Seismic technology has significantly progressed since the discovery of most of Oman’s oilfields in the 1980s and 1990s, with the emergence of 3D Wide Azimuth (WAZ) since ~2010 revealing new subsurface images. Petroleum Development Oman (PDO) has developed advanced processing techniques to address seismic imaging issues and innovatively created the Megacell technique, which merges various 3D seismic volumes. This overcomes disunited seismic data challenges and enables comprehensive regional analysis in the Fahud Salt Basin (FSB). This integration offers unprecedented seismic insights, yet its full potential in researching the tectonostratigraphic evolution of the FSB remains underutilized. This study builds on previous work, using seismic imaging and structural geology techniques to piece together the evolution of the basin. Ten regional stratigraphic horizons and numerous faults were mapped from the Late Neoproterozoic to the present-day using 3D seismic and deep wells data across an area of 32,418 km². The focus was on the main bounding features that significantly exert structural controls in the evolution of the basin. The study underscores the significant impact of Late Neoproterozoic structures, variations in Ara salt thickness and geometry on the development of main structural elements, including faults and folds, in key areas like the Fahud, Natih, and Yibal fields and the main thrust front of Oman Mountains. Utilizing the advanced WAZ 3D seismic semblance attribute and in-depth geological field studies and maps, this research provides a novel understanding and mapping of the Maradi Fault Zone (MFZ). The Yibal-Khuff structural formation was developed in the region with the thickest Ara salt, which was distanced from the main thrust front, allowing the salt to function as a ductile core, causing buckling in the overlaying rocks at a more regional level. Moreover, the pre-existing Neoproterozoic structural grain influenced fault development and growth in the overlying strata. Detailed geological map analysis in the Fahud and Natih areas was integrated to link the surface geology to subsurface seismic data. This helped extend the interpretations, guided by a comprehensive understanding of Oman's regional tectonics. Structural reconstruction was applied to a 222 km regional line traversing the Hawasina Thrust Sheets (main thrust front), MFZ, Natih, and Fahud fields, and the southern extent of the Yibal Field. It is instrumental in synthesizing regional observations and charting the basin's evolution from the Ara salt deposition to the present. This research aids in constructing an updated burial history for the basin, offering novel insights for field development and exploration strategies. The method, starting from a broad regional perspective and refining to detailed fields and fault zones, enabled a redefinition and testing of regional observations.
