vuggy porosity yakal and tindalo, page-2

I agree it looks good but the key is how well connected are the vugs.

If as expect Nido cored some of the oil zone and found that the core had lots of oil filled vugs I would be very concerned. As the drilling mud should have displaced the oil in the vugs. You only get oil filled vugs on surface in a core barrel if there is no permeability between the vugs.

End result lots of oil inplace but bugger all production.

Limestone reservoirs are always difficult to evaluate and develop, if Nido can cheaply produce these well they will have a nice little earner!!
