Abstract:
A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for accurately locating a particular event of a plurality of events in a particular seismic trace among a plurality of seismic traces, said method steps comprising the steps of:(a) locating a best sample of said particular seismic trace that lies within a search window, the best sample most accurately representing said particular event within said search window;(b) locating other samples around the best sample in said search window including a first adjacent sample on one side of the best sample and a second adjacent sample on the other side of the best sample;(c) selecting either said first adjacent sample or said second adjacent sample,(d) performing a bisection operation and an amplitude determination operation between the best sample and the adjacent sample selected during the selecting step (c) to thereby determine and locate said particular event of said plurality of events in said particular seismic trace among said plurality of seismic traces.
