Finding more Gavea’s in the Campos Basin and beyond the Salt Domes
November 8, 2016

Spectrum’s Neil Hodgson and Karyna Rodriguez discuss how a new acquisition programme in the Campos Basin will help define the plays of the future. First published in Geo ExPro, October 2016.

The recently discovered Seat, Gavea and Pão de Açúcar fields all lie within a Campos Basin block estimated to contain resources of more than 700 MMb of light oil and 3 Tcfg, as estimated by Subsea IQ.

A recent Campos Basin prospectivity evaluation carried out by Spectrum has identified a significant number of untested pre-salt structures in open acreage, a very exciting prospect for any company looking to explore in this basin, as it is strongly rumored that this area will be offered in the upcoming licensing round. Not only is large additional pre- and post-salt potential identified on available 2D and 3D datasets, but also potentially huge basin floor fans lying over mature Aptian source rock can be seen beyond the salt dome province on the only dataset available with coverage over this area.

Campos Basin: Seismic Line

The ‘perfect pre-salt play system’ on Spectrum 2D PSDM in depth.

Spectrum’s unique regional dataset, which covers the Campos Basin, has the imaging quality needed to study pre-salt discoveries and leads in detail but, more importantly, provides the industry with an unrivaled dataset which allows a complete regional picture to be obtained, with the added bonus of revealing huge potential beyond the salt dome province.

Spectrum understand that high quality seismic data is essential for both detailed and regional evaluation of proven pre-salt and post-salt plays, and indicates huge untested pre-salt potential in one of the most productive basins in the world. Therefore in Q3 2016 Spectrum began the acquisition of a broadband long-streamer survey covering the salt basin and out to the thick clastic sequence beyond the salt, where an abundance of high amplitude anomalies reveal a future oil domain of astonishing promise.
