The optimal value of IR (ρ opt ir) is taken at a point on the
curve, which is located at a distance – L p / 2 from the middle of the
reservoir down to a consistent probe or up to a inverse probe.

where: S – area against the reservoir with covered by the IR curve
- without screening interval (L p).
Maximum meaning ρ ir located at the base or in the roof of
the reservoir.
