I spoke with a good contact of mine who works Gulf of Mexico plays. Operators today are now targeting thinner bedded silstone/very fine grain sandstone successions with permeabilities well below 100mD at depths of over 20,000 ft (Wei for comparison was 20,450 ft TVD). The era of only targeting massive bedded sandstones with permeabilities between 500mD-1000 mD are over in basins such as Gulf of Mexico. Companies have out of necessity become more agile and creative with being able to produce lower permeable/thinner bedded oil reservoirs!
Exxon JV obviously will target these massive bedded sandstones first in their Guyana plays... who wouldn't? But for northern Coreyne, these Santonian successions that are being "written off" by Frontera/CGX due to "lower permeability" is just nonsense. Someone will gladly buy these assets are bargain sale prices and make a killing one day... perhaps more than anything this crushes me to see. We should be getting full value for these oil successions in the Santonian and we aren't. Crinimal really... and if this is purely a ploy (still very possible) to manipulate share prices lower for accumulation purposes, then someone needs to be investigated and charged. Either way, this whole situation is just pure nonsense right now.
If offshore mature basins like GoM and North Sea can produce from lower permeable successions, sure as hell Guyana can as well. Please, if anyone on CGX/Frontera is reading this and has a functioning brain stem, please reconsider the tremendous folly currently unfolding.
