Abstract The distribution of natural marine hydrocarbon seepage has great significance for the early stage offshore petroleum
exploration. In this paper, a satellite synchronous observation experiment was made.
oil slick was made with machine oil and imaged by RadarSAT-2 SAR data after 14 minutes. Some conclusions have been reached: under
a certain suitable sea condition, it is possible for SAR data with resolution of 3 meters to detect oil slick with the thickness
of several micron meters, and there is 5 dB relative damping on sea surface wave in this case; SAR measurements can further
confirm the influence of wind and current condition on the evolution of oil slick.
