Abstract
A method for producing borehole-compensated values from non-borehole-compensated measurement signals taken with a logging device in a borehole in earth formations, includes the following steps: producing a database that includes a multiplicity of data points, each data point representing a combination of formation parameters and borehole parameters, database input vectors representing multi-dimensional non-borehole-compensated model measurement values respectively associated with the data points, and database output vectors representing multi-dimensional borehole-compensated model measurement values respectively associated with the data points; deriving a multi-dimensional measurement signal vector from measurement signals taken with the logging device in the borehole; and interpolating the measurement signal vector using the database to obtain an interpolated output vector representative of borehole-compensated measurement signals.
