About The Position

Repsol is seeking an engineering student to intern with the Alaska Business Unit during the summer of 2026 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. 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 handson exposure to the full productionvolume 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.
