ABSTRACT:
A system for the inspection of a well borehole and the formation around the borehole. The system includes a pair of concentric reeled tubings for injecting a pair of fluids into a wellbore through a wellhead, one of said fluids being an optically transparent or acoustically homogenous fluid which forms a slug of said fluid around an optical sensor which transmits signals indicative of well conditions to the surface. The other of said fluids is used to perform functions with respect to said sensor such as cooling said sensor or protect it from a corrosive environment. In addition, a fiberoptic cable construction in combination with the reel tubing is also disclosed.
