Gulf of Thailand Super Cube - Technical Challenges in the Reprocessing of 40 3D Seismic Surveys, 15,000sq.km

In early 2008, Chevron Thailand and partners contracted CGGVeritas to reprocess forty of their key 3D seismic surveys in the<br>Pattani Basin, Gulf of Thailand, with a combined area of more than 15,000 sq.km. The 40 surveys had been acquired over a<br>period of 26 years (1979 to 2005) with variable acquisition parameters, geometries and azimuths, which resulted in variable<br>amplitude and frequency content and variable fold or sampling density. The benefit of the reprocessing is enormous, but the<br>technical challenges are just as great. In this paper we present some of the technical challenges and solutions in the data<br>processing work.
