RILM
SchlumbergerS/mMedium Induction Conductivity (Raw)
The raw medium-induction conductivity before calibration to the medium resistivity — the unprocessed medium-array conductivity, complementing the raw deep channel for invasion analysis and re-processing.

How it's measured
The medium induction array's raw measured conductivity, before the skin-effect and calibration corrections that produce the medium resistivity ILM.
How it's used
A QC and intermediate channel behind the medium resistivity, used with the raw deep conductivity to trace or re-derive the invasion profile.
Common gotchas
Raw and uncalibrated — not for direct interpretation. Prefer the medium resistivity (ILM) for analysis; keep RILM for QC and re-processing.
