Abstract

In this case study we explore the use of both PP elastic impedance (EI) and PS elastic impedance (PSEI) inversion on ocean bottom cable (OBC) data from the West Cameron area in the Gulf of Mexico (GOM), where PS data has higher S/N ratio. We show the advantages of PS data and describe a workflow for joint PP and PS inversion to extract elastic properties from seismic data. A comparison between separate PP and PS data and joint PP-PS data in PP time shows that in this case PS data critically improve subsurface characterization.
