Electric Submersible Pump (ESP) in oilfield is prone to scale deposition, largely due to temperatureincreases by motor heating,and turbulent flow and high shear inside of pump. In this work, the formation of calcium sulphate and calcium carbonatewere studied under a range of conditions that could possibly be encountered in ESPs.The produced water chemistry changes from 100% formation water to mixed formation water and injected seawaterover time.Thescalingtendency and potential mass depositionaresimulatedusing a thermodynamic prediction model. Dynamic scale loop tests were carried outto study the calcium carbonate,calcium sulphate and co-deposition under fieldconditions.The resultsindicate thattherisk of calcium carbonate scale at the initial stage of production in both downhole and ESP. With the breakthrough of seawater, the risk of calcium sulphate scale increases, and harsh calcium sulphate scale could form in ESP.This study also suggeststhat the interference between CaSO4and CaCO3formationis minor under the test conditions.These findings will be used to develop thescale mitigation strategies.
