Depth Trend and the Characteristics of PS AVO

摘要

Gonzalez et al. (2003) & Xu et al. (2005) showed the application of PS Elastic impedance (PSEI) for lithology and fluid prediction. To understand the effectiveness of this approach in relation to the target depth, it is necessary to analyze the typical characteristics of PS AVO in a compaction trend framework. In this paper, we will review the typical depth trend of sand and shale properties in a sedimentary basin, and discuss the characteristics of PS AVO in several unique depth zones.
