Abstract
We present a time-lapse 4D seismic case history from the Hess operated Danish South Arne field. Results from 4D monitor surveys are time critical if they are to have maximum impact on field management issues. Definition of precise survey objectives by the integrated reservoir management team enables the design and rapid execution of a 4D seismic monitor program. Such data sets can deliver timely information critical to impact current work-over programs and new drilling opportunities, plus give additional information for reservoir characterization. Key to the project turnaround is the use of calibrated and automated acquisition technologies, which provide an accurate repeat of source and receiver positions, and enable the use of deterministic seismic data processing flows. We demonstrate how such a towed streamer monitor survey was acquired with delivery of time lapse data volumes within 2.5 weeks of last shot, and describe the impact this data has had upon the ongoing reservoir management and characterization of the South Arne field.
