Subsurface Engineering Intern

We explore and discover the limitless possibilities of energy so we can all progress. We believe in the power of talent to shape the future. That’s why we’re looking for curious, bold individuals who are eager to grow and create new ways forward-people who want to join us in building a more sustainable, innovative, and inclusive world. We strongly believe that diversity fuels creativity and innovation.

That’s why we welcome professionals who are ready to grow, learn, and bring their perspective to the energy challenges of today and tomorrow.

Here, you’ll find a place to grow and unlock your full potential.

Repsol is seeking an engineering student to intern with the Alaska Business Unit during the summer of 2027 in Anchorage, AK. Repsol is one of the top companies in the oil and gas industry. We are present across the entire value chain: exploration and production, transformation, development, and marketing of energy that is efficient, sustainable, and competitive for millions of people.

Repsol is committed to our internship program and helping students enhance their academic studies with real-world, hands-on projects.

As an intern, you’ll work on real projects that deliver tangible benefits and measurable results. At the same time, you’ll have the opportunity to learn about and help to solve some of the most important issues we face. You will experience genuine teamwork, and work alongside highly qualified and experienced colleagues, while you work on live projects and operations. At the end of your internship, you will present your summer project to our staff.

• Mentoring by experienced professionals in your field.
• Increasing levels of challenge and responsibility as skill and industry knowledge grow.
• The opportunity to gain hands-on experience and apply your academic knowledge.
• Exposure to different technical groups and subsurface disciplines across the company.
• Technical and software training.

The successful candidate will be assigned a project within an area of interest to be supervised by a senior member of the Reservoir Engineering Team. The Subsurface Engineering Intern will support the daily and monthly processes used to track, validate, allocate, and report oil, gas, and water production and injection for the newest oil field in Alaska. This role provides hands-on exposure to the full production-volume lifecycle—from wellhead measurement through gathering systems and facility balances to final sales reporting.

The intern will work closely with Reservoir Engineers, Facilities Engineers, Land, Technical Services and Production Accounting to ensure production data is accurate, timely, and aligned with operational realities in the field. This is an excellent opportunity for an engineering student interested in reservoir engineering, production engineering, petroleum engineering data workflows, or production accounting systems in the upstream oil & gas industry.

Learn how to use industry software OFM for production tracking, Petex suite and learn how to build visualizations in PowerBI. How volumes move from the wellhead to sales and how allocation ties the two together. The relationship between allocation engineering, production engineering, measurement, operations, and accounting. How allocation accuracy impacts financial reporting and engineering analysis. Hands-on exposure to real operational challenges in a producing asset during field start-up.
