Currently, methane sensors record concentration with time and location, not mass of methane released. The heart of the Arolytics innovation is techniques to simulate plumes of methane leaking from equipment in order to reconcile the data from various types of sensors (continuous on site, aerial surveys , imaging etc.) with the mass of methane released from a given site or piece of equipment. Enhancement of management of methane monitoring will be via advanced analytics to detect patterns and guide placement of equipment and surveys in the field. This project will develop two software packages to help oil and gas operators to A) Record, reconcile, and report methane emissions data from various sources including bottom up reports and monitors in the field (AroFEMP), and B) Plan and optimize programs to monitor, detect and repair methane leaks as efficiently as possible (AroViz).
