Patent number: 11366275Abstract: A hybrid electro-optic (EO) wireline cable includes optical fibers strategically placed within to allow acoustic sensing methods as well as provide power and electrical telemetry. The hybrid EO wireline cable contains optical fibers in the interstices among symmetrically arranged electrical wire bundles to allow a hybrid EO cable to be concurrently used for electrical telemetry and optical fiber sensing without interference in a wellbore environment. This hybrid EO cable maintains electric and magnetic field symmetry which allows an optimal electrical signaling rate through orthogonal propagation modes. By placing optical fibers symmetrically inside the interstitial spaces between electrical wire bundles, the cable maintains its optimal signaling rate and avoids the mechanical and electrical limitations that would be introduced when combining electrical wires and optical fibers in a wireline cable.Type: GrantFiled: September 27, 2019Date of Patent: June 21, 2022Assignee: Halliburton Energy Services, Inc.Inventors: John Laureto Maida, Sudhir Kumar Gupta, Michel Joseph LeBlanc, Arabinda Misra, Ramon Hernandez Marti
