Seismic support service for life-of-field monitoring for Shell, offshore Brazil

The seismic sensor cable array was installed on the seafloor in 2013 with the intent of monitoring the life of the BC-10 field with successive short-duration seismic source programs. This design streamlines the process of higher generation acquisition by removing the need for receiver deployment and recovery time and guaranteeing consistency of receiver positions by leaving the cables in their original location on the seabed. The seismic data collected is used to detect, monitor, and plan for changes in the subsurface as the field is developed.

RPS has been involved in the BC-10 Life of Field Project since 2011 starting first with the factory acceptance testing of the OYO Geospace’s GeoRes SubSea seismic array system in Houston. RPS has since worked for Shell on this project supporting all of the infield seismic surveys for the BC-10, starting with the original 2013 baseline survey. Since that time, RPS has worked on five monitor surveys with the January 2020 survey being the most current.

To ensure consistency and knowledge retention through these seismic surveys, RPS has used the same specialist since the inception of the work and deployed a seismic processing workstation with processing flows prepared by RPS.

The seismic recording room and QC processing centre for this project are located onboard the massive floating production, storage and offloading (FPSO) vessel, Espírito Santo. RPSs knowledge of these systems and data and the retention of knowledge over time has helped deliver consistent success for Shell, year over year.

RPS’ highly talented seismic acquisition and QC processing team ensure consistency and knowledge retention through these seismic surveys for Shell offshore Brazil.
