摘要： A device, medium and method for de-blending seismic data associated with a subsurface of the earth. The method includes receiving blended seismic data, wherein the blended seismic data includes traces having energies from two or more different shots that partially overlap; applying an apex-shifted radon transform (ASRT) to the blended seismic data to transform it from a first domain to a second domain; applying a mute processing for removing all shots except a first shot in the second domain; applying a reverse ASRT to the given shot to obtain the first shot in the first domain; and generating an image of the subsurface based on the first shot in the first domain. The procedure may be iteratively repeated to separate all shots.

摘要： An example method for displaying sonic logging data associated with a formation surrounding a borehole can include acquiring sonic data at a plurality of depths using an acoustic array located in the borehole and transforming the acquired sonic data from a time-space domain to a frequency-wave number domain at a limited number of discrete frequencies. The method can also include estimating slowness values at the limited number of discrete frequencies from the transformed sonic data, interpolating the estimated slowness values to obtain a projection of one or more slowness-frequency dispersions of the acquired sonic data and displaying the projection of the slowness-frequency dispersions. The projection of the slowness-frequency dispersions can include a plurality of color bands corresponding to each of the limited number of discrete frequencies.

摘要： A method for processing reflection seismic traces recorded for variable offsets, wherein a parabolic or hyperbolic RADON transformation is applied to collections d(t,x) of normal moveout (NMO) common mid-point seismic traces so that each collection d(t,x) is converted into a diagram ν(τ,q) on which each seismic event of d(t,x) is focused on an energy concentration area. The event focused on each of the energy concentration areas of the diagram ν(τ,q) is then reconstructed in linear form in a diagram D(τ,x2) by stacking along a straight line scanning a window centred on the apparent point centre of the energy concentration area in question, and covering the whole of said area. The method is useful for geophysical processing and particularly for determining intercept (Ro) and gradient (G) quantities by amplitude versus offset analysis (AVO).
