... of water followed by 3 PV of polymer at 0.6 ml/min. As was discussed above, polymer is added to water to increase its viscosity and reduce its mobility. Compared to water and surfactant, polymeric displacements (i.e. polymer and SP) exhibit a marked improvement in the sweep efficiency. In Fig.25...

...-branched polymer fracturing fluid in low-permeability heavy oil reservoirs. A hyper-branched polymer, which has numerous end groups and possesses a special highly branched three-dimensional spherical molecular structure, is characterized by Fourier Transform Infrared (FTIR) spectrophotometer. Laboratory...

... this methodology to the Pelican Lake field in Alberta. We evaluated water flooding, polymer flooding, alkaline-surfactant-polymer (ASP) flooding, alkaline-co-solvent-polymer (ACP) flooding and polymer flooding followed by ASP flooding in laboratory tests. We executed new experiments including microemulsion phase...

... and the wet scan. Combining equations (1) and (3) , Abstract Three experiments have been performed, injecting brine and polymer into a sand pack saturated with heavy oil. Each experiment was imaged with time lapse X-ray CT. The first two experiments, conducted in a medical scanner with a resolution...

... of polymer concentration and rotation speed (shear rate) at the reservoir temperature of 30°C. As expected, all the polymeric solutions exhibited pseudo-plastic behaviour, i.e., apparent viscosity decreases with increasing shear rate. To study the effect of surfactant SS-880 on polymer solution viscosity...
