3.8 Following CT scanning, data are available for a chalk core plug from the North Sea area. The core plug is scanned at equal distance for 9 different slices. The second column provides the CT numbers for a clean sample (denoted as air ref), whereas the third column provides the CT numbers for a 100% brine-saturated sample (denoted as water ref). CT number for pure water is 32 HU and -1000 HU for air. Calculate the porosities of each slice of this core plug.
