Abstract
A chemical injection system includes an electric submersible pump (ESP) and a fluid chamber. The ESP lifts a production fluid through a production string disposed within a wellbore. The fluid chamber is coupled with the ESP and houses a treatment fluid. The fluid chamber defines, together with a wall of the wellbore, an annulus. The ESP flows at least a portion of the production fluid into the fluid chamber to push the treatment fluid out of the fluid chamber into the annulus, allowing the treatment fluid to flow from the annulus into the ESP to treat the ESP.
