This project will demonstrate if work truck- mounted sensor technologies are reliable, scalable and could be effectively deployed for methane detection and measurement from major sources such as cold light/medium and heavy oil production and natural gas production in the Canadian unconventional oil and gas (UOG) sector. These sensors could provide a low cost, efficient solution to manage field-wide ambient air monitoring that reduces methane emissions from unplanned emissions and removes the need for interval-based leak inspections. The overall project impact would meaningfully contribute to the federal government’s goal to reduce methane emissions by allowing screening and triage of emission sources so that operators and regulators can focus on super emitters in order to create early emissions reduction gains. It would also enable cost reductions of mitigation measures through potential deployment of sensors once developed among several operators.
