ABSTRACT:
A plurality of formation resistivity logging data sets are generated along a borehole. From the data formation dip values are preliminarily determined at different elevations along the borehole. The dip values are combined for each borehole elevation of interest in a functional relationship utilizing a variable scatter parameter related to dip direction and magnitude variations whereby the resulting dip value at each elevation is taken as the corrected value. The variable scatter parameter may be selectively varied to produce variable representations as desired of formation dip, including visual representations. These variable representations may range from those excluding dip data points inconsistent with prevailing geological interpretation patterns and thereby exhibiting progressively less scatter to those representations including more available and possible dip values with scatter to be interpreted.
