The Use of Electrical Resistivity to Determine Porosity of Marine Sediments

Abstract

A method using electrical resistivity measurements to determine the in situ porosity of marine sediments was investigated in the designed, fabricated and tested. Formation Factor-porosity relationships determined in the laboratory for three clays (kaolinite, illite, and montmorillonite), Providence silt, four sands, and four marine sediments showed that porosity was predicted within plus or minus 2 percent. The Formation Factors ranged from 1.1 to 5.9 while porosity ranged from 26 to 93 recent. The particle size and distribution influenced the electrical resistivity of these sediments independent of porosity while particle shape did not.
