Spectrum : New Spectrum 2D Seismic to Refine Understanding of Hydrocarbon Potential Offshore Mozambique

Spectrum is set to bolster its extensive Multi-Client library offshore Africa through the commencement of a 2D seismic survey offshore Mozambique on behalf of the Institute of National Petroleum (INP) and in anticipation of future license rounds.

This new 2D seismic programme of up to 19,000 km will be undertaken utilising a 10,000 m offset with continuous recording to enable extended recording lengths and high fold data. It is being acquired to complement existing 2013 seismic located in the Mozambique Channel area which is also available through Spectrum. Gravity and magnetic data will be acquired in conjunction with seismic data to allow for independent verification of structure.

The survey is specifically designed to image the subsurface potential in the southern Rovuma Basin and the western flanks of the Kerimbas Graben, west of the Davie Fracture Zone, providing a more detailed understanding of the prospectivity in this region. Potential targets, identified following recent studies in the area, include Cretaceous and Tertiary turbidites and buried canyon plays. The survey will also image the syn-rift structures and Late Cretaceous pro-delta stacked turbidite sequences in the northeast Zambezi Depression.

Spectrum EVP of the Africa Region, Graham Mayhew commented, 'This new Multi-Client survey will play a key role in refining our understanding of the hydrocarbon potential offshore Mozambique between the Southern Rovuma Basin and the North-East of the Zambezi Delta, and accelerate exploration in an area considered to be significantly more oil-prone. In addition the data will also provide the basis for future license rounds as planned by INP.'

The data will be processed with PSTM, PSDM and Broadband products with first deliveries in early Q2 2018. This survey will be carried out in partnership with Western Geco and is supported by Industry funding.
