Multi-Component Seismic Data Processing of a 3D 4C OBC Dataset for Lithological Identification Through PP/PS Joint Inversion: A Case History

In this case history we present the advantages and improvements in lithological discrimination and identification by implementing a robust seismic data processing workflow of vertical component (PP) and converted wave (PS), for a 3D 4C dual sensor OBC dataset.

The image quality of the P-wave using dual sensor data will be demonstrated by the robustness of the applied processing sequence and quality control tools. We will demonstrate in details the converted wave measured from the horizontal component processing, where the interpreters geological knowledge, incorporated into the integration of processing applications, plays a major role in the success of the final PS data results.

Integrating PP / PS images and introducing PP, PS processed data in one solution should enhance the interpretation resolution at the target interval. Improved Vp/Vs for prominent markers and more accurate AI through PP/PS joint inversion is continuously evaluated throughout the processing workflow. Eventually, our main objective is the utilization of PP/PS processed data in joint inversion to produce accurate lithology discrimination maps.
