Abstract The objective of the study was to estimate which was the effective mobility of a polymer solution injected in an extra heavy oil reservoir, also try to stablish if there was a reduction on effective permeability as injection progressed, and finally estimate the mobility ratio between...

... in temperature. Corefloods demonstrated excellent injectivity due to the low initial viscosity (∼1.1 cp) of the GALKA system similar to brine viscosity. This was confirmed by the mobility reduction, (RF∼2.1) which was close to the measured relative viscosity value during GALKA injection. Stable gel formation...

The principle for controlling gelant injection and the method for forecasting water shutoff performance are also included. The successful application is based on two requirements: (1) gelant can penetrate a short...

Carbonate reservoirs are mostly naturally fractured and the matrix for such reservoirs are strongly oil-wet to mixed-wet. The use of surfactants leads to a reduction in surface...

... the experimental results. We show that the optimum microemulsion-to-oil viscosity ratio is roughly 5 to 6 without co-solvent, but it can be reduced to a more favorable ratio of ~2 by adding co-solvent. Even though the amount of co-solvent needed is case dependent, a clear trend of microemulsion viscosity reduction...
