Abstract: The present disclosure provides a method for modeling and analyzing the impact of different seismic surveying and imaging techniques on a subterranean formation by creating a black hole boundary condition around a particular region in the formation where at least one of the physical characteristics is unclear and may distort the seismic modeling results. The black hole boundary conditions will eliminate any energy wave that enters, exit or reflect off the region so as to avoid any image distortion caused by this region. The resulted image data is compared with the image data obtained without using the black hole boundary conditions to determine the impact of this region, and proper correction can be made to more precisely and accurately model the formation
Abstract translation: 本公开提供了一种用于通过在地层中的特定区域周围产生黑洞边界条件来建模和分析不同的地震测量和成像技术对地下地层的影响的方法，其中至少一个物理特性不清楚并且可能会扭曲 地震建模结果。 黑洞边界条件将消除进入，退出或反射出区域的任何能量波，以避免由该区域引起的任何图像失真。 将所得到的图像数据与不使用黑洞边界条件获得的图像数据进行比较，以确定该区域的影响，并且可以进行适当的校正以更准确和准确地模拟形成

Abstract: Imperfect separation at the higher frequencies has been observed and was eventually was tracked down to the poor GFE signal that is normally used in the inversion. The invention thus uses a “derived GFE” for each source, obtained by comparing the shot records and remove the differences, instead of the prior estimated GFE signal put out by the controller, thus accurately maximizing the separation of the data.
Abstract translation: 已经观察到在较高频率下的不完全分离，并且最终被追踪到通常用于反演的差的GFE信号。 因此，本发明对于每个源使用“派生的GFE”，通过比较拍摄记录和消除差异而获得，而不是由控制器输出的先前估计的GFE信号，从而精确地最大化数据的分离。

Abstract: A multi-stage inversion method for deblending seismic data includes: a) acquiring blended seismic data from a plurality of seismic sources; b) constructing an optimization model that includes the acquired blended seismic data and unblended seismic data; c) performing sparse inversion, via a computer processor, on the optimization model; d) estimating high-amplitude coherent energy from result of the performing sparse inversion in c); e) re-blending the estimated high-amplitude coherent energy; and f) computing blended data with an attenuated direct arrival energy.
