MAPUTO– The French geophysical services company, Compagnie Generale de Geophysique (CGG), says it has completed the acquisition of 15,400 square kilometres of 3-D marine seismic data in the outer Zambezi River Delta Basin in central Mozambique.

The survey area covers blocks Z5-C and Z5-D and surrounding non-held acreage in the Mozambique Channel under an agreement reached with Mozambique’s National Petroleum Institute (INP) in 2017. The data will provide greatly increased knowledge of the hydrocarbon potential of the Zambezi Delta, providing oil and gas companies with the information they need to pursue their activities, according to CGG.

The initial data will be available in the last quarter of 2018 in anticipation of a licensing round during 2019. The final data sets will be made available in the last quarter of next year.

The company’s chief executive, Sophie Zurquiyah, said in a statement that the data will support INP’s promotion of the potential in the deep-water Zambezi Delta Basin and the west flank of the Beira High area.

This full package will also provide interested companies with the information required “to confidently de-risk the full Paleozoic, Mesozoic and Cenozoic series in this exciting new exploration area, said CGG.

In October 2015 the INP awarded the contracts to explore Blocks Z5-C and Z5-D to a partnership between the US energy giant ExxonMobil and Russian company Rosneft.

ExxonMobil will be the operator, with a 60 per cent stake, whilst Rosneft has a 20 per cent share. The remaining 20 per cent stake is held by Mozambique’s National Hydrocarbon Company (ENH).

So far, Mozambique has known reserves estimated at 200 trillion cubic feet of natural gas in the Rovuma Basin, off the coast of the northern province of Cabo Delgado.
