4D Seismic for Late Life Field Development — Example from Balder and Ringhorne Fields

Throughout the production life of the Balder & Ringhorne fields, 4D seismic has proven to be a valuable tool and been used extensively: In 2006, 2009 and 2012, monitor surveys were acquired to support the Ringhorne Phase II and Balder Phase III drilling campaigns in target maturation and optimization. In 2017, Vår Energi became operator of Balder and Ringhorne and initiated a major redevelopment plan to maximize the area potential by extensive infill drilling, the provision of additional processing capacity and field-life extension. In 2018, a new monitor survey was acquired to support this new development phase. Results from fast track processing show high repeatability and insightful early observations.
