摘要： Disclosed are a process and a system which relate to well logging, to converting logs to dips of subsurface formations and to producing a new type of a map record of dips. The map record conforms to a plane which is transverse to the borehole and contains a number of map line representations the position of each of which conforms to a range of dips consistent with the displacement between two similar reflections on respective well logging signals. The displacements relate to reflections on logging signals at borehole depths within an interval which is small as compared to the depth of the entire borehole, and the predominant locus of intersections of such line representations on the map record determines a likely dip of a subsurface feature which is in the borehole depth interval of interest.
