... kinds of noises once for all. Under the framework of sparse representation, the denoising effect is closely related to the chosen dictionary, a set of base functions. In general, the stronger the correlation between signal and dictionary is, the better denoising effect will reach. As a result, a new...

... of Tuscaloosa Marine Shale (TMS) formation. The TOC values in the well location have been calculated using Passey’s ΔLogR method which later used for multiattribute seismic analysis over the survey area. Using three seismic attributes, we have found a validation correlation coefficient of 81% while running...
