摘要： Generating an image of an interior of the Earth from a seismic survey using multiple sources. The multiple sources may be fired simultaneously and the data received by seismic sensors in the seismic survey may be decomposed so that seismic data generated by each of the multiple sources may be determined. Decomposing of the received data may be performed using frequency diverse basis functions and converting the data separation problem into an optimization problem, which can be a one-norm or zero-norm optimization problem in frequency-space domain. The decomposed data may be used to generate the image of the Earth's interior.

摘要： Methods and apparatuses for processing seismic data to generate images or determine properties of an interior section of the Earth. The seismic data is processed to filter coherent noise such as ground roll noise from seismic survey data. The noise is attenuated using 3D and/or 2D fan filters, which may have combined low-pass and band-pass filters derived from signal decomposition. The filters are designed with selected operator length, velocity bands of signals and noises and frequency range for a primary trace and adjacent traces within the operator length. The data is decomposed with the filters into signals and noises, and the noises are then filtered from the decomposed data. The process may be repeated for various frequencies and traces within the seismic data. The methods may be used for surveys that have either regular or irregular seismic receiver or seismic source positions.

摘要： Adaptive filtering method to remove ground roll from seismic data. In an M channel adaptive filter, weights W i are set using an adaptive algorithm based on seeking the minimum in the partial differential of cost function J. The cost function includes an expansion of the primary trace d into d = d g + Δd (where: d g is ground roll contribution and Δd = d sig + d ran , where d sig is the reflected signal component and d ran is a random noise component) and a corresponding expansion of the reference x into x = x g + Δx (where x g is ground roll contribution and Δx = x sig + x ran ; where x sig is a reflected signal component and x ran is a random noise component). The delta components are included in the denominator of cost function J to provide an optimal solution of the filter coefficients biased by the reflection signal and random noise is removed.

从地震数据中去除地面滚动的自适应滤波方法。在M通道自适应滤波器中，使用基于寻求成本函数J的偏微分中的最小值的自适应算法来设置权重W i。成本函数包括将主迹线d扩展为d = dg +Δd（其中：dg是地面滚转贡献，并且Δd= dg sig + d ran），其中d 是反射信号分量，并且d ran是随机噪声分量），并且参考x相应地扩展为x = x g < （其中x g是地滚动贡献，并且Δx= x sig + x ran）;其中x sig sub>是反射信号分量，而x ran是随机噪声分量）。 Δ分量包含在成本函数J的分母中，以提供由反射信号偏置的滤波器系数的最优解，并去除随机噪声。
