LONDON – New Age Energy Algoa has issued results of reprocessed 2D seismic data over the Algoa-Gamtoos license offshore South Africa.
This is adjacent to the Total-operated blocks 11B/12B, containing the Brulpadda and Luiperd discoveries in the Outeniqua basin.
Reprocessing covered 4,500 line-km of 2D seismic, incorporating data already owned by the partners and further data acquired from the Petroleum Authority of South Africa, including tie lines from the deepwater Brulpadda gas-condensate discovery to the Algoa-Gamtoos area.
Results were combined with two post-stack merged 3D seismic surveys in the Algoa basin. PGS performed the work, the priority being to develop a time and phase-matched dataset covering the Gamtoos basin and the deepwater (Outeniqua basin) section of the license area.
Tower Resources, which is present in the concession via its subsidiary Rift Petroleum, said the results show overall improvement in bandwidth, de-noise and imaging.
Structural imaging too is clearer, gathers are significantly flatter with less noise, and results have increased confidence in the amplitude versus offset analysis.
In the deepwater (Outeniqua basin) section of the license New Age has identified a deeper level slope (as seen at Brulpadda) and three separate reservoir targets:
- A shallow section with 470 MMboe Pmean recoverable resources
- A deeper slope section (231 MMboe recoverable)
- A basin floor fan section (710 MMboe).
In addition, New Age has spotted a new lead in a submarine fan complex in the shallow-water Gamtoos area of the license, which it believes could hold 135 MMboe.
