Systems and methods for deploying and retrieving magnetically coupled temporary wireline fiber for broadside wave detection

A magnetic clamp for a wireline fiber assembly, comprising:

• a clamp body extending along a longitudinal axis, the clamp body comprising:
• a central bore configured to receive a fiber optic cable;
• and
• a first and a second body portion, wherein the first and second body portions each comprise at least one face surface defining a plane substantially parallel to the longitudinal axis, and comprise at least one tapered end;
• one or more magnets each having a substantially cylindrical or disk shape, the one or more magnets positioned between the first body portion and the second body portion, wherein the one or more magnets protrude beyond an exterior surface of the clamp body for contact with a casing of a wellbore.

A method of deploying and retrieving a wireline fiber assembly in a wellbore during a downhole monitoring campaign, the method comprising:

• deploying the wireline fiber assembly into the wellbore having a wellbore axis, the wireline fiber assembly comprising a fiber optic cable and a plurality of magnetic clamps attached to the fiber optic cable;
• magnetically coupling the plurality of magnetic clamps in a substantially helical arrangement along an inner surface of a casing of the wellbore;
• applying magnetic coupling strength sufficient to maintain coupling of the plurality of magnetic clamps to the inner surface of the casing, while remaining below a pullout load rating or a rig-in load rating of surface equipment;
• monitoring wireline load during deployment of the wireline fiber assembly such that the wireline load remains below a working load safety limit;
• decoupling the plurality of magnetic clamps from the inner surface of the casing;
• and
• retrieving the wireline fiber assembly from the wellbore.
