Abstract

Abstract

Seismic resolution plays a key role in oil exploration and development. An increase of the seismic frequency content can improve resolution and imaging quality significantly, revealing the presence of minor structures that may highlight geologic features of interest. This can be particularly important during the production phase of mature oil fields with thin producing reservoir(s).

The presented workflow has resulted in a more detailed seismic interpretation of an oil field in the Gulf of Suez basin, Egypt. Applying seismic spectral blueing solved the resolution limitation for interpreting minor faults, and allowed better well positioning and improved reserve estimation. In this workflow, the seismic attributes are interpreted and integrated with the geological datasets available for improved structural modelling.
