WebPOCS interpolation is a simple and effective way to produce multi-dimensional interpolations that can de-alias seismic data well (Abma, 2009). While POCS should have at least half the traces live on the input, the POCS interpolation tends to be fairly robust in places where MWNI is difficult to parameterize. MWNI WebPOCS Interpolation. The POCS (projection onto convex sets) based interpolation method (Adorf 1993) is a conceptually simple, iterative scheme, directly applicable to regularly sampled observations with missing data, where the underlying continuous signal has a known (or assumed) fundamental period. The POCS method attempts to fill the data gaps …
WebMar 1, 2024 · Consequently, the new algorithm, which will be called IRCNN-FPOCS, has three advantages: (1) supports high-performance seismic interpolation with deep priors; (2) is interpretable; and 3) alleviates the problem of insufficient training data for the seismic field. WebApr 1, 2024 · To address the problems incurred by the presence of noise, interference, and gaps in real measured potential field data, we proposed a method for the simultaneous interpolation, border padding, and denoising of potential field data using a POCS algorithm.
WebInterpolation acts as a random noise attenuator because it can only predict coherent energy, but there are already many processing tools to tackle random noise. Coherent noise, on …
WebSep 27, 2024 · Geophysical data interpolation has attracted much attention in the past decades. While a variety of methods are well established for either regularly sampled or irregularly sampled multi-channel data, an effective method for interpolating extremely sparse data samples is still highly demanded.
