Abstract

This study presents a unique approach of performing interval velocity analysis using multi-parameter CIGs for the 2D case. During the analysis, summation-free CIGs are generated and are analyzed as constant depth slices at every image location. When formation tops information is available, an efficient procedure for updating the velocity can be utilized. A specific pattern which can be used to identify correct and wrong velocity within each of the depth slices is used as the core of the analysis. The ability to analyze the structural parameters of each image point improves the accuracy of the velocity and at the same time provides valuable structural information at the analysis location. The procedure and the potential accuracy of proposed method are demonstrated for the 2D case.
