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.

Repsol’s student employment program offers the following advantages.

• 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.

About the Role 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.

• 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.

• Handson exposure to real operational challenges in a producing asset during field start up.

• Comparison of production expectations vs actuals and short term forecasting.

Key Responsibilities Daily + Monthly Allocation Support

• Assist with daily welllevel production and injection allocation for oil, gas, and water volumes. Tracking pressure and temperature data and end of month corrections.

• Help identify and reconcile discrepancies in production data, build a database and visualizations using OFM and PowerBI.

Data Quality & Systems

• Update and maintain production data in allocation systems and production analysis (e.g., Energy Components, Oil Field Manager(OFM)).

• Assist in building Power BI dashboards for visualization of production trends or allocation accuracy.

Operations & Engineering Support

• Work with Reservoir Engineers to monitor performance trends, identify unusual production behavior, or flag potential well or facility issues.

Required Qualifications

• Fully authorized to work for any employer in the US without sponsorship now or in the future. Additionally, we are not authorized for employment under OPT/CPT/F1 visa programs.

• Successful completion of 2 years towards a Bachelor's (or higher) in an Engineering discipline - Petroleum and Geosciences preferred, but open to other engineering disciplines.

• Students with an expected graduation 2028-2029 are encouraged to apply (juniors or sophomores). May 2027 graduates may only be considered if enrolled in a post-graduate program.

• Must have cumulative and major GPA of 3.3 or higher, to be confirmed with transcript (unofficial transcript is acceptable)
