P02 IMPROVED STATIC CORRECTIONS FOR VIBROSEIS LINE NC151-V532 OVER SAND DUNES IN WESTERN LIBYA Summary This paper deals with static corrections on seismic reflection profile over sand dunes in concession NC151 in western Libya. Two methods of computing field statics have been implemented and the results are compared after processing in Durham using ProMAX software. The refraction method in which field statics are estimated as half the plus time at each station and then adjusted to uphole data with linear interpolation yielded a significant improvement over the conventional method previously used which relies solely on interpolation of the near-surface velocity
