Abstract
  Water saturation and cation exchange capacity are the most significant parameters used to calculate a hydrocarbon zone potential. In clean formations, by applying the famous Archie model, which assumes that in the formation the only electric conductor is the formation water, the water saturation can ...  Read More

http://dx.doi.org/10.22050/ijogst.2014.6030

Abstract
  Petrophysical parameters such as porosity, water and oil saturations, formation resistivity factor, etc. describe the storage capability of the porous media or the capacity of rocks to hold fluids. The modified Archie’s equation    . / . , also called the saturation equation, is used ...  Read More
