Any petroleum geologists out there...
Any petroleum geologists out there...who could comment further on this?? What are the chances of decent recovery rates?
"A moderate to highaverage VClay (clay volume) value of 47.7% over this interval mayindicate a relatively high ductility. If a formation is too ductile, itcan prove difficult to generate a large fracture network necessary toproduce the reservoir at commercial rates. However, cuttings analysisreveal the ubiquitous presence of slickensides in the rocks, whichindicate these shales may have a tendency to break on micro-slippageplanes along which the rock was deformed during its emplacement as anallochthon (transported unit). Further understanding of this issue willbe one of the objectives of core analysis from the current 3K-39 well,where 50 meters of core over five gross intervals was collected. Inoutcrop around the periphery of Port au Port Bay, Green Point shalesare seen to be highly fractured and rubbly.
NuTech cautions that although the permeability cutoff used for payanalysis is similar to that used in the Eagle Ford Shale, and is rootedin thousands of shale log analyses in basins worldwide, it lacks localcalibration for this formation in western Newfoundland. Shoal Pointreiterates that one of the objectives of the current 3K-39 well is thecollection of rock data from core that can be used as an input tocalibrate petrophysical data from the new 3K-39 well."
