摘要： Coherency analysis, such as semblance scan or stacking amplitude, is used to locate diffractors. Once the diffractors are located, noise energy originating from the diffractors is minimized. Locations of each diffractor are determined by comparing the lateral coherency of the received amplitudes that each assumed diffractor position generates.

摘要： Coherency analysis, such as semblance scan or stacking amplitude, is used to locate diffractors. This is done utilizing traces of a recorded 3-D marine survey with one or more cables. Locations of each diffractor are determined by comparing the lateral coherency of the received amplitudes that each assumed diffractor position generates. Once the diffractors are located, noise energy originating from the diffractors is minimized.

摘要： A method for seismic surveying includes disposing a plurality of seismic sensors in a selected pattern above an area of the Earth's subsurface to be evaluated. A seismic energy source is repeatedly actuated proximate the seismic sensors. Signals generated by the seismic sensors, indexed in time with respect to each actuation of the seismic energy source are recorded. The recorded signals are processed to generate an image corresponding to at least one point in the subsurface. The processing includes stacking recordings from each sensor for a plurality of actuations of the source and beam steering a response of the seismic sensors such that the at least one point is equivalent to a focal point of a response of the plurality of sensors.

摘要： Apparatus for correcting measurement errors due to cycle skipping in acoustic-wave transit time measurements.The measurement made during sequence N-1 is stored in an auxiliary memory and compared with the next measurement (sequence N). If the difference between the two successive measurements is smaller than a given fraction of the average period of the acoustic waves used, the measurement of sequence N is transmitted to a measurement memory and recorded. Otherwise, it is the last measurement considered good which is recorded. Moreover, in case of erroneous measurement, the transfer of the control signal for the gain applied to the reception signal is stopped and the gain remains at its former value.Significant improvement in the quality of acoustic well-logging recordings is achieved.

摘要： A method is described for seismic imaging that may include receiving digital seismic data; processing the digital seismic data to create a digital seismic image in a seismic domain; flattening the digital seismic image to generate a digital flattened image; identifying artifacts in the digital flattened image; transforming the artifacts back into the seismic domain; and reprocessing the digital seismic data based on the artifacts in the seismic domain to generate a digital image with reduced artifacts. The method may be executed by a computer system.

摘要： The invention relates to processing seismic data that includes signals from at least two sources and typically three or four sources where source separation is necessary for geophysical analysis. Specifically, the present invention is a process for correcting data prior to inversion where the correction is provided to correct for the filtering effect of the earth. The earth is a non-homogenous seismic propagator that causes distortions of wavelets of seismic energy related to the source and receiver azimuth and offset that makes the identification of source specific data within the composite data harder to identify. Computing an earth response and correcting for the effects of the earth on the wavelets provides for more resolution and more clarity in the resulting data and better geophysical interpretation.

摘要： Correcting seismograms to compensate for absorption or dissipative effects that occur in the earth. In one implementation, a ratio of traveltime (t) to absorption parameter (Q) may be computed for each seismogram. The ratio may be referred to as R. Further, the ratio may be computed for a predetermined set of traveltimes. As a result, a system of linear equations may be generated, where each ratio is represented by a linear equation having a number of unknown components. The system of linear equations may then be solved for the unknown components. The solved components may then be recombined or added to generate an estimate of R. In one implementation, only a portion of the solved components may be added. The seismograms may then be corrected using the estimate of R. As such, the seismograms may be corrected for absorption effects in a surface consistent manner.
摘要翻译：校正地震图以补偿地球中发生的吸收或耗散效应。在一个实施方案中，可以针对每个地震图计算旅行时间（t）与吸收参数（Q）的比率。该比率可以被称为R.此外，可以针对预定的行程组计算该比率。结果，可以产生线性方程组，其中每个比率由具有多个未知分量的线性方程表示。然后可以为未知组件求解线性方程组。然后可以将所解决的组件重新组合或添加以产生R的估计。在一个实现中，可以仅添加一部分被求解的组件。然后可以使用R的估计来校正地震图。因此，可以以表面一致的方式校正地震图的吸收效应。
