Abstract:
1. A method for developing at least one template to use to remove noise from or interpret noise in a target data set of geophysical data, wherein the template is adapted to the target dataset, said method comprising: (a) transforming the target data using a selected complex-valued, directional, multi-resolution transform (“CDMT”) satisfying the Hilbert transform property at least approximately to obtain a set of expansion coefficients that are complex numbers having a magnitude and phase; (b) selecting an initial template representing noise in the target data set and transforming the initial template using said selected CDMT; (c) adapting the transformed template to the transformed target data by adjusting the template's expansion coefficients within allowed ranges of adjustment so as to better match the expansion coefficients of the target data set, thereby creating an adapted template; and (d) using the adapted template to suppress noise, further process, or interpret the target data set or other geophysical data in order to prospect for or produce hydrocarbons; wherein at least one of (a)-(c) are performed using a computer.
