Claim:
1. A method of performing a wellbore operation in a subterranean wellbore of a subterranean formation comprising: deploying a coiled tubing and an optical fiber tether into the wellbore, the optical fiber tether disposed in a fluid flow path of the coiled tubing, wherein the optical fiber tether defines a small cross-sectional area configured not to impede the fluid flow path of the coiled tubing, thereby not interfering with the use of the coiled tubing for pumping fluids in well treatment operations, the optical fiber configured to make a distributed range of measurements across an interval of the wellbore; performing the wellbore operation, the wellbore operation comprising the use of a well treatment fluid flowing from a surface of the wellbore along the fluid flow path of the coiled tubing and passing the well treatment fluid out of the coiled tubing for contact with and treatment of the subterranean formation; obtaining a measured property related to the wellbore operation; sending the measured property to a control system over the optical fiber; adjusting the wellbore operation based on the measured property; and removing the coiled tubing and optical fiber tether from the wellbore after completing the wellbore operation.
