Interesting article there J (Exxon and Guyana). Exxon have promised to use there advanced technology to explore those newly acquired blocks.
That SpectrumGeo article is a heavy read :-) My take on it is the importance of some form of structural trap as a primary key to success.
"However, with strikingly similar characteristics to the Brulpadda discovery, in relatively shallow water settings, leads and prospects comprising basin floor fans ponded against major transform fault ridges have been identified from South Africa up to Mozambique setting off the chase for acreage in this new exploration trend."
Reminder..
Albian-Aptian, shallow marine carbonate reservoirs, the main targets at Gemsbok, Lion, Dik Dik and Welwitschia Deep, are present in the wells 1811/05-1 (Tapir South-1), 1911/15-1 and 1911/10-1, where the reservoir quality is good. This reservoir is mapped in large, dip and fault-closed structural traps in Global’s prospects.
I don’t see a difference between a ridge acting as a structural trap and a fault acting as a structural trap for oil accumilation?
However, Choje from lead to prospect?
"Choje is of particular interest as it is interpreted as a large, on-lapping upper Cretaceous fan on the eastern flank of the Gemsbok high and so consequently adds another potential level of prospectivity to the greater Gemsbok prospect area."
Is it not a Basin floor fan ponded against a fault as described above ref a new exploration trend?
