Term · Oil and gas · MLC-T-OAG-002245

The cementation exponent in Archie's equation, which describes the relationship between formation resistivity, porosity, and water saturation. It accounts for the tortuosity and connectivity of the pore network within a rock. The value of 'm' typically ranges from 1.8 to 2.2 for sandstones and carbonates, but can vary with rock type and pore geometry.
