• Core studies of wells in offshore and nonshore areas. This work included facies characterization, one dimensional sequence stratigraphic analyis and environmental interpretation for ArabA,B,C cycles,Hanifa, Manifa, Mauddud, and Mishrif Reservoirs.

• An sedimentologic/diagenetic analysis of Hith and Arab anhdrite from off shore wells. The main objectives focus on establishing the depositional relationship between carbonate and evaporite, the high resolution sequence stratigraphic framework for the evporite-carbonate section, develop a depositional-diagenetic model to explain the development of the evaporite section and to identify potential stratigraphic traps.
