Two Key Questions
Can we efficiently incorporate the Sedimentology and Stratigraphy in a 3D Static Model, considering the complexity of Talara
What is the best way to integrate the diagenetic complexity in these models? Objectives
Characterize the facies associations to interpret the depositional model;
Create a stratigraphic framework for propagation of petrophysical properties;
Assess the diagenetic impact in determining the reservoir quality distribution;
Expected Results: optimization, risk and uncertainty reduction in EOR projects. Conclusion
The integration of sedimentology and stratigraphy, combined with geostatistical tools, provided a better understanding of geometrical relationships and connectivity potential of the reservoirs within each stratigraphic unit.
