Fiber Engineer - Well Services

Role Overview

Fiber Engineer - Well Services at Weatherford UAE. This is a field-intensive position supporting technically advanced well-surveillance projects involving conveyance optic cable to acquire DAS and DTS data in real time.

Role Purpose

Design, deploy, and operate distributed fiber optic sensing systems for real-time downhole data acquisition across the full operational cycle, from pre-job engineering through downhole fiber deployment, interrogator setup, and data quality control in live production and injection wells.

Key Responsibilities

Pre-Job Engineering & Planning

• 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.
• Provide technical input for RFQs, scope of work documents, and vendor qualification assessments related to fiber optic sensing and through-tubing DFOS contracts.

Fiber Deployment & Splicing

• Execute fiber optic splicing (fusion and mechanical), connector preparation, and optical loss management to maintain signal integrity across downhole fiber runs.
• Troubleshoot deployment anomalies including fiber breaks, high attenuation events, and mechanical obstructions, performing root cause analysis and corrective actions.

Testing & Verification

• Conduct pre-job and post-job OTDR testing and optical verification to confirm fiber continuity and performance.

System Configuration & Operation

• 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.

Vendor & Data Management

• Liaise with interrogator vendors for technical support, software updates, and calibration prior to field mobilization.
• Archive acquired data in vendor-specific and non-proprietary formats with proper metadata tagging, depth/time referencing, and handover documentation.

Qualifications & Experience

• 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.

Skills & Competencies

• 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.
