Grimbeek II polymer pilot is a heterogeneous multilayered fluvial reservoir saturated with viscous oil. Multilayer injection is a challenging condition not only for waterflooding but also for polymer flooding. This is exacerbated because of the water/oil mobility ratio. The workflow consisted on monitoring water saturation variations over time in four injection wells, with respect to the initial open hole and cased hole with oxygen carbon both prior to pilot execution and after two years of polymer injection -Grimbeek petrophysics provide optimum conditions for this type of logs-. Saturation logs after polymer injection showed greater uniformity indicating that vertical sweep efficiency has improved. Quantitative changes in saturation seems to indicate that polymer is 3 times more efficient that water injection CONGTP Thill, Mercedes 745 Riveros, Rubén 746 Ruiz, Ana María 747 Galarza, Maximiliano 734 Kim, Yonghwee 748 Congreso de Exploración y Desarrollo de Hidrocarburos (10mo. : 2018 nov. 5 - 9 : Mendoza) 573 Simposio de Evaluación de Formaciones (2018 nov. 5 - 9 : Mendoza) 675 Saturación de agua 749 Carbono oxígeno 750 Inyección de polímeros 751 128424 128424 https://biblioteca.iapg.org.ar/ArchivosAdjuntos/Conexplor2018/SEF/1188.pdf 0 0 0 0 199346 BVIAPG BVIAPG 068.82 553.28 C62 2018 0015648 2026-03-02 200064921 0 068.82 553.28 C62 2018 0015648 200064921 2026-03-02 23:26:23 2026-03-02 ARCHIVO
