$5\mathrm{.}5$ Six cylindrical core plugs of $2\mathrm{.}54$cm diameter and $3\mathrm{.}81$cm length were taken from an Alaskan North Slope reservoir. After cleaning, porosities of all the plugs were measured by a helium porosimeter. Subsequently, all samples were fully saturated with a $0\mathrm{.}07\backslash$Omega m brine such that S$\_($w$)=1.$ Each sample was placed in a resistivity apparatus, and $\backslash$Delta V values were measured for a current flow of $0\mathrm{.}01$A $.$ Determine the formation factor F $,$ for each core plug, and estimate parameters a and m for Archie's formation factor equation. $[[$Core Plug,$($Fraction$),\backslash$Delta V$($V$)$
