Multidisciplinary Approach for Petroleum Play Reconstruction of Dislocated Heterogeneous Carbonate Reservoirs Within the World's Most Ancient Riphean Formation

This paper concerns the variety of geological uncertainties of unique ancient carbonate (fractured crystalline dolomite) reservoir. 1st phase of the entire project is nowadays successfully prepared to development, but it took more than 30 years, since the relevant technologies were obtained. 2nd phase of this project being poorly studied includes up to 30% of resources and is located 50 km to the East. Key challenge is connected to very complicated reservoir geometry and internal structure, which is characterized by uncertain stratigraphic and reservoir boundaries and blocks saturation.

The main objectives of this investigation are to design, to perform and to analyze research program based on historical wells core and fluid samples and, as a result, to reconstruct petroleum play for this Eastern part of the field in order to organize most effective exploration activities.
