Abstract
This paper presents an in-depth study and analysis of the effect on relative permeability shape on well clean up and squeezes life of a treatment for a Mutual Solvent deployed squeeze treatment.
 The study revealed that the shape of the relative permeability curve had impact on the well clean up time but the shape of the relative permeability curves do not generally impact greatly on the extent of the squeeze life.
 Impact of squeeze life for straight (miscible) relative permeability curves however is greater than for curved (non-miscible) relative permeability’s.
The finding showed that well clean up and squeeze life time is wetting specific, well clean-up time is faster for the strongly water wet system and mix-wet systems than oil wet systems at lower water cuts and/or water saturations but at higher water cuts and saturations the signatures are different. The studies is in its second stage where studies is been done on multi layered cases.
