    Investigation of Carbonated Water Injection in an Oil Reservoir to Enhance Oil Recovery

    Abdollah Esmaeili1;
    Type of Paper: Keynote
    Id Paper: 13
    Topic: 17


    In this paper, according to actual condition of an oil field, a new enhanced oil recovery method called carbonated water injection (CWI) was designed and tested for this oil field. In carbonated water, CO2 exists as a dissolved phase as opposed to a free phase, eliminating the problems of gravity segregation and poor sweep efficiency, which are characteristics of a typical CO2 injection project. In fact, both viscosity and density of water increase as a result of the dissolution of CO2 in water. Recovery efficiency of this EOR method was tested experimentally using several cores of this sandstone reservoir. Reservoir rock and fluid properties changing during this process were investigated. For this purpose, a set of experimental tests based on core flooding tests on sandstones were designed. The results show that carbonated water injection (CWI), compared to conventional water injection, improves oil recovery in both secondary (pre-water flood) and tertiary (post-water flood) injection modes.
