“…Water relative permeability (krw) and oil relative permeability (kro) intersect at a value less than 0.5, indicating that the mobility ratio is less than one and the polymer solution wets the porous media surface. Figure 6 depicts a wet reservoir in which the 2500ppm PAM/brine water is an excellent candidate for chemical tertiary recovery [43,44].The actual core's circular cross-section was turned into a square cross-section with the same cross-sectional area (Figure2) and grid sizes of 2.22 cm along the y-and z-axes to aid in the development of a numerical simulation model of core flooding. The minimum bottom hole pressure in the numerical simulation model was set to 345 Psi since the production end was exposed to the atmosphere during core flooding.…”

The polymer recovery efficiency of cationic polyacrylamide (PAM) has been evaluated for use as polymer flooding in the Basra oil reservoir Initially, rheological, physical and petro physical were studied. Additionally, the polymer flooding core flooding experiment has been tested to see how well PAM solutions can be recovered. The comparative study between experimental and numerical study for PAM solution has been accomplished in terms of rheological properties , relative permeability curve and oil production. The results showed that PAM solution exhibit shear thinning effect which can efficiently improve the macroscopic sweep efficiency as well as microscopic displacement efficiency, and viscosity increase with high concentration. The overall recovery efficiency of 94.61 % from sandstone was determined for 2500ppm PAM flooding. By contrast, brine water flooding was found to be 47.76%, showing that it was less effective than PAM solution. Cost analysis is another factor that affects a project's success. To support the experimental results, a simulation by the Computer Modelling Group (CMG) study has also been conducted.
