This paper outlines the selection methods for the inhibitor chemical deployed and present the chemical
returns profile from the 3 wells treated (some treatments lasting > 450 days) along with monitoring methods
utilised to confirm scale control in the wells treated.
The paper also explores in detail the issues associated with inhibitor squeeze vs. inhibitor stimulation
deployment in deepwater, subsea fields, many of which are currently being developed in the Campos basin,
Gulf of Mexico and West Africa, and is a good example of best-practice sharing from another oil basin.
