Methane (CH$_4$) emissions estimates from top-down studies over oil and gas basins have revealed systematic under-estimation of CH$_4$ emissions in current national inventories. Sparse but extremely large amounts of CH$_4$ from oil and gas production activities have been detected across the globe, resulting in a significant increase of the overall O&G contribution. However, attribution to specific facilities remains a major challenge unless high-resolution images provide the sufficient granularity within O&G
