  2. Contents • Literature review • Experimental procedures • Software packages used • Economical analysis • HAZOP study • Conclusion

  3. Literature review • Pore throat and pore body • Capillary pressure • Relative permeability

  4. Pore body and pore throat • A porous medium is a complex assembly of irregularly shaped mineral grains with pores. • This complicated structure can be idealized as a collection of relatively large chambers, the pore bodies, connected by narrower openings, the pore throats.

  5. Pore body and pore throat • When fines are moving in the porous medium, they will often be deposited. • The identification of the pore body size is very important for the experiment and injection in real water flooding projects.

  6. Pore body and pore throat

  7. Capillary Pressure • The difference in pressure between two immiscible fluids across the interface between them. • Pc = Pnon-wetting – Pwetting

  8. Relative permeability • It is the ratio of the effective permeability of a phase to the absolute permeability. • Where kri is the relative permeability, ki is the effective permeability and k is the absolute permeability.

  9. Experimental Procedures • Preparing the core samples • Capillary pressure test • Relative permeability measurements
