Project description

Large methane emission events from oil and gas operations remain difficult to detect and address without systematic monitoring. Satellite-based detection alone does not explain why emissions occur or how to prevent recurrence. 

Carbon Limits conducted root cause analysis of hundreds of methane emission points identified through the OGCI Satellite Monitoring Campaign across multiple oil and gas producing countries. The work combines high-resolution GHGSat satellite detections with operator engagement, aerial imagery, on-site inspections, and operational data to confirm sources and identify underlying drivers. Analysis documented mitigation pathways ranging from equipment repair and maintenance changes to operational and process improvements. 

The work demonstrates how satellite-informed root cause insights can be integrated into methane emissions inventories to improve accuracy and support prevention of recurring events. 

This approach is relevant for oil and gas operators, national regulators, and development banks seeking to strengthen methane mitigation programmes and inventory systems in producing regions.
