We applied full waveform inversion (FWI) to an offshore gas field in Trinidad with complex geology. We obtained a detailed velocity model up to 30 Hz using Ocean Bottom Cable (OBC) data, a first in this basin. The corresponding FWI-derived reflectivity (FDR) image provides geologic information consistent with the drilled wells: it serves as a high-resolution seismic image for interpretation and a useful reference for well planning and drilling decisions.
