Abstract: A method, including: determining, with a computer, point spread functions for a plurality of parameter locations by performing at least a portion of a first iteration of an iterative full wavefield inversion process; determining at least one property for each of the point spread functions; and evaluating a candidate survey design based on the at least one property for each of the point spread functions.

Abstract: In the present inventive method, individual traces of seismic data are migrated (41) without any assembling of different midpoints or any summing of different offsets, so that post-migration processing or analysis, e.g. trace alignment, may be applied to the individual migrated traces (42) to compensate for any deficiencies among them, before stack and assembly. Thus, the present invention fully separates the steps of migration (41), assembly (43), and stacking (44), which are combined together in traditional migration. Thus, imaging deficiencies can be measured and addressed in the image space before they are obscured by summation. Afterward, summation can proceed to construct the improved final image (45).

Abstract translation: 在本发明的方法中，地震数据的各个轨迹被迁移（41），而不需要任何组合不同的中点或任何不同偏移的相加，以便移植后处理或分析。 迹线对准可以应用于单个迁移迹线（42），以在堆叠和组装之前补偿它们之间的任何缺陷。 因此，本发明完全分离了在传统迁移中组合在一起的迁移步骤（41），组装（43）和堆叠（44）。 因此，成像缺陷可以在图像空间被测量和掩蔽之前被求和。 之后，可以进行总结来构建改进的最终图像（45）。
