MACHINE, PROGRAM PRODUCT AND METHOD TO DETERMINE A FIRST ARRIVAL OF A SEISMIC TRACE |
摘要 |
<p>Embodiments of a machine, program product and computer implemented method to perform a process of picking an initial first arrival from at least one trace of the plurality of seismic traces and a process of refining the initial first arrival pick based upon a comparison of the initial first arrival pick with first arrival pick of adjacent traces is disclosed. Such embodiments perform the steps of: centering a main time window around each of the plurality of possible first arrivals for the seismic traces, setting a start of the time window to zero, transforming the plurality traces into a plurality of peak spike traces; dividing the main window into a plurality of sub-windows; comparing each of the plurality of peak spikes in the sub-window, determining the first arrivals, and determining if the first arrival is a desired pick.</p> |
