Senior Drilling Engineer

Job Description

• Support the group's AI transformation in drilling: Procurement support and tender evaluation, data-driven well planning, real-time monitoring, performance analytics, and digital tools across all projects.
• Implement corporate best practices in processes and standardisation such as a Well Operations Management Plan (WOMP), adapted for each unique operational jurisdiction
• Design wells end to end, from the Basis of Design (BOD) to casing and cementing programmes, trajectories, mud, completion, workover and well testing design, materials for corrosive brines and H₂/He, and well integrity through to plugging and abandonment (P&A).
• Define the scope of work, review and integrate engineering study results prepared by external drilling engineering service providers.

• Prepare drilling programmes, cost estimates (AFEs) and schedules; build the business case with each OpCo.
• Lead rig and service-contractor selection, run tendering processes and carry out the technical evaluation of drilling contracts, contract strategy and insurance.
• Supervise operations on site when needed and remotely otherwise; act as the group's technical authority on drilling.
• Own drilling risk: well control, HSE, induced seismicity, aquifer protection, lost circulation, pore pressure, wellbore stability in subsalt, fractured, and karstified formations
• Prepare technical files for permits and regulators in Europe, North America and APAC.
• Contribute to consulting mandates: reviews, audits, drilling plans and expert opinions for clients.
• Build the group's drilling standards and lessons-learned base, and mentor junior engineers.

Qualifications

• At least 15 years of drilling engineering experience, mostly in oil and gas, with both office design and wellsite exposure.
• Proven experience drilling carbonate reservoirs.
• Proven experience in fractured formations: losses, stability, and the drilling and completion choices they drive.
• International track record across several basins and operators, onshore and preferably offshore.
• Strong knowledge of the drilling contractor and well-services market, and of tendering processes.
• Deep, high-temperature or high-pressure wells, hard-rock drilling and advanced technologies (e.g. MPD) are a strong plus; geothermal, helium or hydrogen experience is welcome but not required.
• Degree in petroleum, drilling or mechanical engineering, or equivalent; IWCF or IADC well-control certification.
• Fluent English; French and German are a plus.
• Recognized references in the discipline and genuine interest in the energy transition.
