Carbonate Reservoir Characterization: Part 18
1. How exactly the origin and deposition of carbonate sediments remain controlled by tectonism, climate, eustatic and sedimentation changes, which essentially condition the architecture of the carbonate deposits, the discontinuities and the resulting distribution of petro-physical properties?
2. How exactly the chemical reactivity of carbonate rocks dictate the resulting reservoir heterogeneity?
3. Why do we end up with a relatively lower producing GOR in fractured carbonate reservoirs?
When could we expect a relatively high vertical communication in fractured carbonate reservoirs, which would probably cause the liberated gas to get segregated towards the top of the reservoir?
4. What are the favorable circumstances in a carbonate reservoir that would cause a relatively larger supply of fluids into high permeable fracture from low permeable rock-matrix, resulting from gravity and imbibition (combined with fluid expansion), segregation and advection?
Will it always lead to a relatively lower rate of pressure decline (per barrel of oil produced)?
