1. A method of treating a subterranean formation intersected by a wellbore comprising the steps of:

  • deploying a fiber optic tether into a coiled tubing, the fiber optic tether having a degree of slack relative to the coiled tubing;

    deploying the coiled tubing, a borehole tool and a sensor into the wellbore;

    optically connecting the fiber optic tether to the borehole tool and the sensor;

    performing a stimulation well treatment operation with the borehole tool, wherein the stimulation well treatment operation comprises at least one adjustable parameter;

    operating the sensor to obtain a measured property related to the stimulation well treatment operation;

    using the fiber optic tether to convey the measured property; and

    adjusting the least one adjustable parameter of the stimulation well treatment operation in real time based on the measured property.
