Product Sheet Time-Lapse 3D VSP Processing
Accurate monitoring of reservoir changes caused by injection and production.
For more than 30 years, we have been refining our workflows and technology to deliver high-quality, repeatable time-lapse seismic data in a variety of geologic settings. We have experience with all acquisition types, including marine streamer, ocean bottom, land, and permanent monitoring seismic data. With dedicated QC procedures, 4D processing algorithms, and flexible matching technology, we work with you to enable rapid and routine delivery of monitor surveys that are optimized to meet your objectives.

Efficient and accurate time-lapse seismic processing requires a clearly defined approach to identify and mitigate the acquisition-related variability that would otherwise obscure the reservoir changes. Our workflows incorporate algorithms built specifically for time-lapse processing, removing the effects of differing acquisition systems for optimal repeatability. Using mostly deterministic algorithms, we minimize the use of statistical matching processes, particularly where preservation of geomechanical effects are paramount. If deterministic algorithms cannot be used, simultaneous processing of the baseline and monitor surveys is often the key to ensuring stability and consistency.
Our workflows are designed, as possible, to ease application to subsequent monitor surveys. In many cases, a new monitor can be processed independently of the preceding surveys, further reducing processing turnaround time. Not only are your costs minimized, but the early availability of your data ensures that the monitor survey provides returns on your investment as quickly as possible.
