✨ AI Summary
The Fiber Engineer is an experienced fiber optic specialist supporting technically advanced well-surveillance projects involving conveyance optic cable to acquire DAS and DTS data in real time. The role covers the full operational cycle, including pre-job engineering, downhole fiber deployment, multi-vendor interrogator setup and operation, and data quality control. This is a field-intensive position requiring proven expertise in distributed fiber optic sensing (DFOS) and through-tubing intervention practices. Responsibilities include planning and supervising fiber optic cable deployment, managing reel preparation, fiber termination, and surface connection to interrogation units. The engineer will execute fiber optic splicing, conduct OTDR testing, troubleshoot deployment anomalies, and set up/configure/operate multi-vendor DAS and DTS interrogation systems. They will also monitor real-time data, archive acquired data, and liaise with interrogator vendors for technical support. The role requires hands-on proficiency in splicing, OTDR analysis, optical loss budgeting, and fiber characterization, along with operational experience with interrogator systems and the ability to interpret DAS and DTS data. Familiarity with different fiber types and proficiency in managing DFOS datasets is also necessary.

Description
Job Overview
The Fiber Engineer is an experienced fiber optic specialist supporting technically advanced well-surveillance projects involving conveyance optic cable to acquire DAS and DTS data in real time. The role covers the full operational cycle, including pre-job engineering, downhole fiber deployment, multi-vendor interrogator setup and operation, and data quality control. This is a field-intensive position requiring proven expertise in distributed fiber optic sensing (DFOS) and through-tubing intervention practices.
 
Responsibilities
  • Plan and supervise deployment of fiber optic cable within capillary tubing for through-tubing conveyance in live production and injection wells.
  • Manage reel preparation, fiber termination, and surface connection to interrogation units.
  • Execute fiber optic splicing (fusion and mechanical), connector preparation, and optical loss management to maintain signal integrity across downhole fiber runs.
  • Conduct pre-job and post-job OTDR testing and optical verification to confirm fiber continuity and performance.
  • Troubleshoot deployment anomalies including fiber breaks, high attenuation events, and mechanical obstructions, performing root cause analysis and corrective actions.
  • Set up, configure, and operate multi-vendor DAS and DTS interrogation systems.
  • Configure acquisition parameters including pulse repetition frequency (PRF), gauge length, channel spacing, sampling frequency, and measurement range in line with well objectives and vendor operating envelopes.
  • Monitor real-time data streams during acquisition, identify anomalies, and adjust acquisition parameters on-site to optimize signal-to-noise ratio and data quality.
  • Archive acquired data in vendor-specific and non-proprietary formats with proper metadata tagging, depth/time referencing, and handover documentation.
  • Liaise with interrogator vendors for technical support, software updates, and calibration prior to field mobilization.
  • Provide technical input for RFQs, scope of work documents, and vendor qualification assessments related to fiber optic sensing and through-tubing DFOS contracts.
 
Skills
  • Hands-on proficiency in fusion splicing, mechanical splicing, OTDR trace analysis, optical loss budgeting, and fiber characterization.
  • Operational experience with two or more interrogator systems.
  • Ability to generate and interpret DAS waterfall plots and DTS temperature profiles, and recognize flow, leak, and valve-operation signatures using vendor software.
  • Familiarity with single-mode, multi-mode, and specialty-coated fibers and their mechanical and thermal performance under downhole conditions.
  • Proficiency in managing large DFOS datasets, including structured archiving, time/depth alignment, and preparation of clean data handover packages for clients.
 
Qualifications
  • Bachelor’s degree in petroleum, electrical, optical/photonics engineering, or a closely related technical discipline.
  • Minimum of 6 years of experience in oilfield services, specifically in DFOS operations.
  • IWCF or WELL SHARP Well Control certification preferred.
