Spectrum starts Brazil shoot

Under way: seismic trawl off Brazil

Norwegian seismic contractor Spectrum has kicked off a multi-client 2D survey in the deep-water Sergipe-Alagoas basin off Brazil.

The emerging Eastern Margin area off Brazil's north-western coast has attracted industry attention following the Petrobras discoveries of Barra, Muriu and Farfan.

The goal will be to supply data to industry before potential bidding activity in the region in 2015.

Spectrum said the survey had attracted strong industry interest due to the lack of existing modern seismic data in deep-water and ultra-deepwater areas, with funding being sourced from "a number" of company clients.

Petrobras has recently ramped up activity in the area, with the state-led oil giant planning to spend $5.7 billion on exploration and production activities in the basin by 2017.

Deep-water areas are estimated to contain 3 billion barrels of oil in place in turbidite channel systems of mid-Cretaceous to early Tertiary age.

The quality and type of finds has led to comparison to Brazil's prolific Campos basin.

The BGP Challenger vessel will carry out the work, with processing carried out in Houston.

Spectrum has also wrapped up work reprocessing 8130 kilometres of data through the PreSTM and PreSDM systems which should be available in the fourth quarter.
