Abstract
A dipmeter signal processing method and system are disclosed, wherein portions of at least three are matched, utilizing correlation intervals, to derive a plurality of possible offsets. For each of the offsets, the spatial coordinates are defined of an associated vector parallel to an implicit bedding plane. The coordinates are utilized to combine nonparallel vectors to generate a plurality of dips. The dips that substantially repeat for a given depth or repeat from one depth level to the next within a given depth zone are retained to retain a single dip for each depth. A display is then outputted of each dip at each depth.
