Publication number: 20240011804Abstract: A method 200, system and device for range finding are provided. The method 200 comprises determining 204 a first optical signature of a spool of optical fibre 16 wound in a winding pattern. The winding pattern comprises repeated changes in a winding parameter to provide a different optical response such that the first optical signature comprises a plurality of markers representing each change in the winding parameter. The method 200 further comprises despooling the fibre 16 from the spool; determining a second optical signature of the spool of optical fibre 16 after despooling the fibre 16 from the spool; and calculating 208 the length of despooled fibre based on a comparison of the first and the second optical signatures. The determined length may be used to determine a range of the spool of optical fibre 16 deployed in a wellbore.Type: ApplicationFiled: August 13, 2021Publication date: January 11, 2024Applicant: Well-Sense Technology LimitedInventor: Daniel George PURKIS
