Senior Engineer, Drilling Support

Job Purpose

Senior Engineer, Drilling Operations is responsible for providing comprehensive engineering and operational support for drilling campaigns across PTTEP's offshore assets. The role involves planning and executing drilling operations with a focus on performance optimization, safety, and cost efficiency. The engineer shall leverage deep understanding of offshore drilling rig systems, SIMOPS coordination, and real-time analysis to ensure operational integrity, minimize downtime, and support continuous improvement.

Key Accountabilities

• Provide engineering support for daily drilling operations (offshore jack-ups or floaters), including troubleshooting and technical advice during execution phase.
• Analyze drilling performance (ROP, flat time, trouble time) using historical data and real-time KPIs to identify areas for operational optimization.
• Collaborate with rig teams, service companies, and internal functions to ensure seamless execution with focus on safety, efficiency, and well objectives.
• Actively support SIMOPS planning and execution where drilling operations interface with construction, well intervention, or production activities:
  • Lead risk reviews and interface meetings with relevant disciplines
  • Ensure compliance with PTTEP SIMOPS protocols and procedures
  • Provide engineering judgment on equipment and personnel interface risk during concurrent operations
• Participate in well planning, AFE preparation, and post-well reviews. Contribute to operational risk assessment and mitigation planning.
• Familiar with offshore drilling rig systems, including BOPs, hoisting, mud system, MPD (if applicable), and rig move logistics.
• Support preparation and review of drilling programs, daily instructions (DDIs), and end-of-well reports.
• Monitor real-time operations and proactively engage with offshore teams for technical assurance and rapid decision-making.
• Provide input to continuous improvement efforts, such as well delivery workflows, performance scorecards, and after-action reviews (AARs).
• Assist in mentoring junior engineers and promoting a culture of performance, ownership, and operational discipline.
• Ensure all activities comply with PTTEP’s Well Management System and SSHE standards.

Job End Results:

• To ensure safe, efficient, and cost-effective execution of offshore drilling operations through proactive engineering support, real-time performance analysis, SIMOPS coordination, and continuous operational improvement — resulting in optimized well delivery, minimized non-productive time (NPT), and compliance with PTTEP standards and SSHE policies.

Professional Knowledge & Experiences

• Bachelor’s Degree in Petroleum, Mechanical, or related Engineering field
• 15 years of experience in drilling engineering and offshore operations
• Proven knowledge of offshore rig systems (jack-up, Tender assist), SIMOPS interface, and field troubleshooting
• Experience working in multi-activity environments where simultaneous operations are present (e.g., rig + barge + production platform)
• Strong analytical skills in performance benchmarking, root cause analysis, and risk-based decision-making
• Proficient in drilling reporting and visualization tools (e.g., Wellview, Power BI, OpenWell)
• Effective communicator with strong coordination skills across offshore and onshore teams
