Maximising the Value of Seismic Data for Continued Mature Field Development in the East Shetland Basin

Abstract

Careful reprocessing of seven vintage surveys covering oil fields in the East Shetland Basin was undertaken, eventually leading to a high quality preSDM deliverable. Attention to preserving all available long-offset information was especially beneficial in improving velocity resolution. In the case of this dataset, structure and stratigraphy are more clearly imaged and the fields can be seen in their broader geologic context. The data have already been used to guide development and appraisal well drilling as well as confirming and updating existing geological models.
