Abstract

Summary

This paper illustrates application of visco-acoustic full-waveform inversion (Q-FWI) and common image point (CIP) tomography techniques to develop a more accurate earth model for a shallow-water, shallow-gas dataset from Gulf of Thailand, despite the limited bandwidth and short-offset attributes of the dataset available. The subsequent Q-imaging successfully reduced geological uncertainties through the compensation of absorption effects, improved fault definition and structural information for the key subsurface targets.
