... within a given 3D seismic survey. In this paper, we modify a one-dimensional Kuwahara filter to identify upward fining and upward coarsening trends routinely used in the interpretation of gamma ray logs. We believe that by mapping such quantitative estimates that the interpreter will gain deeper insight...

... in various ways, using generalized linear inversion, Wiener filtering, wavelet and DEXP transformations, cross-correlation, and migration. We show that the resulting images from each of these approaches are equivalent to an upward continuation of the data, weighted by a (possibly) depth-dependent function...

... consists of two steps. First the recorded fields need to be decomposed in upwards and downwards decaying fields. This was first done by Amundsen et al. (2006) in CSEM. In our research an algorithm provided by Slob (2009) is used. This decomposition re- quires in 3D recordings of all four horizontal EM...

... limited interpretation value. In contrast, spectral skewness estimates quantify the asymmetry of the spectra which in turn can be correlated to multimodal behaviour due to channels, as well as the presence of upward fining, and upward coarsening sequencies.
