Key Responsibilities
Downhole Fiber Deployment — Through-Tubing Capillary Conveyance
- Plan and supervise deployment of fiber optic cable within capillary tubing for through-tubing conveyance in live production and injection wells — applying the specific combination of DFOS engineering expertise and through-tubing intervention knowledge that safe, reliable downhole fiber deployment in live well conditions requires, managing the deployment planning process from wellbore geometry analysis and capillary tubing sizing through surface reel setup, downhole conveyance execution, and final fiber-to-interrogator connection in a way that maintains well integrity, protects the fiber from deployment damage, and positions the fiber sensing cable at the correct depth zones for the surveillance objectives the program is designed to achieve
- Manage reel preparation, fiber termination, and surface connection to interrogation units — applying the systematic pre-job preparation discipline that ensures the capillary-conveyed fiber assembly is correctly prepared at the surface (reel conditioning, fiber end-face inspection, connector cleaning and polishing, optical insertion loss testing) before downhole deployment begins, and that the surface-to-interrogator connection achieves the optical return loss and insertion loss specifications required for the DAS and DTS acquisition parameters planned for the job
- Troubleshoot deployment anomalies including fiber breaks, high attenuation events, and mechanical obstructions — applying systematic OTDR-based fault location, optical power budget analysis, and field-engineering problem-solving to diagnose and resolve the specific downhole deployment problems (mechanical damage during conveyance, splice degradation, connector contamination, tube collapse) that arise during through-tubing fiber deployment in live well environments, performing root cause analysis and implementing corrective actions that restore fiber continuity and optical performance to specification within the constraints of the well’s operational schedule
- Apply knowledge of single-mode, multi-mode, and specialty-coated fiber types — selecting and handling the specific fiber type appropriate for the downhole temperature, pressure, and chemical environment of the target well (gold-coated, carbon-hermetically sealed, polyimide-coated, or standard acrylate-coated single-mode fiber for DAS; multi-mode or gradient-index fiber for DTS depending on interrogator specification) and managing fiber handling and deployment procedures appropriate to each fiber type’s specific mechanical and thermal performance characteristics
Fiber Optic Splicing — Fusion, Mechanical & OTDR Verification
- Execute fiber optic splicing (fusion and mechanical) and connector preparation to maintain signal integrity across downhole fiber runs — performing the precision fiber preparation, cleaving, alignment, and arc fusion splicing operations that produce the minimum insertion loss splices required for downhole fiber assemblies where optical loss budget is tightly constrained by the interrogator’s minimum required optical return power and the cumulative attenuation of the downhole fiber run, and where splice re-work is extremely difficult or impossible once the fiber is downhole
- Conduct pre-job and post-job OTDR testing and optical verification — executing the systematic OTDR measurement protocol (multiple test wavelengths, bidirectional measurement, event table documentation) that characterizes the complete downhole fiber run’s optical performance before and after deployment, confirming fiber continuity, measuring splice insertion losses, identifying backscatter anomalies that indicate potential mechanical damage, and verifying that the complete fiber path’s optical performance is within specification for the planned DAS and DTS acquisition requirements
- Manage optical loss budgeting — calculating and tracking the optical power budget for each downhole fiber deployment, accounting for fiber attenuation (dB/km at the operating wavelengths), splice insertion losses, connector losses, and interrogator output power and sensitivity specifications to confirm that the complete fiber path will deliver adequate optical return power for reliable DAS and DTS signal acquisition at the planned acquisition parameters
DAS/DTS Interrogator Operation — Multi-Vendor Configuration & Real-Time Monitoring
- Set up, configure, and operate multi-vendor DAS and DTS interrogation systems — demonstrating practical operational proficiency with two or more commercial interrogator platforms (Silixa, Fotech, Luna, AP Sensing, Bandweaver, or equivalent vendors), including the specific software interface, hardware connection, and initial calibration procedures for each vendor’s system, and the ability to select and configure the acquisition parameters that best suit the specific well surveillance objectives for each job
- 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 — applying detailed understanding of how each acquisition parameter affects the DAS system’s spatial resolution, frequency response, dynamic range, and signal-to-noise ratio to select the parameter combination that best suits the specific well surveillance targets (flow profiling, leak detection, fracture monitoring, valve operation detection) within the constraints of the interrogator’s operating specifications
- Monitor real-time data streams during acquisition, identify anomalies, and adjust acquisition parameters on-site to optimize signal-to-noise ratio and data quality — maintaining active technical oversight of the DAS waterfall and DTS temperature profile displays during acquisition, recognizing the acoustic and thermal signatures that indicate flow, leak, valve operation, and other well events, distinguishing genuine well events from noise artifacts and acquisition system anomalies, and making informed real-time parameter adjustments that improve data quality without disrupting ongoing acquisition
Data Management, Archiving & Technical Documentation
- Archive acquired DAS and DTS data in vendor-specific and non-proprietary formats with proper metadata tagging, depth/time referencing, and handover documentation — applying the structured data management discipline that ensures acquired fiber optic surveillance data is correctly formatted, completely described, properly organized, and compliantly handed over to the client in a way that supports independent third-party analysis, long-term data storage, and integration with the client’s well database and subsurface interpretation workflows
- Manage large DFOS datasets including structured archiving, time/depth alignment, and preparation of clean data handover packages — handling the specific data volume and format challenges of multi-day DAS continuous acquisition datasets (which can reach terabyte scale) with the systematic file organization, compression, format conversion, and quality check methodology that makes DFOS data sets usable by clients and third-party analysts rather than unusable archives of raw acquisition files
- Provide technical input for RFQs, scope of work documents, and vendor qualification assessments — contributing the field-level DFOS technical expertise and multi-vendor operational knowledge that helps the commercial and engineering teams produce technically accurate, operationally realistic, and competitively differentiated proposals and vendor assessments for fiber optic sensing and through-tubing DFOS contracts
Qualifications & Requirements
Educational & Certification Requirements
- Bachelor’s degree in Petroleum Engineering, Electrical Engineering, Optical/Photonics Engineering, or a closely related technical discipline — providing the engineering foundation for DFOS system understanding, fiber optic physics, and downhole well environment technical competence
- IWCF (International Well Control Forum) or WELL SHARP Well Control certification — preferred for this live well, field-intensive role where well control awareness is an essential safety competency
Experience Requirements
- Minimum 6 years of experience in oilfield services specifically in DFOS operations — with demonstrated operational delivery of downhole fiber conveyance, DAS/DTS acquisition, and DFOS data management across multiple well surveillance projects
- Hands-on proficiency in fusion splicing, mechanical splicing, OTDR trace analysis, optical loss budgeting, and fiber characterization — verified through operational track record rather than theoretical training alone
- Operational experience with two or more DAS/DTS interrogator systems — from different vendors, demonstrating the multi-vendor flexibility that field DFOS operations in Abu Dhabi require
- Ability to generate and interpret DAS waterfall plots and DTS temperature profiles, and recognize flow, leak, and valve-operation signatures using vendor software
