Also, the resistivity-degrading effects of relative dip seen by the tool are often underestimated.
Relative dip is a function of both true structural dip and borehole deviation.
The bottom line is that thin beds can be easily missed and most formations will be under-valued by water saturation calculations based on the masked resistivity. DCX Processing DCX Processing is an auxiliary service to XHR induction logging that allows MPI to provide their customers with the best possible measurement of formation resistivity. This can be done because the XHR measurement system was designed to allow for variations from the horizontal bedding model. The default XHR formation model is formation layering perpendicular to the borehole. The output is the dipping bed resistivity solution.
