Abstract
Methods and apparatuses used with coiled tubing are disclosed. A method of inserting a fiber optic cable into coiled tubing is provided. The method comprises providing a coiled tubing having a first opening at a first end of the coiled tubing and a second opening at a second end of the coiled tubing. The fiber optic cable is fed into the first opening of the coiled tubing so that the fiber optic cable advances inside the coiled tubing along a direction from the first end to the second end. The fiber optic cable is vibrated during the feeding of the fiber optic cable into the coiled tubing.

A method of monitoring an environmental condition inside a wellbore comprising:
- providing a coiled tubing used for operations in the wellbore, the coiled tubing having a first opening at a first end of the coiled tubing and a second opening at a second end of the coiled tubing;
- feeding a fiber optic cable into the first opening of the coiled tubing so that the fiber optic cable advances inside the coiled tubing along a direction from the first end to the second end;
- vibrating the fiber optic cable while feeding the fiber optic cable;
- inserting the coiled tubing comprising the fiber optic cable into the wellbore;
- and
- monitoring the environmental condition via signals transmitted along the fiber optic cable.
A method of monitoring a parameter of a bottom-hole assembly inside a wellbore comprising:
- providing a coiled tubing used for operations in an oil or gas well, the coiled tubing having a first opening at a first end of the coiled tubing and a second opening at a second end of the coiled tubing;
- feeding a fiber optic cable into the first opening of the coiled tubing so that the fiber optic cable advances inside the coiled tubing along a direction from the first end to the second end;
- vibrating the fiber optic cable while feeding the fiber optic cable;
- inserting the coiled tubing comprising the fiber optic cable into the wellbore;
- and
- monitoring the parameter of the bottom-hole assembly via signals transmitted along the fiber optic cable.
An apparatus for inserting a fiber optic cable into a coiled tubing used for operations in an oil or gas well comprising:
- a cable feeding mechanism configured to feed the fiber optic cable into the coiled tubing so that the fiber optic cable is inserted into a first opening at a first end of the coiled tubing and is advanced in a direction from the first end to a second end of the coiled tubing, wherein the cable feeding mechanism is configured to vibrate the fiber optic cable while feeding the fiber optic cable;
- and
- a controller configured to:
- monitor a rate of feeding the fiber optic cable into the coiled tubing;
- monitor vibration parameters;
- and
- control the rate of feeding the fiber optic cable into the coiled tubing.
