1) Six cylindrical core plugs of 2.54 cm diameter and 3.81 cm length were taken from an Alaskan North Slope reservoir. After cleaning porosities of all plugs were measured by

a helium porosimeter. Subsequently, all samples were fully saturated with a 0.07 Qm brine such that, Sw-1. Each sample was placed in a resistivity apparatus and voltage (E) values were measured for current flow of0.01 A. Determine the formation factor F, for each core plug and estimate parameters a and m for archie's formulation factor equation.
