Spectrum ASA: Spectrum Commences the Ceara Basin 2

Spectrum is pleased to announce the commencement of a 6,000 km Multi-Client 2D seismic survey covering the Ceara Basin within the  Equatorial Margins of Northern Brazil, which contains sectors of  the 15 ^th licensing round.

Data is being acquired with a 12,000 m streamer with continuous recording to enable extended recording lengths and high fold data to enable full interpretation from Moho to water bottom. The data will be processed with PSTM, PSDM and Broadband products with first deliveries in Q1 2018.

Richie Miller, EVP Multi-Client Americas, comments, "We have commenced our next 2D acquisition campaign in Brazil with the BGP Challenger, starting in the prospective Ceara Basin to cover an open sector that is available in Round 15, expected to close in Q2 2018. When the survey is completed it will provide a continuous modern long-offset ten kilometer grid from the border with French Guiana to the eastern extent of the Potiguar Basin."

This survey is being carried out in partnership with BGP Marine.
