AI-POWERED Breakthrough in Coverage, GRANULARITY AND COST
MethaneScan® AI is a tiered multi-satellite monitoring system that tracks daily-to-weekly methane emission performance at oil and gas and other methane-emitting assets across the globe. It is designed to greatly reduce attribution uncertainty while retaining high spatial/temporal coverage and ensuring the computational efficiency required for global scaling.
The service platform processes a vast set of open data from a variety of medium- to high-resolution satellite sensors to detect methane plumes worldwide and attribute such emissions to asset owners for managing risk, validating data and benchmarking. Its unique compute-efficient deep learning model technology can be used to validate emissions claims at the asset, basin or company level at very low cost.
“MethaneScan® AI is well suited for systematic site-level leak detection since every site is scanned every week. This contrasts with free satellite monitoring by third parties which target super-emitters and do not revisit any given site on a regular interval. ”
Technical Specifications
Spatial Resolution: 30 m
Revisit Interval: Weekly scans
Geographic Coverage: Anywhere onshore given suitable cloud coverage at the target sites during satellite flyovers. See Coverage Areas.
Detection Threshold: 200 kg/hr or better. Fills coverage gaps where highly sensitive onsite sensors or cameras have yet to be deployed or site visits are impractical.
History: 2015 to near real time
Detected plumes and related data are analyzed by GEO’s scientists and rated as to the likelihood they are real. Rating system is similar to that used by radiologists in assessing whether or not tumors observed on medical imaging are real.
COVERAGE AREAS
MethaneScan® AI coverage areas – where a combination of high satellite coverage and low average cloud cover lead to Medium to Very High suitability – are highlighted in green in the map below. High latitudes and equatorial regions are typically low suitability due to cloud cover and other viewing challenges (e.g. extreme solar zenith angles).
