To guide cost effective designs of future ocean bottom seismic (OBS) for 3D, 4D or permanent sensor time-lapse, surveys over the Azeri, Chirag and Gunashli reservoirs, a multi-faceted study was conducted evaluating both real OBC seismic data from Azeri and synthetic data from numerical modeling. This study evaluated sensor density requirements to properly acquire the PZ component of the wave field, as this component provides the best reflector S/N and, depending on rock physics, is sensitive to production-related fluid changes in the reservoir. Critical spatial sampling and acquisition parameters were established through a series of comparison tests including |
