We developed an independent probabilistic reserves assessment for this field in the Caspian Sea in accordance with PRMS standards. This field is a very large post-salt clastic structure with multiple and varying production horizons. We developed a fully integrated geological and reservoir simulation model for the field. The work included full assessment and interpretation of a 3D seismic data set, development of a static geological model and a dynamic reservoir model. We Carried out modelling to determine optimum configuration through consideration of water injection support and gas re-injection alternatives. We also carried out conceptual field development planning to determine the associated surface production scheme.
The special features considered included correct modelling of multiple production layers and sand qualities. We prepared a reserves certification statement in accordance with PRMS standards. We also prepared a reserves statement in accordance with regulations set down by Kazakhstan’s State Reserves Committee.
