A system and method for profiling and modifying fluid flow through a wellbore. The system comprises a logging system, a downhole unit, and a deployment system. The logging system comprises a logging tool. The downhole unit is operable to house the logging tool. In addition, the downhole unit is operable to selectively secure a retrievable fluid barrier within a wellbore casing. The deployment system is operable to deploy the downhole unit in the wellbore casing. The method comprises deploying the downhole unit into the wellbore and securing the retrievable fluid barrier below a first group of perforations. The method also comprises operating the logging tool to detect a wellbore fluid parameter.

Production profile determination and modification system

A system for removing solid particulates from a production fluid. The system includes a solid separator to remove the solid particulates from the production fluid to reduce pump component wear. The system is disposed in a wellbore such that wellbore fluids are drawn into the solids separator before entering the submersible pump. Solid particulates are separated from the fluid that flows through the solids separator before entering the submersible pump. The solid particulates are routed past the submersible pump. The solid particulates may be reinjected into the fluid discharged from the pump.
