ONGC extends TZ seismic bid deadline

Two years on, ONGC seems no closer to shooting 3D over a 'Transition Zone' west of the producing Gandhar field in the Cambay basin.

ONGC has indefinitely extended the bid deadline to shoot 200-sq km 3D in a region 60% onland and 40% shallow offshore. Earlier it moved the deadline from July 24 to July 30.

"ONGC failed to hire a contractor twice before," says a source. "This is the third tender." Among likely bidders are Russia's Geotech, US-based Geokinetics and Kazakhstan's Geo Energi - all specialise in Transition Zone seismic.

ONGC first issued this tender in 2015, receiving bids from Geotech and Geokinetics. "Geotech was disqualified on technical grounds," we hear.

In 2016 ONGC received bids from the same two. "Geotech was disqualified leaving Geokinetics alone," we hear.

Another source adds ONGC's Rs128cr ($21m) budget is low and $35m is more feasible. "Working in a Transition Zone is difficult," he adds.

"The onland part has salt pans making drilling shot holes hard." Offshore, the selected contractor must mobilise a boat with an air gun, and support vessels.
