In the 20th century, modern 3D seismic technology was instrumental in reducing discovery costs. Today time-lapse or 4D seismic is enabling oil companies to optimize production and increase recovery through monitoring fluid movements throughout the reservoir. This ability to accurately monitor fluid movements is driven by improvements in seismic signal fidelity and repeatability from the application of
Q-Technology, together with
Well-Driven Seismic data integration.
In geomechanically active reservoirs such as compaction drive reservoirs, we can detect traveltime changes not just in the reservoir, but also in the overburden. In these reservoirs, production causes subsurface deformations and changes in seismic velocity. These deformations and velocity changes in the overburden can be monitored using time-lapse seismic data.
