28th May 2014

Spectrum has commenced a 10,000 kilometre multi-client 2D seismic survey offshore Brazil in the Sergipe and Alagoas basins along the Eastern Margin of Brazil

The data is being collected by the vessel BGP Challenger and will be processed in Spectrum’s processing centre in Houston

The new acquisition program will tie key wells in the basins, including the recent Barra, Muriu, and Farfan discoveries in the Sergipe Basin. The discoveries in the deepwater area are in turbidite channel systems of Mid-Cretaceous to Early Tertiary age, with a predicted three billion barrels of oil reserve.

The data is being acquired with a 10,000 metre long offset to record the necessary information to understand the basins’ architecture as well as image the prospective zones in the mid and lower Cretaceous sections.

The data is being collected by the vessel BGP Challenger and will be processed in Spectrum’s processing centre in Houston. PreSTM and PreSDM data will be available in Q4 2014.

To supplement the new acquisition in this active exploration area, Spectrum has just completed the reprocessing of 8,130 kilometres of data through both PreSTM and PreSDM and is also offering this data to industry in order to get a head start on the expected upcoming round in 2015.

Richie Miller, EVP multi-client North and South America, comments: “Following on from our successful equatorial margins campaign for Round 11, we have commenced the Sergipe 2D programme. We have experienced good client interest due to the lack of existing modern seismic data in the deepwater and ultra-deepwaters. We are confident that the data will be highly valuable for the industry ahead of the next licensing round in the area.”
