Spectrum Commences Potiguar 2D Multi-Client Survey in Brazil

The acquisition of the Phase II of the 2D campaign over the Foz do Amazonas basin in Brazil was completed this week, totalling 6,729 line kilometers. Now Spectrum moves east to the Potigar Basin for another extension of the Equatorial Margin coverage ahead of Brazil's upcoming 11(th) license round.

The seismic vessel will mobilize for the program and start up by end November for a 4,000 km survey on a 10x10km grid in 500-4000m water depth. The Potigar survey is supported by industry funding and will be completed in the fourth quarter 2012, following which Spectrum will have collected approximately 45,000 km of new long offset data over this highly prospective equatorial margin.

Richie Miller, EVP Multi-Client North & South America, comments: "Due to the high efficiency of the acquisition achieved on the previous surveys in these waters, we have time and are in a position to respond to industry interest for the Potigar basin and acquire the final area that is expected to be included for round 11. The Potigar survey is a natural extension from the Northern Margins survey that was acquired earlier in 2012. With this survey, Spectrum will have full coverage over all offshore sector blocks that are expected to be included in license round 11."

The seismic data is being acquired by the Seabird vessel Hawk Explorer and the data will be processed at Spectrum's processing center in Houston, with the final products scheduled for delivery in April 2013.
