Technical Abstract

PS depth imaging to detect clastic reservoirs -- Vietnam's first 3D-4C OBC survey in the Cuu Long Basin

Back to Technical Content
In this paper, we focus on how to use PS imaging to help detecting the reservoir in the clastic layers. PS data allows for imaging of these reservoir units that have poor P-wave but high PS-wave reflectivity and also for lithological discrimination via extracted Vp/Vs values. To achieve such information, there are some key processing steps necessary to resolve. These include shear wave inversion, shear wave splitting analyses, demultiple, and finally, PP-PS joint inversion. Also, the initial results of PP-PS joint AVO inversion shows clear indications of the alternative target zones, and conform to the interpretations of these pay zones.
