Re: Apache Corporation Announces Major Oil Discovery in Block 58 Offshore Suriname at Kwaskwasi-1

Wish I had something useful to say here ken.
 
Not sure where on the Apache block the good well was drilled but their block is a little bit away from the long peninsula like permit of the Corantyne block held by cgx. The Demarera block further to the north west looks more "similar" in its sort of position relative to the coastline - but that does not mean a hell of a lot?
 
I am guessing that these plays are slope to sea floor turbidites, the slopes would be very channelised with thick within channel sand stacks and thinner lobes off the channel, while the sea floor turbidites would be flatter and far more widespread fans and lobes. Grain sizes too would be much finer distally than nearer shore?
 
From the sounds of things Apache may have found a really nice channel sand stack? This would give a very thick sand package, coarser average grain sizes and hence better permeability and a narrow ribbon like geometry of the individual sand bodies. What they may lack in width they make up for in length and so if there is a tall oil column above the bottom water there will be excellent reserves and a fabulous water drive pressure support.
 
The reported API oil gravity is a nice medium light black oil and so quite excellent quality. It is likely that other such turbidite channel sand stacks and lobes will have similar quality oil in them. Just need the excellent quality seismic definition to pick out where the most prospective channel sands and sand lobes may be developed and accurately drill into the heart of them in a good position above any potential oil water contacts. These sorts of things should be easily defined with modern seismic and software modelling. (I remember the excellent work done by Ikon science out of the UK for Oilexco and then Canadian Overseas and Exxon - not that that worked out very well for the latter off West Africa, but there was nothing wrong with the seismic and software modelling of the sands.) 
 
Finding sand rich turbidite channels is the key though - but finding decent sea floor fans and lobes is not too bad either - if they are not water filled.
 
While finding elephant fields - and far more fat warthogs - by close-ology is a good exploration technique - it is not foolproof (Again look at Canadian Offshore's experience with Exxon where they both thought they had a slam dunk!)
 
But at least we know the beasts are in the area - just got to catch a fat and promising looking one or two on the permitted areas! And ones with the right stratigraphic or structural closures and contacts.
 
Hopefully they will have some seismic with good looking model interpretations to show?
