CO2 Sequestration [Reservoir Hydrodynamics 02]
1. Whether CO2 trapping follows a simple logic that CO2 and brine always migrate from an area with high potential energy to an area with low potential energy?
2. Whether CO2 gets trapped with low potential energy to form CO2 storage?
3. By referring to the characteristics and variations of the field of CO2 potential energy, can we forecast the direction of CO2 migration and the favorable areas for trapping in a studied area @ different periods?
4. Whether, CO2 trap is a place, where, the dynamic force of CO2 migration and the resisting force reach a balance to cause CO2 to get trapped?
5. Whether the migration and trapping of CO2 require the concept of fluid potential, which is essentially a reflection of the joint action of the hydrodynamic force, fluid pressure, buoyancy and capillary force on the movement of CO2-brine fluids?
6. Although, both Hubbert and England
(a) believed that a fluid dynamic force could influence the scale of a fluid potential, which includes buoyancy, stratigraphic pressure, capillary pressure and hydrodynamic forces;
(b) asserted that the flow of a fluid gives rise to kinetic energy; With CO2 being compressible, can we calculate CO2 potential in the fluid potential field using Hubbert’s potential (based on fluid mass)?
Or
Should we prefer the potential concept modified by England (based on fluid volume), who took into consideration, the role of the interfacial energy arising from capillary pressure in a porous medium, under the action of the interface (by applying Darcy equation)?
