The TGS Gigante project is comprised of 188,497 km of 2D seismic data acquired in 2016 and primarily covering the offshore Mexican side of the Gulf of Mexico (Figure 1). Within the survey, 180 seismic lines with 5 km average spacing are in the increasingly important Yucatan area, where active hydrocarbon exploration is taking place. The data was acquired with a 12 km streamer length and a 2 ms sample interval. Both Kirchhoff and Reverse Time Migration significantly improve the seismic image quality in the structurally complex offshore Yucatan area.
