Corrosion Protection with Chemical Injection Centralizer
Preventing the adverse effects of wellbore corrosion is an ongoing battle during production operations. While highly effective, chemical injection for corrosion protection also creates a a dilemma in that injecting too little may not stop the corrosion or buildup, but adding too much wastes product and can create downstream emulsion issues.
When installed below electric submersible pump (ESP) motors, our chemical injection centralizer serves as an ESP system centralizer with the additional capability of a chemical injection system. The uniform 360-degree spray ensures even dispersion that reduces the risks of single-dispersion injections while enhancing ESP performance and reliability. Additionally, the centralization function of the chemical injection centralizer allows equal spacing between the motor and casing, which provides equal flow paths for the production fluid to flow – preventing hotspots in the motor and increasing ESP motor cooling.
Forum’s chemical injection centralizers are part of our extensive Multilift artificial lift solutions catalog.
