Abstract: Refracted energy travel time can help to derive anisotropic parameters in a target layer. These anisotropic parameters allow us to both explore for new reservoirs and to understand stress and fracturing in existing reservoirs. This information can be used to i) detect oil reservoirs, ii) spot naturally fractured, hence high production zones, iii) detect dominant natural stress directions, iv) better place horizontal wells to optimize production, v) monitoring man made fractures or induced directional stress changes. The method is demonstrated using synthetic and real data.

Abstract translation: 折射能量行进时间可有助于在目标层中导出各向异性参数。 这些各向异性参数使我们能够探索新的水库，并了解现有水库的应力和压裂。 这些信息可用于i）检测油藏，ii）点自然裂缝，因此高生产区，iii）检测主要的自然应力方向，iv）更好地放置水平井以优化生产，v）监测人造骨折或诱导定向 压力变化。 该方法使用合成和实际数据进行演示。
