Mobile Sensor Optimal Path Planning for Monitoring Methane Emissions in an Oil Field
This project addresses the problem of detecting methane emissions from distributed natural gas and oil field production sites using a mobile sampling vehicle that can measure methane concentrations along public roadways over a desired region of interest (ROI). Assuming the oil field, the wells locations and the roadmap is known, the algorithm finds an optimal path for the tradeoff between the value of measurement and cost.

Methane, CH4, is a greenhouse gas twenty times more effective than carbon dioxide in trapping heat in the atmosphere over a 100 year period. Approximately 35% of the methane released by these systems occurs during the field exploration and production stages of the natural gas and oil extraction processes.
The optimal monitoring of oil fields by a mobile sensor is the motivation for this project.
