGIES FOR MITIGATING FUGITIVE METHANE EMISSIONS IN UPSTREAM OIL AND GAS
Fugitive methane emissions from the oil and gas industry are targeted using leak detection and repair (LDAR) programs. Until recently, only a limited number of measurement standards have been permitted by most regulators, with emphasis on close-range methods (e.g. Method-21, optical gas imaging). Although close-range methods are essential for source identification, they can be labor-intensive. June 26, 2019.
