This Small Business Innovation Research (SBIR) Phase I project proposes to investigate the feasibility of a key technology designed to enhance seismic resolution and imaging of deep-water complex geologic structures by using variable azimuth wave-equation migration (VAWEM). VAWEM will provide much greater resolution and accuracy than what can be accomplished today for towed marine streamer data, and at significantly less computational cost.This advanced imaging methodology will improve success rate and cost effectiveness for new field discoveries and increase recovery efficiency for the development of existing fields. This technology does not exist in the industry, it is a fundamental revolutionary advance, and is a necessary building block in any seismic processing system that images 3-D prestack data using wave-equation methods for imaging deep water, under-salt complex geological structures which are the focus of modern oil- and-gas exploration.

本小企业创新研究（SBIR）第一期项目提出了一个关键技术的可行性研究，旨在提高地震分辨率和成像的深水复杂地质结构，通过使用可变方位波动方程偏移（VAWEM）。 VAWEM将提供比目前拖曳海洋拖缆数据更高的分辨率和精度，而且计算成本显著降低。这种先进的成像方法将提高新油田发现的成功率和成本效益，并提高现有油田开发的采收率。该技术在工业中不存在，它是一个根本性的革命性进步，并且是任何地震处理系统中的必要构件，该地震处理系统使用波动方程方法对三维叠前数据进行成像，以成像深水、盐下复杂地质结构，这些是现代石油和天然气勘探的焦点。
