A method of controlling a downhole system of a coiled tubing system, the method comprising:
- pumping an inflation fluid with a mud pump located in a downhole environment, wherein the inflation fluid includes:
- a clean coiled tubing fluid flowing through a coiled tubing line from a surface source;
- and
- a wellbore fluid external to the coiled tubing line;
- directing the inflation fluid into an inflatable packer local to the mud pump in the downhole environment;
- and
- inflating the inflatable packer in the downhole environment.

A method of controlling a downhole system of a coiled tubing system, the method comprising:
- pumping an inflation fluid with a mud pump located in a downhole environment, wherein the inflation fluid includes a clean coiled tubing fluid flowing through a coiled tubing line from a surface source, and wherein the mud pump draws fluid from both the coiled tubing line and a wellbore in the downhole environment;
- directing the inflation fluid into an inflatable packer local to the mud pump in the downhole environment;
- and
- inflating the inflatable packer in the downhole environment.
