Leveraging Legacy Data

In recent years, there have been many rapid developments in subsurface imaging, meaning that even data sets that are only two or three years old can benefit from reprocessing. Reprocessing older data, either on its own or in combination with new data, is both practical and cost-effective as new acquisition can be expensive and time-consuming, especially in areas where there are seasonal constraints due to climate, fishing or breeding seasons. The Cornerstone Evolution project in the Central North Sea demonstrates the value achieved by reprocessing a large number of older surveys in conjunction with newer acquisition.
