ABSTRACT:
A process for analyzing geological bedding plane data from a well, and plotting the cumulative dip angle and dip direction of the bedding planes with respect to depth. The cumulative dip angle may also be plotted with respect to sample numbers, which are a function of depth. The process further analyzes the cumulative dip data to produce a series of straight line approximations of various groupings of data. When these straight line approximations intercept, the interception often indicates a fault or unconformity at the location of the interception. The process further analyzes the cumulative dip plot by taking the first derivative of the plotted line. A stepwise shift in the derivative indicates an inflection point in the line, which often indicates a fault or unconformity. The process also plots the dip direction as the color or symbol of each point plotted and a color or symbol change often indicates a fault or unconformity.
