have both indicated that the equatorial margin will be the next great challenge for Brazil’s oil and gas industry after the pre-salt, mainly due to the fact that there have been signifi cant analogous oil and gas discoveries in West Africa, and there is much geological similarity between the equatorial margins on both sides of the Atlantic. The seismic data, including the re-processed data indicates that ro- bust reservoirs are present in all the ba- sins along the EM. Recently, there has been exploratory success by Petrobras at an unnamed deepwater play around 200km offshore of the coast of the state of Pará, in the Pará-Maranhão Basin and also off Rio Grande do Norte, in the Po- tiguar Basin, where the Pitú exploration well, 1,731 meters deep and 55km from the coast, struck oil. Spectrum Seismic Survey Campaign In 2013 Spectrum ASA acquired 38,588km of new long offset 2D seismic data covering the Foz do Amazonas, Barreirinhas, Ceará and Potiguar Basins in the EM. In addition, a re-processing effort is underway on a seismic dataset tying the Foz do Amazonas, Pará-Mara- nhão and Barreirinhas Basins. This re- processing effort is indicating that some of these basins may be linked. Spectrum has accumulated more than 48,000km of Multi-Client seismic in this area of extremely high potential. This data, along with fi nal PSTM (Pre-Stack Time Migration), PSDM (Pre-Stack Depth Migration) was made available for Bra- zil’s 11th round of bidding. In December 2013, Spectrum and CGG announced that it would launch, as equal partners, a large, high-end BroadSeis 3D multi-client survey pro- gram offshore Brazil focusing on a large area of the Foz do Amazonas Ba- sin. Rune Eng, CEO of Spectrum said, “This opportunity for us to join forces with CGG in our project development and employ CGG’s top-notch technol- ogy in our next phase in this area is a milestone for Spectrum.” Rune also highlighted that “the Northern Mar- www.seadiscovery.com Marine Technology Reporter 35 MTR #3 (34-49).indd 35 4/9/2014 10:52:01 AM
