Cementation exponent

Term · Oil and gas · MLC-T-OAG-000619

An empirical parameter, denoted as 'm', used in Archie's equation to relate the formation resistivity factor to porosity. It accounts for the tortuosity and interconnectedness of the pore network within a rock. Typical values range from 1.8 to 2.2, with variations depending on the rock type and pore geometry.
