EO4OG (Earth observation for oil and gas) provides a comprehensive guide to geospatial products using EO data dedicated to meeting the needs and challenges of the oil & gas industry. The project first of all identified a total of 224 challenges faced by the O&G industry where there is a potential for satellite EO data to play a role in providing a solution. This led to the definition of 94 products. Finally, 19 cases or examples showing where some of these products have been successfully applied with the O&G industry. All the information coming from this extensive analysis can be found at the project’s website.
