Detection and Characterization of Natural Oil Seeps and Oil Slicks in the Shallow, Deep and Ultra Deep Waters of Sergipe-Alagoas Basins, using Radar SAT-1 Satellite data
Multiclient studies available for the upcoming Bidding Rounds
Satellite Radarsat-1 fine detection and use to characterize areas of oil seeps is considered today a strategic technology for exploration in frontier basins were geophysical and geological data are scarce or non-existent for all major petroleum E&P companies.
The application of oil slick satellite survey, in the offshore realm of the Basin, reduces considerably the exploration risk for oil exploration in deep and ultra-deep water areas where little exploration wells have been drilled up to now. Such type of survey is low cost, fast and very effective in covering large areas. Also, it provides relevant information for planning the acquisition of seafloor piston cores and electromagnetic survey (EMGS). The presence of seepage slicks in the Sergipe-Alagoas Basin, detected through RADARSAT-1 satellite image analysis, indicates the existence of present oil generation and migration processes associated to active oil systems. The detection of 27 seepage slicks identified from very shallow water to ultra-deep water regions, with surface areas varying between 0.02 and 3.80 km², suggests that an overcharged generative hydrocarbon source rocks petroleum system occur widespread around the whole Basin.
