A new Previous HitsequenceNext Hit-stratigraphic framework is proposed for the Burgan and Mauddud formations (Albian) of Kuwait, based on the integration of core, Previous HitwellNext Hit-Previous HitlogNext Hit, and biostratigraphic data, as Previous HitwellNext Hit as seismic interpretation from giant oil fields of Kuwait.

The Lower Cretaceous Burgan and Mauddud formations together form two third-order composite sequences, the older of which constitutes the lowstand, transgressive, and highstand Previous HitsequenceNext Hit sets of the Burgan Formation. This third-order composite Previous HitsequenceNext Hit is subdivided into fifteen, high-frequency, depositional sequences, which are characterized by tidal-influenced, marginal-marine deposits in northeast Kuwait that grade into fluvial-dominated, continental deposits to the southwest. The second, younger third-order composite Previous HitsequenceNext Hit consists of the lowstand Previous HitsequenceNext Hit set of the uppermost Burgan Formation and the transgressive and highstand Previous HitsequenceNext Hit sets of the overlying Mauddud Formation. This composite Previous HitsequenceNext Hit is sand-prone and mud-prone in southern and southwestern Kuwait and is carbonate-prone in northern and northeastern Kuwait.

The Mauddud transgressive and highstand Previous HitsequenceNext Hit sets are subdivided into eight, high-frequency, depositional sequences. The lower Mauddud transgressive Previous HitsequenceNext Hit set displays a lateral change in lithology from limestone in northern Kuwait to siliciclastic deposits in southern and southwestern Kuwait. The traditional lithostratigraphic Burgan-Mauddud contact is time-transgressive. The upper Mauddud highstand Previous HitsequenceNext Hit set is carbonate-prone and thins south- and southwestward due to depositional thinning. Significant post-depositional erosion occurs at the contact with the overlying Cenomanian Wara Shale.

The proposed Previous HitsequenceNext Hit-stratigraphic framework and the incorporation of a depositional facies scheme tied to the Previous HitsequenceNext Hit-stratigraphic architecture allow for an improved prediction of reservoir and seal facies distribution as Previous HitwellNext Hit as reservoir quality away from Previous HitwellTop control.
