F K Filtering For Seismic Data Processing The key steps are 1) transforming to f k, 2) defining velocity filters, 3) multiplying data in pass reject zones, download as a pptx, pdf or view online for free. To accomplish this you can use the f k, or pie slice, filter in which the range of apparent velocities can be selected and removed to eliminate this linear noise.
F K Filtering For Seismic Data Processing Pptx The objective is to enhance the signal to noise ratio and obtain an accurate image of the subsurface by using these techniques to attenuate noise and correctly position seismic reflections. A two dimensional fourier transform over time and space is called an f k (or k f) transform where f is the frequency (fourier transform over time) and k refers to wave number (fourier transform over space). Seismic toolbox: bowpy development of a toolbox applicable to seismological array data using body waves, containing f k methods for data reconstruction and filtering. Filtering can be used to separate out a particular seismic event, which is shown on the seismic section, using apparent velocity as the selection criterion. each straight line event, like a direct wave, refracted wave or surface wave, has a particular apparent velocity.

The procedure for carrying out f k filtering is provided in the flow chart, below left. the final diagram shows four shallow marine records before and after f k filtering to remove coherent linear noise.

The procedure for carrying out f k filtering is provided in the flow chart, below left. the final diagram shows four shallow marine records before and after f k filtering to remove coherent linear noise. Our goal is to give you the experience and tools to continue exploring the concepts of seismic data processing on your own. this primer covers all processing steps necessary to produce a time migrated section from a 2 d seismic line.
