Slide 2
Flow through porous media: from CCS to CCS-EOR
Slide 3
Geological Storage of CO2 The issues: Options 1 to 6 above
cannot be implemented without a detailed knowledge of the
hydrodynamics in the injection locations: the interaction of the
various phases and components (e.g. CO 2 ) within the rock pores.
This can be achieved by modern simulation.

Slide 10
Injection process of gas into the mixture of oil & water
Fixed the pipe diameter, find the optimal gas injection rate, i.e.
optimal the design of valve nozzle diameter and injection pressure
etc. Heat transfer due to bubble generation Gas lift in wells and
risers
Slide 11
Diameter of the internal pipe: 50 to 75mm. Valve nozzle
diameter: 3.2 to 8.0mm Valve injection pressure: 7-12MP Mass flow
rate of the inflow: 30-300 m 3 /day Oil & Water volume rate:
50-100% Compressible gas Pipe length: Gas lift in wells and
risers
Slide 12
N-Phase model for large interfaces Gas lift in wells and
risers
