A [[log]] combination and computation procedure for calculating the [[resistivity]] of the [[invaded zone]], the [[true resistivity]], the [[diameter of invasion]], and the [[water saturation]] based on a [[dual induction log|dual induction-laterolog]] and a [[porosity]] log.

For Baker-Atlas: a "Small-SLAM" or "Mini-SLAM" or "Little-SLAM" is a service combination comprising [[Density]], [[Neutron]] and [[resistivity_log|Resistivity]] measurements (as well as [[gamma-ray_log|Gamma-Ray]]), where "Resistivity" can mean a measurement in resistive or conductive environment to define the [[resistivity]] of the formation.
