Abstract

A new automated and integrated, vessel, source, and receiver control system has been developed to improve the accuracy and repeatability of 4D surveys. The new control system replaces operator intervention with automated updates to vessel, source, and streamer steering devices from positioning information from all in-sea equipment. This has lead to a step change in the accuracy of source repeatability (2.5-m repeat accuracy for 95% of shotpoints), and has also improved the ability to repeat receiver positions.
