Spectrum has started a 6,000km multi-client 2D seismic survey that includes the Ceara Basin located within the offshore equatorial margins of Northern Brazil.

The area under the survey hosts sectors of the 15th licensing round.

Spectrum will carry out the whole survey in partnership with BGP Marine.

Spectrum Multi-Client Americas executive vice-president Richie Miller said: “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 10km grid from the border with French Guiana to the eastern extent of the Potiguar Basin.”

“When the survey is completed, it will provide a continuous modern long-offset 10km grid from the border with French Guiana to the eastern extent of the Potiguar Basin.”

Under the programme, the company has deployed a 12,000m streamer that will acquire and record data continuously to enable full interpretation from Moho to the water bottom.

The acquired data will be processed with PSTM, PSDM and other broadband products, with initial deliveries scheduled in the first quarter of next year.

In July, Spectrum started a new seismic survey to support the evaluation of key areas available in the Norwegian 24th licensing round.

This new Norsel High 3D acquisition included an area of minimum 1,600km comprising four blocks.

The company focuses on providing multi-client seismic surveys and high-quality seismic imaging services to the global oil and gas industry by acquiring new data, reprocessing and its interpretation.
