Question

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.
