Beyond the Pereriv - Integrated Reservoir Characterisation of Balakhany Reservoirs in the ACG Field, South Caspian Basin

Oil production from the Azeri-Chirag-Gunashli (ACG) Field will reach 1 million bopd upon completion of ACG Phase 3, with the majority of production coming from the high net-to-gross Pereriv B and D reservoirs. Significant hydrocarbon resources remain in the lower net-to-gross and stratigraphically more complex Balakhany Reservoirs which overlie the Pereriv. Developing these resources requires a much more detailed understanding of the reservoir geology than has previously existed. An integrated approach to reservoir characterisation has led to new high resolution stratigraphic models being developed and used as the basis for 3D geological modelling and subsequent reservoir simulation modelling.
