Using seismic spectral blueing for enhancing seismic resolution: a case study from a mature field in a rift basin, southwestern Gulf of Suez, Egypt
Authors Ibrahim Attia, Hatem Ewida and Said A. AlyAbstractSeismic 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.

A new higher-resolution multi-trace seismic discontinuity attribute based on a Dynamic Time Warping algorithm
Authors I.I. Priezzhev, D.A. Danko, U. Strecker and P.C.H. VeekenAbstractA new machine-learning approach based on a Dynamic Time Warping (DTW) algorithm is introduced to detect faults and fractures in 3D seismic data from an unconventional resource play in Eastern Cis- Caucasia (Russia). This novel approach allows for better edge detection in seismic amplitude volumes because it employs a detailed comparison of two neighbouring traces to detect discontinuity via a minimal horizontal distance. For benchmarking purposes the proposed DTW method is compared to a widely used multi-trace attribute (Variance). Subsequently, both calculated attribute cubes serve as an input for ANT-Tracking to delineate fault strike and fracture corridor trends. A comparison of results shows that better resolution and more complete fault images are obtained when the DTW method is applied.
