With increasing volumes of produced or effluent water during oil and gas operations, it is necessary to maintain a proactive approach to control the formation of sulphate and carbonate scales to maintain flow assurance and integrity of the production system. The potential for scale problems exists whenever the fluid produced from a reservoir contains water. As the well matures and more hydrocarbon is extracted from the reservoir, the water table in the reservoir rises, water begins to be produced and the potential for scale deposition increases.

ChampionX was contracted by an operator in Nigeria to develop a customized scale inhibitor monitoring program for the surface facilities and seawater flood systems of an FPSO, which was producing 230,000 bbl/d of oil, 40,000 bbl/d of water and 260,000 bbl/d of seawater injection.
