Multilayer Bed Boundary Detection Technology provides an extended complex of directional electromagnetic (EM) measurements with an improved signal-to-noise ratio compared to the previous generation of remote boundary mapping technology. As a result of the processing of the obtained data, the inversion of EM measurements is calculated on the basis of the mathematical stochastic apparatus MC3. The apparatus allows to solve the inverse problem for multilayer models taking into account the bedding depth and electrical anisotropy of rocks, selecting the most stable solution.

The result of the inversion is a vertical section of resistivities that varies along the well trajectory. Multiple inversion provides informativity in complex geological conditions, with interlayers and localized geological elements, and stable mapping with less resistance contrasts [1, 2].
