... incremental oil production in carbonate and sandstone core plugs, compared to polymer flooding only. The results showed that higher oil production came from higher differential pressure, which can be attributed to disjoining pressure and pore channel plugging incurred in the porous media. The microsphere...

... set-up and procedures are proposed in this paper. Dual core flooding experiments were conducted at reservoir conditions using live oil, seawater, supercritical CO 2 (sc-CO2), and two composite plugs with different permeabilities. Two composite core plugs, a high permeable core plug (HPCP) and a low...
