On 23rd July, the GGS-Atlantic commenced the acquisition of Spectrum's Big Wave Phase 2 multi client seismic survey in the eastern Gulf of Mexico.  Phase 2 of Spectrum's Big Wave multi client programme is a total of 14,000km long offset, high quality seismic data and includes a 2,000km well tie survey to the east of the main study area. This new survey compliments the previously acquired data sets and will expand Spectrum's coverage in the eastern Gulf of Mexico to over 52,000km.

Spectrum's seismic vessel, GGS-Atlantic, will be fully utilised acquiring Phase 2 until December 2009.  The data processing will be undertaken at Spectrum's state of the art computer centre in Houston with a sequence including both pre stack time and pre stack depth migration.

An additional pre-funder has been secured for Phase 2, making it 5 major oil companies to date that have signed up ensuring it is close to being fully prefunded.
