Real time downhole intervention during wellbore stimulation operations

摘要

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.

1. A method for completing a wellbore having a plurality of stimulation valves disposed therein at longitudinally spaced apart locations, said method comprising the following steps:
moving a spoolable rod into the wellbore, the rod including a plurality of spaced apart sensors therein; applying at least a first valve operating dart to an exterior of the spoolable rod; the at least a first dart configured to engage only a selected one of the stimulation valves; and pumping of fluid into the wellbore and the pumped fluid thereby moving the at least a first dart along the spoolable rod to engage the selected one of the stimulation valves.
