A method and system for geosteering may generate a misfit function using a spline function. The misfit function may be used to accurately map errors or differences between TVD-based measurement data for one or more reference wells and MD-based measurement data collected during drilling of a subject well, in order to accurately determine a stratigraphic location of the subject well.

Geosteering methods and systems for improved drilling performance

Systems and methods for automated filtering and normalization of logging data for improved drilling performance may enable smoothing and amplitude scaling of log data for meaningful comparison and analysis without scaling artefacts. The logging data may be collected from downhole sensors or may be recorded by a control system used for drilling. A computer implemented method may enable industrial scale automated filtering and normalization of logging data, including calibration to a known standard. In particular, the filtering and normalization may be used for stratigraphic analysis to correlate true vertical depth to measured depth along a wellbore.
