9526786 Frazer This research is to develop the theory for determining the speeds of P- and SV- waves in a solid containing plane-parallel fractures. The fracture separation is random in accordance with a specified probability density function, and the fracture compliances are also random in accordance with another specified probability density function. Prior results for SH, now in press, suggest that the project is feasible. Three new methods were developed for SH, and they all agree with each other; the goal is to generalize these three methods to the PSV problem. The results have application to the inversion for seismic velocity structure in plane-parallel fractured media, a situation that is widely applicable to the crust of the earth, particularly in the context of secondary and tertiary recovery of oil and gas, and in geothermal operations.

小行星9526786弗雷泽 本研究旨在发展含平面平行裂缝固体中P波和SV波速度的确定理论。 裂缝间距是随机的，根据一个指定的概率密度函数，和断裂柔度也是随机的，根据另一个指定的概率密度函数。 SH的先前结果（现已出版）表明该项目是可行的。 三个新的方法开发的SH，他们都同意对方的目标是推广这三种方法的PSV问题。 结果应用于地震速度结构的反演，在平面平行裂缝介质，这种情况是广泛适用于地壳的地球，特别是在石油和天然气的二次和三次回收的背景下，并在地热作业。
