During five years, in the frame of the NAOMI (New Advanced Observation Method Integration) research project, Total and ONERA have worked on radar and optical imagery to detect, characterize and quantify slicks at sea. Laboratory and pool measurements, physical modelling and offshore experiments have been combined to fully understand the signal coll...
Large-scale mapping of coastal oil spills and their monitoring over time is a major issue that can be adressed by using hyperspectral images and dedicated processing. Previous researches have shown that it is possible to map the polluted coastline caused by the explosion of the Deepwater Horizon (DwH) platform from AVIRIS images (AVIRIS: Airborne V...
Forest observation with RADAR waves is particularly relevant due to their properties of penetration under canopy. As an example, European Space Agency (ESA) will launch synthetic aperture radar (SAR) operating at P-Band in order to determine the distribution of above-ground biomass in forests. The techniques foreseen include study of radiometry, po...
Detecting onshore hydrocarbon is a major topic for both environmental monitoring and exploration. In this work, a hyperspectral image acquired nearby an old oil extraction site is analyzed. The area of interest includes a pit filled with bio-degraded heavy oil, surrounded by herbaceous vegetation and many lagoons. First, we focused on methodologies...
The remote assessment of soil contamination remains difficult in vegetated areas. Recent advances in hyperspectral spectroscopy suggest making use of plant reflectance to monitor oil and gas leakage from industrial facilities. However, knowledge about plant response to oil contamination is still limited, so only very few imaging applications are po...
Cette étude analyse les mécanismes de détournement de la rente pétrolière et gazière à tous les niveaux de la production et de la commercialisation d'hydrocarbures, depuis la tête de puits, avec le percement des pipelines (bunkering), jusqu'à l'exportation de brut et l'importation d'essence raffinée, sans oublier l'évasion de capitaux dans des para...
