These discoveries not only enrich the theoretical connotation of the waterflood huff-and-puff technology but also...

... can bring higher recovery rate to this brownfield. Even for the entire China market, this was the first time that the new multilayer boundary detection service was introduced. This paper illustrates an exemplary case study of using this innovative technology for a better understanding of reservoir...

..., we set the oil production rate less than 10 t/d as the drainage stop-condition. The 50 orthogonal test plans and simulation results are shown in Table 3 . We collected the oil recovery factor, recovery rate and cumulative oil steam ratio (COSR) of each test plan. Then the grey relational analysis...

... concentration of polymer changing from 0.5g/L, 1.0g/L and 2.0g/L, the improving value of recovery rate is 25.26%, 21.05% and 22.1% respectively. After water flooding, with the changing of mass concentration of Sodium carbonate on ASP from 0.3%, 0.6%, 1.0% and 1.5%, the recovery rate of ASP systems is 25.26...
