Quantifying remote, inaccessible emission sources (primarily cold vents) has been one of the biggest challenges for bottom-up tracking. These types of sources are usually the major methane emission sources and must be quantified accurately to fully characterize site-level emissions. Opgal’s Long Range Quantitative Optical Gas Imaging (QOGI) software and validation platform address these hurdles directly, providing a comprehensive solution that fulfills strict international regulatory requirements and framework standards.

Opgal’s QOGI is validated as the Best Available Technology (BAT) for Level 4 source level/bottom-up reporting of remote, major emission sources. The real-world feasibility of this technology is backed by empirical data from. a landmark European Gas Research Group (GERG) blind controlled-release study titled, “Assessment of current methane emissions quantification techniques for natural gas midstream applications.” Opgal’s QOGI significantly outclassed alternative source-level quantification technologies featured in the study, especially on remote (long-range) vents.
