Fugro almost ready with 2D survey of west coast

Vol 13, PW 7 (10 Sep 09) Exploration & Production

Companies like BHP Billiton, ONGC, Essar and Adani-Welspun with NELP-VII exploration blocks in India’s western offshore will be happy to hear that Fugro will soon complete a multi-client 2D seismic study of this area.

Fugro’s study began in June and was carried out in line with a profit-share agreement signed in April with the DGH. It covers a total 6000-lkm 2D of the western offshore within the Exclusive Economic Zone, extending 200 nautical miles (370-km) from India’s coast into the Arabian Sea.

“Data is being processed at Fugro’s Mumbai centre and should be ready by the end of this month (September),â€‌ says an industry source. Fugro initially wanted the results and interpretation ready for bidders in NELP-VIII.

But that’s unlikely, as the bid closing date is October 12. PETROWATCH learns Fugro split the survey into two parts: India Deep Focus, which shot 3000-lkm using Fugro-owned vessel Geo Natuna, and India Deep Focus-2, which shot 2537-lkm using Munin Explorer, hired from SeaBird Exploration.

“This was a long offset survey using 12-km long streamers,â€‌ adds an industry source. “Fugro wants to make available an excellent data set integrating seismic, magnetic, gravity and satellite imaged seeps data.

â€‌ Eight lines have been shot, six running east to west, almost up to the limit of the Exclusive Economic Zone, with two â€کtie’ lines that run north to south. In specific terms the survey began from the Indus Fan - a set of fan-shaped sedimentary deposits in the Arabian Sea washed down by the Indus River - all the way south to the Kerala Konkan Basin.

“The results of this survey should be useful to companies interested in the Kerala Konkan Basin,â€‌ we hear. “It has so far been ignored because of the thick volcanic basalt layer (making it difficult to image).
