“…1B-D) (Yildiz 2022; Azim et al 2019;Alsharhan and Nairn 1986;Sharland et al 2001). Kuwait's stratigraphic section comprises three petroleum systems: The Cretaceous petroleum system, which is the primary system that contributes to production (Behbehani et al 2019;Al-khamiss et al 2009), and the Jurassic petroleum system, which is separated from the above Cretaceous system by the thick evaporates of Gotnia and Hith formations of about 2300 ft thickness (Aladwani 2022a;Al-Wazzan et al 2022;Fox and Ahlbrandt 2002), and the Paleozoic petroleum system. However, there is insufficient information about the Paleozoic system because its high depth is not penetrated in the boreholes except in very few wells.…”

We used wireline logs, seismic, core data, fluid analysis, and geochemical data to investigate the total petroleum system in the Cretaceous period. Also, we used thin sections and fluid analysis throughout the investigation. Python’s 1-D backstripping technique was used to determine the abrupt changes in subsidence rates and their effect on the reservoir’s quality. The results defined that the potential reservoirs include, from top to bottom, Mauddud, Upper Burgan, Lower Zubair, and Ratawi Limestone. The reservoir facies reflect different environments between the carbonate ramp (Mauddud, Ratawi Limestone, and Minagish reservoirs), delta plain (Zubair reservoir), and margin shelf (Burgan reservoir), and its quality is graded from Mauddud to Ratawi Limestone from top to bottom. The field lies up-dip under Kuwait Bay and represents the continuation of super-giant Greater Burgan Field. It filled with the spilled oil from the down-dip Raudhatain and Sabriyah fields through a structural saddle. Two major tectonic events subsided the deposited sediments by 0.25 mm/year, besides three minor events; however, these events did not affect all Cretaceous reservoirs but only according to their deposition times. Furthermore, according to burial history, thermal maturity, and reservoirs’ fluid geochemical analysis, the Sulaiy (Makhoul) and Minagish formations are likely the primary sources for all Cretaceous reservoirs.
