Abstract
A method for completing a wellbore having a plurality of stimulation valves disposed therein at longitudinally spaced apart locations includes moving a spoolable rod into the wellbore. The rod includes a plurality of spaced apart sensors therein. At least one valve operating dart is applied to an exterior of the spoolable rod. The dart is configured to engage a selected one of the stimulation valves. A position of the at least one dart is estimated during pumping of fluid into the wellbore by measuring output of the sensors in the rod.
