... oil recovery through polymer flooding was studied by conducting linear displacement experiments in sandpacks with different permeabilities. The viscosity of oil samples used for different experiments ranged from 1000 to 8400 cP. The polymer solution used for this study was high molecular weight...

... studied. This paper investigated the potential of polymer flooding for heavy oil reservoir using a heavy oil of 1,450 mPa.s. Tertiary polymer flooding tests were performed in both homogeneous and heterogeneous (channelled) sandpacks. Results in homogeneous sandpacks showed that there existed a viscosity...

... to investigate the influences of fraction of perforated length, total length, and fractures, which do not intersect with well axis, on the productivity of horizontal wells. An experimental model (60 cm X 40 cm X 20 cm) was designed and used to achieve the study objectives. Carefully sized sandpacks were used...

.../surfactant/polymer) injection strategy. Coreflood tests used either sandpacks or composite reservoir cores with a selected medium crude oil. Injected surfactant concentration, slug size, chasing fluid, and residual oil saturation were the varied parameters. The optimal surfactant concentration of 0.15 wt...

... combustion front propagation through the sandpack, at all oil layer thicknesses, 0.1m, 0.2m and 0.4m. The combustion front peak temperature increased with increasing oil layer thickness, reaching 700 ~ 800oC. However, increasing the oil layer thickness had little effect on oil recovery, or the API gravity...

The 3-D simulation result predicts a very stable combustion front profile, which propagated stably and completely to the end of the sandpack. Overall oil production...
