Having asked a question elsewhere, on the sample selection logic, and receiving a credible response. I though others would also find it interesting. My take is now modified, the next 13 samples will tell more than the first 5.

Selecting the intervals to be cored is actually done on purpose at the well site after open hole logging. The geologist / log analyst / petrophysicist always choses the good, the bad, and the ugly so that they can obtain exact reservoir physical parameters and calibrate the log data. Tight, low porosity rock have different Log resistivity and density porosity from the good oil saturated rock and sometimes are difficult to differentiate. Also, some intervals may contain 100% water - they really need to know that! AND - some samples may only contain natural gas and will not show oil indicators and fluorescence - the rock would look hydrocarbon dead. The choice to obtain a lab "quick look" at 5 samples allows the petrophysicist and the log analyst to jump start, as it were, the entire geological / petrophysical model. So - they can now see on the logs the good, the bad, and the ugly with confidence.
The other 13 samples had good oil saturation and as such will receive the special "Dean Stark" Lab process. This will focus on and define the "oil reservoirs."
