Abstract

Abstract

Converted PS-wave data are recorded mostly on horizontal receiver components while acquiring offshore ocean bottom cable (OBC) or node (OBN) data and onshore with three-component (3C) receivers. Even so, over the years, the industry has not been utilising this data to its full potential. With modern acquisition and advanced processing there are multiple applications where PS-waves make a strong value statement and can be utilised more extensively to improve exploration and production success. In this paper we show a collection of recent industry applications of this technology to multiple case studies demonstrating the value and improvements in areas such as elastic Full Waveform Inversion (FWI), quantitative direct hydrocarbon indications, subsalt reservoir characterisation, imaging under complex overburden, such as shallow gas, enhanced time-lapse seismic analysis and estimation of pore pressure in the overburden and reservoir. We also discuss the status of PS data processing and factors impacting PS data quality.
