Verisk AER Scientists Timothy G Pernini and T Scott Zaccheo co-authored a paper recently submitted for publication which highlights the GreenLITE™ system, co-developed by AER.
The GreenLITE™ emission monitoring system detected, located, and quantified methane emissions from a series of single-blind controlled releases with no prior knowledge of timing, locations, or release rates. System performance was evaluated against metrics defined in the Continuous Monitoring Protocol established by the Methane Emissions Technology Evaluation Center (METEC) at Colorado State University. This protocol allows more direct comparison of system performance between disparate measurement technologies. The results presented demonstrate GreenLITE™’s ability to locate and quantify gas leaks in general, but particularly methane leaks associated with upstream oil and gas operations.
Figure 1. Layout of GreenLITE™ system at the test site. T01 and T02 are the two laser transceiver locations along the southern edge, yellow markers are the reflector locations, green lines are the chords measured by T01, and blue lines are the chords measured by T02. The red boxes are used as bounding boxes for computing emissions and providing an estimated location of the emission. Blind controlled release locations are marked with red and black bullseye symbols.
