... ABSTRACT The seismic volumetric dip is widely used in the horizon and fault interpretation. One of the mostly used dip estimating method is the waveform similarity-scanning based dip estimation which can deliver the reliable dip estimation. However, the waveform similarity-scanning based...

... ABSTRACT This study presents a new method for accurate dip estimation based on the 3D curvature/flexure analysis of seismic waveforms in a seismic section/volume, denoted as the waveform curvature/flexure. Such waveform analysis is capable of measuring the most and least apparent variation...

... must be large to estimate smooth dip from the decimated data to guarantee the stability of inversion. In the later iterations, the smooth radius will be shortened in order to get more accurate dip estimation and good reconstruction result. We compare the proposed method and the well-known projection...

.... By low-pass filtering the under-sampled seismic data with a very low bound frequency, we can get a very precise dip estimation, which will make seislet transform capable for interpolating the aliased seismic data. In order to prepare the optimum local slope during iterations, we update the slope field...

... a semblancebased scan to estimate 3D dip. Barnes (1996, 2000a) presented an dip estimating method based on 3D complex trace analysis, while the estimate based on gradient structure tensor (GST) is also presented (Bakker et al, 1999). Luo proposed dip estimation based on weighted structure method (Luo, 2006...

... of this study was to create a method that gives a more complete model of the faults networks, and as such, involved a Sobel based edge detection algorithm for delineating amplitude discontinuities. Though, we also included a gradient decent dip estimation to capture the phase changing faults. When using...

... the location of all interfaces in the underground simultaneously. These types of processes are often referred to as automatic 3D (volume) dip estimation, as the output of the process usually is, for every sample in the volume, estimated formation dip in the x and y direction. This formation dip is often...
