Innovations in Time - Experiences in 4D Time-Lapse

Time-lapse or 4D seismic technology has existed for quite some time; the first 4D seismic survey was acquired in 1981 onshore Canada. Today, 16% of Q-Marine single-sensor seismic surveys are related to the monitoring of reservoir production. One reason for the growth of seismic reservoir monitoring programmes is that, in the last five years, the industry has responded to 4D seismic imaging challenges through a number of significant enhancements in repeatability. This, combined with innovations in 4D analysis and interpretation, has caused time-lapse seismic technology to become an integral part of the business process of many oil companies.
