Abstract

Summary

4D seismic is a key technology to de-risk all new wells drilled on the Forties Field. Identifying remaining oil targets requires new acquisition to capture recent production effects, and repeated reprocessing of existing 4D vintages to capitalise on developments in processing algorithms and methodologies. As an example of these developments, the challenge of acquisition differences with a 1988 baseline survey has been addressed with optimal trace matching. The benefits of reprocessing are demonstrated through improvements to 4D noise metrics and interpretability of 4D seismic sections.
