摘要： A method for enhancing a physical parameter map in a zone of a seismic image. The dip of points of the image is obtained. For one of these points, called second point, a correction factor of a physical parameter is obtained with a residual move-out algorithm from a common image gather. A first point is selected on a line substantially perpendicular to the dip at the second point. The selection, involves at least one parameter among whether the difference between the dip at the second point and the dip at the first point is below a first preset value; and the spacing between the first and the second point is below a second preset value. An inversion algorithm gives a corrected interval value of the physical parameter to update the physical parameter map.

摘要： Seismic data representing the propagation of seismic energy through a geologic volume of interest is processed. The seismic energy propagates through the geologic volume of interest from one or more source locations at or near the geologic volume of interest to one or more detector locations at or near the geologic volume of interest. In processing the seismic data, the seismic energy is modeled as beams (e.g., Gaussian beams). The processing includes determining a filter for the seismic data that attenuates aliasing which may be present in the seismic data due to spacing between detector locations.

摘要： In one embodiment of the present invention, a method of generating a zero-offset trace, at a zero-offset location on a processing plane, for a time sampled recording is provided. The time sampled recording has a source and receiver, and a source coordinate and a receiver coordinate associated therewith. The time sampled recording also has an amplitude and a sampled time associated therewith. The method comprises reading the source and receiver coordinates and determining an ellipsoid dependant upon the source-receiver offset, the sampled time, and the velocity of the medium. The ellipsoid has the source as one focus and the receiver as the other focus. The method further comprises determining a set of normal points on the ellipsoid and determining the distance between each of the normal points and the zero-offset trace location and dividing twice the distance by the velocity of the medium, wherein the zero-offset travel time for each normal point is determined. The method further comprises assigning an amplitude to each zero-offset travel time, wherein a zero-offset trace is generated.

摘要： In a preferred embodiment of the present invention, methods are provided for Kirchhoff-migrating seismic data using a parallel computer. The methods of the present invention preferably use a multiprocessor machine that is interconnected to form a hypercube. The presently preferred method is to build up one or more migrated output traces in each processor (node) designated as a "migration" processor, as input traces are passed from migration node to migration node along a nearest-neighbor chain. When an output trace is completed, it is sent by a migration node to storage via an appropriate I/O processor and the migration node beings building a new output trace. There is essentially no limit to the length of seismic line which can be so migrated. Alternatively, the input traces may be held in the migration nodes and the output traces passed from node to node along a nearest-neighbor chain, or the input and output traces may be passed in opposite directions along the chain. Further, the use of multiple migration chains allows for efficient operation over a wide range of number of available processors.
摘要翻译：在本发明的优选实施例中，使用并行计算机为基尔霍夫迁移地震数据提供了方法。本发明的方法优选地使用互连以形成超立方体的多处理器机器。当前优选的方法是在被指定为“迁移”处理器的每个处理器（节点）中建立一个或多个迁移的输出迹线，因为输入跟踪沿着最近邻链路从迁移节点传递到迁移节点。当输出跟踪完成时，迁移节点通过适当的I / O处理器发送到存储器，并且迁移节点生成新的输出跟踪。地震线的长度基本上没有限制，可以这样迁移。或者，输入轨迹可以保持在迁移节点中，并且输出轨迹沿着最近邻链链从节点传递到节点，或者输入和输出轨迹可以沿着链沿相反方向传递。此外，使用多个迁移链可以在广泛的可用处理器范围内进行有效的操作。

摘要： A method for carrying out dip moveout correction on seismic data which provides true-amplitude seismic images is provided. A calibration process is used to design a set of filters that correct the seismic amplitudes during dip moveout correction so as to provide true-amplitude imaging. These filtrs can be designed and applied in any known implementation of dip-moveout, in three or two dimensions.

摘要： Method for optimal stacking of seismic images to remove noise and enhance signals in seismic images (101) outputted from a Reverse Time Migration (RTM) imaging process. Dip information is calculated (102) and then sorted by image point (104), for each seismic image to be stacked. A dominant dip and azimuth is determined at each image point (106), and only those events are stacked (107). If the image is still noisy or lacking in detail (108), the process may be iterated (109) to improve the selection of most likely dip and azimuth.

摘要： Method for estimating reflector dips in a window of post stack image traces (51) of seismic data for use in velocity tomography (57). The method iteratively (56) flattens (55) the image traces against a specified reference trace through the application of conjugate-gradient least-squares inversion (53). Different from other dip estimation methods which emphasize on strong-amplitude reflectors, the inventive method automatically inverts for the reflector dip for every grid point in the image window.
