摘要： A method is described for a manner of geologic analysis using seismic data. The method includes steps to produce improved amplitude versus angle (AVA) information that may be used for analysis of geologic features of interest including estimation of pore fluid content. The method assesses the probability of hydrocarbons in a subterranean reservoir based on seismic amplitude variations along offsets or angles for portions of a seismic horizon. The method may be executed by a computer system.

摘要： Geologic information may be extracted from multiple offset stacks and/or angle stacks. Offset stacks and/or angle stacks may be received that represent energy that has propagated through a geologic volume of interest from energy sources to energy receivers. Attribute volumes associated with individual source-receiver offsets and/or source-receiver angles may be determined based on corresponding offset stacks and/or angle stacks. For individual offset stacks or angle stacks, corresponding sets of geologic features represented in the attribute volumes may be identified. The sets of geologic features corresponding to the different offset stacks and/or angle stacks to may be compared to determine discrepancies and/or similarities between the sets of geologic features corresponding to the different offset stacks and/or angle stacks. Stratigraphic interpretations, stratigraphic predictions, and/or other interpretations and/or predictions may be determined based on causes of the discrepancies and/or similarities.

摘要： A method of assessing a hydrocarbon source rock candidate uses seismic data for a region of the Earth. The data are analysed to determine the presence, thickness and lateral extent of candidate source rock based on the knowledge of the seismic behaviour of hydrocarbon source rocks. An estimate is provided of the organic content of the candidate source rock from acoustic impedance. An estimate of the hydrocarbon generation potential of the candidate source rock is then provided from the thickness and lateral extent of the candidate source rock and from the estimate of the organic content.

摘要： This patent delineates methods for quantifying and mitigating dip-induced azimuthal AVO effects in seismic fracture detection using Azimuthal AVO analysis by accurately accounting for the divergence correction and azimuthal dependence of the reflection angle. Solutions are provided for three cases: (1) dipping isotropic reservoirs; (2) anisotropic reservoirs with fractures aligned in arbitrary direction; and (3) anisotropic reservoirs where vertical fractures are aligned perpendicular to the dip direction.

摘要： The present invention is directed to generating moveout data for a gather with reduced or substantially eliminated stretch and with improved resolution of potentially overlapping events. In one embodiment, a zero offset trace is obtained and a phase information for the zero offset trace is substituted into phase information for each of the offset traces to perform a phase-based moveout. The zero offset trace may be obtained by a block move sum process and that process may be enhanced for improved resolution of overlapping events. The phase moveout data may be used for analysis of offset dependent relationships such as AVO. Additionally, the phase offset data may be stacked to obtain high signal to noise ratio data for further seismic analysis.

摘要： The present invention provides for a method and apparatus for seismic data processing. Prestack seismic data is obtained that contains a plurality of reflectors. Non-parallel moveout of the plurality of reflectors is utilized to determine a source wavelet using an L2-Norm and a reflectivity parameter using an L1-Norm. The source wavelet and reflectivity parameters can be determined simultaneously. Source and reflectivity determination may further comprise minimization of a model objective function. The model objective function may be a function of at least one of i) said source wavelet, ii) a gradient parameter and iii) an intercept parameter. An AVO intercept and gradient parameters can be determined using the determined source wavelet and reflectivity parameter. Constraints may be placed on parameters to ensure physically realistic solutions.

摘要： The present invention provides methods for processing and displaying seismic data to emphasize potential hydrocarbon bearing strata. The methods treat measured attributes from the seismic data as components of a vector, estimate a background vector which represents uninteresting geologic behavior, and then form at least one new attribute which quantifies departures from this uninteresting behavior. The new attributes(s) and other attributes are then appropriately displayed.
