Abstract
A method of drilling a wellbore can include drilling the wellbore with a continuous tubing drill string, and sensing at least one parameter with an optical waveguide in the drill string. A well system can include a continuous tubing drill string, and an optical waveguide in the drill string. The optical waveguide may sense at least one parameter distributed along the drill string.
Claims30
A method of drilling a wellbore, the method comprising:
- drilling the wellbore with a continuous tubing drill string;
- and
- sensing at least one parameter with an optical waveguide in the drill string, the sensing comprising detecting optical back scatter along the optical waveguide.
A well system, comprising:
- a continuous tubing drill string;
- and
- an optical waveguide in the drill string,
- wherein the optical waveguide senses at least one parameter along the drill string, via detection of optical back scatter along the optical waveguide.
