Spatial Bandpass filter
S-01415
As a Tullow Geophysicist, I wish to be able to apply a spatial band-pass filter to my traces for basic noise removal.
PreDev Notes:
Will assume data is regularised
Spatial means on surface, so il/xl grid
Should follow temporal bandpass template, which applies a butterworth style filter and users can define:
- The cutoff frequency
- Type of filter (highness, lowpass, bandpass, bandstop)
- Whether to apply filter in frequency or temporal domain (while frequency domain is easier ie FFT, time domain helps prevent leakage)
Difficulty will be in communication.

Success Criteria:
- Able to apply 3D spatial filter to gather/file
- Works on a regularised grid
Tasks:
-
Get and compile NFFT -
Create Test Set Data/System test -
Spatial filter -
Multi-dimensional filtering (in prog) -
Unit tests (in prog)
