'CGG bias at ONGC!' say seismic contractors

Seismic contractors are outraged by ONGC's likely qualification criteria in a forthcoming broadband 3D tender, which they allege is an attempt to favour technology developed by CGGVeritas.

By the end of this month (April) ONGC is expected to issue a tender to shoot and process 3500-sq km broadband 3D mainly in the western offshore. On April 1, ONGC received EoIs from CGGVeritas, PGS, Polarcus, WesternGeco, Sovcomflot, and Turkey's TPAO.

But contractors can't understand why ONGC wants eligible bidders to have completed at least one broadband acquisition in the past five years using the 'Broadband Source' method. Just one company, CGG, has proprietary technology called - coincidentally - BroadSource.

"ONGC could have simply said it is open to all acquisition methods if its idea was not to favour one method," says a contractor. "BroadSource is just one technology in the market.

Let's see what the tender says." If as they fear the tender focuses on one acquisition method contractors promise vigorous protests. "We won't let this go unchallenged," says a source.

ONGC wants to shoot 3D across 1186-sq km at the western offshore B-157 field; 1780-sq km across south and southwest Mumbai High; 2765-sq km across the west of Bassein and Neelam fields; 1250-sq km over offshore Gujarat field GK-28; and 370-sq km over GS-29 in the eastern offshore.
