New 2D multi-client project in Sergipe Basin offshore Brazil

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

The new acquisition programme 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, 3 billion bbls of oil in place and rising, are in turbidite channel systems of Mid-Cretaceous to Early Tertiary age.

The data is being acquired with a 10 000 m 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 center 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 8130 km 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 & 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 ultradeepwaters. We are confident that the data will be highly valuable for the industry ahead of the next licensing round in the area.”

The survey is supported by industry funding.
