... Abstract Polymeric scale inhibitors (SIs) possess excellent dispersive and scale inhibition properties. In this study, a series of phosphorous-tagged polymeric SIs (PPSIs) were synthesized to inhibit calcium scale formation in synthetic brines. The design of chemical structure followed previous...

... formation when alkali is mixed with divalent cations. Even when softened water is used as base water, scaling can still be an issue in producing wells due to mixing of waters with different compositions in-situ. Scale control by means of scale inhibitor squeezes on the production side or scale inhibitor...

... treatment for the four MM ASP production wells was completed prior to the ASP slug injection. A shut-in period for each well was applied to ensure adsorption of the chemical to the reservoir rock. Monitoring of the scale inhibitor return profile after the squeeze treatment for each well was carried out...

..., severity of the problem. A range of silicate scale inhibitors has been developed to mitigate problems in oilfields afflicted with silicate scaling due to ASP flooding ( Qing et al. 2002 ). A new test method using an optical scanning device was developed to better characterize inhibition and dispersant...
