Method and system for detecting one or more properties, positioning, and minimizing tension of a waveguide

A method comprising:

• deploying a fiber optic within a wellbore;
• while deploying, interrogating, using an interrogator of a distributed acoustic sensing system, the fiber optic to determine one or more parameters of the fiber optic;
• and
• responsive to the one or more parameters, controlling the deploying of the fiber optic into a passage of the wellbore, and
• wherein the interrogating comprising interrogating, using the interrogator of the distributed acoustic sensing system, the one or more parameters of the fiber optic while the fiber optic is being conveyed by fluid flow into the vertical portion and the horizontal portion, and
• wherein the fiber optic is positioned in the horizontal portion at a constant fluid flow rate by controlling a speed of a fluid displacement device to minimize change in velocity and/or acceleration of the fiber optic as the fiber optic transitions from a gravity-based deployment to a fluid-propelled deployment.

A system for minimizing tension in a waveguide having a downhole end and an uphole end deployed in a subterranean formation, comprising:

• a sensing system comprising an interrogator;
• a waveguide inventory adjacent the uphole end of the waveguide and in communication with the sensing system;
• and
• a waveguide conveyor coupled to the downhole end of the waveguide,
• wherein the sensing system is configured to (i) receive a signal regarding one or more properties of the waveguide, and (ii) responsive to the one or more properties, controlling the positioning of the waveguide into a passage of a wellbore to minimize damage thereof,
• wherein the passage comprises a vertical portion having a heel and a horizontal portion having a toe,
• wherein the one or more properties of the waveguide are determined using the interrogator while the waveguide is being conveyed by fluid flow into the vertical portion and the horizontal portion, and
• wherein the waveguide is positioned in the horizontal portion at a constant fluid flow rate by controlling a speed of a fluid displacement device to minimize change in velocity and/or acceleration of the waveguide as the waveguide transitions from a gravity-based deployment to a fluid-propelled deployment.
