Sequence Stratigraphy of the Arab C Carbonates in Khursaniyah Field, Eastern Saudi Arabia

The reservoir-bearing Arab-C carbonate in Khursaniyah field (150 ft thick) is an overall fining-upward composite sequence that can be subdivided into six high-frequency sequences. Each of these high-frequency sequences can be further subdivided into multiple fining-upward small-scale cycles.;A high resolution sequence stratigraphic framework for the Arab-C carbonates and the underlying and overlying evaporites is built and the associated depositional models within the sequence stratigraphic framework of Khursaniyah field are also generated.;This work aims to enhance the understanding of both the sedimentological and depositional models of the Arab-C reservoir. Also, to understand the stacking pattern of the carbonates / evaporite succession within a high resolution sequence stratigraphic framework. This should make it possible to better resolve the scale of correlation and to map the reservoir facies within this framework; hence, define the geologic factors that control the reservoir quality (sedimentological and sequence stratigraphy). This could provide insight into the depositional---stratigraphic style of the Late Jurassic near the equator, and thus offer additional insights on possible global climate and tectonics controls for this time period. Moreover, provide a predictive conceptual model of reservoir development grounded in the fundamentals of process sequence stratigraphy and sedimentology.
