ORLEN Upstream Norway AS (OUN) is an oil and gas company that is growing and we are searching for a Principal/Senior Development & Production Geophysicist.

The successful candidate will report to a Subsurface Manager and work across the full OUN portfolio. The Subsurface department is responsible for 25 producing and 7 developing assets across 7 OUN core areas: Goliat, Skarv, Ormen Lange, Duva/Kvitebjørn, Yggdrasil, Sleipner and Tommeliten.

Over the next 12 months the Subsurface Department will be responsible for following the drilling of up to 35 production wells, taking 13 developments through internal project decision gates, including 6 for FID, as well as performing 3D/4D interpretation and updates to several geo- and simulation models.

The role will be responsible for interpreting geophysical and other relevant data to optimise recoverable hydrocarbon potential in OUN’s development and production assets, while supporting investment decisions through high-quality geophysical analysis. The successful candidate will conduct geophysical evaluation of existing assets and M&A opportunities in a multidisciplinary environment, support production and inn-fill drilling activities, review operators’ work, represent and convey OUN's position in licence committees, and progress projects through decision gates to deliver production growth targets across the portfolio.

This is an exciting opportunity to join an international team of highly motivated and dedicated colleagues, working in a fast-paced and rewarding environment.

Duties and responsibilities

Asset Support

• Define and perform geophysical interpretation needs to support reservoir monitoring and development across producing assets.
• Advise Subsurface Managers on development and production geophysical support.
• Provide technical guidance to other development and production geophysicists.

Interpretation and Reservoir Characterisation

• Perform 4D seismic feasibility studies.
• Interpret 3D and 4D seismic data for static and dynamic reservoir models.
• Use seismic attributes for reservoir characterisation in field assessments and volumetric uncertainty studies.
• Integrate subsurface data to mature upside potential in developing and producing assets.
• Keep up to date with new technologies and best practices in production and development geophysics.

Data, Uncertainty and Risk

• Integrate well, seismic, geological, and other data to improve interpretation and up-to-date subsurface understanding and reduce uncertainty.
• Identify subsurface uncertainties affecting technical and commercial project robustness.
• Work with geologists, petrophysicists, geomodellers and reservoir engineers to assess risk and evaluate mitigation options.

Studies, Operations and Wells

• Coordinate geophysical and regional studies and integrate results into asset evaluations.
• Review operator geophysical input to integrated reservoir-modelling studies.
• Follow up and quality-control seismic acquisition and processing projects.
• Support appraisal and production well planning, including drilling targets and well-trajectory optimisation, and drilling operations.

Decision Support and Representation

• Provide recommendations documented by own analysis that support investment decisions.
• Represent OUN in license committees.
• Contribute to peer reviews and peer assists.

Qualifications

Education

• Master’s degree in Geophysics or relevant discipline is preferred

ORLEN Upstream Norway AS is an oil and gas company with its head office located in Stavanger, Norway. The sole owner is ORLEN S.A., which is the largest energy multi-utility in Central and Eastern Europe.

ORLEN Upstream Norway's key strategic goal is to supply gas to the ORLEN Group to meet growing market demand and bolster energy security in Central and Eastern Europe. We believe that this can be achieved through stable and diversified hydrocarbon production from the Norwegian Continental Shelf.

The company was established in 2007, and through a series of successful mergers and acquisitions, including INEOS E&P Norge, LOTOS E&P Norge, and KUFPEC Norway, it has grown into a recognized player on the Norwegian Continental Shelf. In 2025, the company ranked among the top ten largest hydrocarbon producers on the NCS. ORLEN Upstream Norway AS also has an extensive track record in exploration and is a partner in several key development projects, with Yggdrasil and Fenris being prime examples.

In 2024, the company’s name was changed from PGNiG Upstream Norway to ORLEN Upstream Norway to underline its affiliation with the ORLEN Group.

Currently, the company employs over 100 experienced professionals from all around the globe.
