Recent studies by the principal investigator show that the midpoint scattering in 2D multichannel seismic studies can be used to advantage by processing that takes into account the 3D character of the data and of the geology. The final products are a much improved stack, determinations of structural dips at right angles to the survey line, and a significantly improved velocity model. Further improvements in the developed automatic techniques for extracting local crossdip moveout and producing optimum crossdip stacks will be pursued. These techniques will be made available to the community.

主要调查员最近的研究表明，二维多道地震研究中的中点散射可以通过考虑到数据和地质的三维特征的处理来加以利用。 最后的成果是一个大大改进的叠加、与测线成直角的构造倾角的确定以及一个显著改进的速度模型。 将进一步改进所开发的自动技术，以提取局部横倾时差和制作最佳横倾叠加。 这些技术将提供给社区。
