Paper Number: SPE-209668-MS
.... Andersen et al. (2019a) found that viscous coupling would affect co-current imbibition tests by reducing the fraction of counter-current oil production. Tantciura et al. (2021) found that nonstandard observations such as two distinct square root recovery trends in tight rocks or delayed onset...

... Abstract The injection of Sulphonated-smart water (SW) could be an attractive application as it results in the formation of a mechanically rigid oil-water interface, and hence possible higher oil recovery in combination with the polymer. Therefore, detailed experimental investigation and fluid...

... fingering for a better oil recovery. The effect of polymer addition to water is not only to increase the water viscosity but also to reduce the water relative permeability leading to more favorable mobility contrast. Skauge et al., (2014) , show the development of viscous fingering in a bentherimer...
