“…The primary goal of utilizing seismic interpretation is to provide accurate and comprehensive evidence of the structural and stratigraphic aspects of the seismic prospect (Khan, Farid, et al, 2021; Khan, Zhang, et al, 2021; Naseer et al, 2022). The conventional interpretation approach was followed to ensure an accurate structural analysis.…”

“…The conventional interpretation approach was followed to ensure an accurate structural analysis. Reflections are caused by variations in acoustic impedance through subsurface rocks that have different physical properties (Khan, Farid, et al, 2021; Khan, Zhang, et al, 2021; Naseer et al, 2022). Figure 3 depicts a geological column that represents the entire lithology and thickness of the Miocene and Pre‐Miocene sediments.…”

“…More oil gains and successful development plans are the result of excellent regional structural understanding (Khan, Farid, et al, 2021; Khan, Zhang, et al, 2021; Radwan, 2022a). The newly developed structural model is the result of the integration of previous work and the most recent data from various disciplines.…”

“…Current energy industry research is focused on improving subsurface resource exploitation through improved resource assessment and efficient production, identification, and obtaining a precise structural model based on subsurface geological information is critical (Gao, 2011; Holden et al, 2003; Jolley et al, 2007; Radwan, 2022a). To create a structural model of a subsurface hydrocarbon reservoir, many data sets must be acquired, including seismic data and well logs, followed by well correlation and data interpretation (Ali et al, 2022; Hart, 1999; Hennings et al, 2000; Khan, Farid, et al, 2021; Lohr et al, 2008). Advancements in three‐dimensional (3D) modelling have allowed for better imaging of subsurface reservoirs in the petroleum industry (Gao, 2011; Radwan, 2022a).…”

Three‐dimensional structural modelling of structurally complex hydrocarbon reservoir in October Oil Field, Gulf of Suez, Egypt

The October Oil Field is structurally complex due to its presence in the structurally complex system of the Gulf of Suez Rift Basin area, with the last updated structural model developed in 2012. Although the 2012 model defined the general structural framework and reservoir architecture, many challenges arose during the field development. The current study is focusing on the structural elements affecting this giant field to update the field structural model using the newly processed 3D seismic survey, the acquired data from newly drilled wells, and the associated different logging techniques. Several geological structure contour maps and cross‐sections were generated to help in delineating and understanding the reservoir's extension. Based on the detailed correlation study, we were able to detect the faults that affected the structure of the October Field in detail, define their throw amounts and directions, and identify the missed sections across the studied area. This study introduces a comparison between the old and updated model scenarios to show the differences and their effect on the field development plan and recommendations. The updated model shows differences between the 2012 model and the current study's modified model in the number, extension, and location of faults: the old model has 17 faults, while the modified model has 13 faults. The main clysmic fault “F1” has a significant impact on the entire field because it affects all studied wells. Furthermore, the F3 and F4 faults have a significant impact due to their ability to create and add compartmentalization within the area of study. This study revealed that the updated detailed 3D structural model can support the development plans for the Nubia reservoir and motivate drilling, workover, and dynamic operations to assign the development opportunities in the proper location. Based on the developed model, there are at least three opportunities in the attic areas of the study that could increase oil production and oil reserves for the field while avoiding any more failures.
