OSLO, Norway --The Uruguayan Ministry of Energy and Environment has contracted Wavefield Inseis to conduct a multi-client long-offset 2D survey covering 7,000 km (4,350 mi).

Wavefield plans to use the M/VBergen Surveyor with an 8,000 m (5 mi) streamer starting in June. Marine gravity and magnetic data will be recorded also. The result of final processing is scheduled to be available by year-end.

Uruguay's state company Ancap is a partner and will share any revenues from sales of the information to oil companies.

"The Uruguay sedimentary basins are composed of rocks of Paleozoic to Mesozoic ages and were deposited in the pre-rift, sin-rift, sag, and passive margin stages," says Jan B. Gateman, senior VP G&G of Wavefield. "Existing wells drilled on structural highs in the Punta del Este basin, proved that these sediments are within the hydrocarbon generation window.

"In both, the Punta del Este and Pelotas basins, several leads of structural and stratigraphic character have been identified on older seismic data. These hydrocarbon leads are located in a wide range of water depths".

The survey data will be promoted together with a comprehensive interpretation study that will tie and calibrate the geology of the offshore basins of Uruguay with the neighboring basins located in Brazil and Argentina.
