    • The invention relates to a process for two separate seismic crews to work in proximity to one another that would otherwise require expensive time sharing where one crew is a conventional seismic acquisition system and the other is a phase encoded seismic acquisition system. Typically, each recording system would receive seismic energy from the other that neither data set would be very useful. The invention primarily envisions some collaboration between the crews where each adjusts its sweeps to comprise a different time duration so that the energy the other crew's sources are distinguishable in the data set and easily eliminated therefrom. Distinctions may be further enhanced when the two crews use construct their sweeps so that each crew has a distinctly different start frequency and a distinctly different end frequency.
    • 本发明涉及一种用于两个独立地震工作人员彼此接近工作的过程,否则这些地面工作人员将需要昂贵的时间共享,其中一个机组人员是传统地震采集系统,另一个是相位编码地震采集系统。 通常,每个记录系统将从另一个记录系统接收地震能量,这两个数据集都不是非常有用的。 本发明主要设想船员之间的一些协作,其中每个船员之间的调整扫描包括不同的持续时间,使得其他船员的来源在数据集中是可区分的并且容易从其中消除的能量。 当两名乘员组织使用扫描结构,使每个乘务员具有明显不同的起始频率和明显不同的终点频率时,可以进一步提高区别。

    • 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.
    • 本发明涉及处理地震数据,其包括来自至少两个源的信号,通常三个或四个源,其中源分离对于地球物理分析是必需的。 具体地说,本发明是一种用于在反转之前对数据进行校正的处理,其中提供校正以校正地球的滤波效果。 地球是一种不均匀的地震传播器,其导致与源和接收机方位角和偏移量相关的地震能量小波的变形,这使得复合数据内的源特定数据的识别难以识别。 计算地球反应并纠正地球对小波的影响提供了更多的分辨率和更清晰的结果数据和更好的地球物理解释。
