Synthetic deviation (SYNDEV) plots are derived from the treatment of dips as borehole deviations. These plots can bring out subtle geologic features not readily apparent on the standard tadpole plots or cumulative dip plots. The imaginary "borehole" can be displayed on plots similar to those in which borehole deviation is displayed. The suite of SYNDEV plots includes horizontal displacement plots, maps, sections, total azimuth plots, and azimuth difference plots. Horizontal displacement plots can substitute for cumulative dip plots, and displacement maps can substitute for dip-azimuth-vector plots, bringing these previously unrelated types of plots into a larger set of related analytical plots. Two additional plots useful in conjunction with SYNDEV plots are dip difference and full angular difference plots.
