Abstract: A fuzzy computer basically includes a plurality of fuzzy membership function generator circuits, and a fuzzy inference engine for executing a predetermined fuzzy operation among fuzzy membership functions that have been generated. A fuzzy membership function is represented by electric signals distributed on a plurality of lines.
Abstract: A method for continuous velocity estimation of seismic data uses non-linear signal matching. Common depth point trace data is examined at selected offsets and non-linear signal matching is performed to derive moveout information from which the RMS and interval velocities may be further estimated. Non-linear signal matching for selected offsets of each CDP trace gather functions to derive characteristic match curve data at selected depths or travel time intervals. The match curve data inherently contains moveout information that relates to energy velocities for the particular trace position. Derived velocity data for selected time depths may then be output across a line of survey.
