Abstract
Based on examples from the East African Rift System and Kurdistan the value of integrating multi-resolution and multi-source remote sensing data to develop a geological understanding from regional to local scale, as the exploration process progresses, is demonstrated. Geological remote sensing methods are increasingly being used in the regional assessment of frontier areas and to compliment and refine existing detailed mapping. Radar satellite imagery and medium resolution optical imagery contribute to the regional assessment and appraisal of surface geological structure and stratigraphy and the identification of natural oil seeps present on lakes and offshore areas. The launch of very high resolution satellites in recent years offering imagery at 0.5m resolution and derived DEMs at 1m grid spacing allow detailed geological mapping to be made available at the individual licence block scale, including the quantification of geological structures such as bedding dip angle and orientation. Hydrocarbon seep information from satellite based Radar data is also particularly valuable when viewed in the geological context of the surrounding area and has the potential to reduce risk in the exploration workflow.
