This survey is particularly designed to handle the challenges related to deeper, higher-risk Jurassic and Triassic performs, usually underneath high-pressure, high-temperature circumstances, and the presence of complicated structural processes related to Permian salt motion. The mixture of full-azimuth imaging, further fold and near-offset knowledge will lead to important enchancment of deep illumination and noise elimination, whereas serving to to light up and picture the steep flanks and complicated structure created by salt diapirism.
