Determination techniques of Archie's parameters: A, m and n in heterogeneous reservoirs

The determination of water saturation in a heterogeneous reservoir is becoming more challenging, as Archie's equation is only suitable for clean homogeneous formation and Archie's parameters are highly dependent on the properties of the rock. This study focuses on the measurement of Archie...
