A RESERVOIR MODEL FOR THE MAIN PLIOCENE RESERVOIRS OF THE BAHAR FIELDIN THE CASPIAN-SEA, AZERBAIJAN

In this paper the results of a reservoir evaluation study of the Bahar Field, one of the most important oil and gas fields in the Azerbaijan ian sector of the Caspian Sea are presented. The study has concentrate d on the most important reservoir sections, Balakhany X and Pereriv Su ite, encompassing (i) sedimentological and stratigraphic interpretatio n, (ii) petrophysical analysis, (iii) structural interpretation, (iv) assessment of hydrocarbon distribution, (si) geochemical characterizat ion of the hydrocarbons, (vi) assessment of reservoir compartmentaliza tion, (vii) establishment of static and dynamic reservoir models in di gital format, as a basis for calculating in-place resources and assess ing the potential for improved oil recovery. The study has provided ne w and detailed insight into the reservoir architecture and properties of the Bahar Field. In a broader context this detailed information and data analysis is believed to provide an improved basis for evaluating other tested and untested structures in this prolific hydrocarbon pro vince.
