I think we need a decent presentation from GBP once the PEL 94 analysis is completed. I also want to know if the reservoirs in PEL 30, 37, 44 are:
1. Located beneath an overlying sand zone?
2. How many licences/prospects at these shallower depths across the Walvis Basin are connected with the same overlying sand?
3. Is the sand seal described on PEL 44 also the most likely zone to become a carrier bed should it fail with the known regional shale seal sitting directly above?
4. If so, is that sand zone / possible carrier bed represented by the ‘Exxon enters, defining moment pancontinental’ article image?
5. Is it also the as described ‘restricted channel’?
6. Are the conduits/thief channels on Cormorant PEL 37 located within an overlying sand/carrier bed above the reservoir now being talked up as an up dip seal in PEL 44?
7. Did the Wingat-1 well hit the very same sand channel? ‘light 38 to 42 degree API oil from thin sands of undisclosed age.
8. Just how important is the regional structural closure provided by the Walvis Ridge?
Carrier beds
The carrier formation is defined as a lithologic formation, beneath a regional seal, that offers the paths for hydrocarbon migration in a certain geological period when hydrocarbon migration process happened. Such a carrier formation may contain a few or multitudinous permeable geological bodies, hydraulically connected among themselves.
