The structural mechanisms and stratigraphic features of the earth strongly control the hydrocarbon potential of any oil field. In this study, we selected the Sufr El Dara offshore oil field, Southern Gulf of Suez, Egypt, as the area of interest. This field has a complex structure and stratigraphic features owing to being located in the Morgan accommodation zone. The lateral and vertical facies are substantially different. Conventional techniques applied to open-hole logs and seismic data have failed to produce a reliable model of the study area. To minimise the risk factors and select the best location, we developed a workflow to integrate different techniques to describe the complexity of the study area. Our interpretation is based on detailed reservoir correlations. As the main tool, we used comprehensive interpretation of the well data (e.g., E-logs and dipmeters) to define the pattern of the faults and the extent of the reservoir. In addition, we incorporated seismic techniques (e.g., spectral decomposition and unsupervised vector quantiser for waveform classification), first used in the Gulf of Suez region, which considerably impacted the mapping of the structure and stratigraphic features at the reservoir level. We used multiple targets for interpretation, although our focus was constructing the main structural model of the study area at the Kareem level. We found that the proposed geological model is a powerful predictive tool for locating structural closures and reservoirs. The model will assist in the exploration and development not only of conventional structure plays (clysmic trends) but also of more unconventional stratigraphic plays focusing on Kareem fans, which were produced by the combination of both stratigraphic and structural traps in the study area. • Gulf of Suez rift basin. • Offshore Gulf of Suez. • Spectral decomposition in rift basin. • Multi-seismic attribute. • Waveform classification.
