An 'improved' scale inhibitor to inhibit calcium carbonate formation has been developed. The chemistry of scale inhibitors with the incorporation of synergistic material, a mutual solvent to improve retention in the formation during squeeze treatment is studied. Inadequate knowledge of scale inhibitor chemistry and its interactions with the formation can yield ineffective squeezes. Inappropriately designed squeezes may actually damage the formation. Thus, for inhibitors which are intended for downhole application, it is not sufficient that a particular species inhibits scale; it must also have the appropriate interaction with the formation to give a longer squeeze life time. The inhibitor is also should be compatible with field brines and relatively stable to thermal degradation at reservoir conditions.
