Geoscientist Reservoir Intern

Viridien (www.viridiengroup.com) is an advanced technology, digital and Earth data company that pushes the boundaries of science for a more prosperous and sustainable future. With our ingenuity, drive and deep curiosity we discover new insights, innovations, and solutions that efficiently and responsibly resolve complex natural resource, digital, energy transition and infrastructure challenges.

Job Summary

We are looking for a final-year Master’s student with a strong background in Geosciences, Physics or Mathematics.

During this six-month internship, you will join the Geoscience team and work alongside R&D teams to evaluate and enhance new seismic-inversion-related tools they are developing, with the ultimate goal of deploying those tools on real client projects.

You will work with HPC clusters, cloud-based processing pipelines and advanced visualization tools, and gain hands-on exposure to emerging machine-learning workflows for fault detection, facies classification and uncertainty quantification, developed in partnership with Viridien’s R&D labs. Within a small, collaborative team that shares knowledge through daily stand-ups and cross-team workshops with imaging and R&D, you will see your work have a real impact on client projects.

About the Team

The Geoscience team is a core part of the Imaging Department at Viridien.

We are a focused squad of five geoscientists and one petrophysicist located in Massy, France. Our primary goal is to deliver high‑quality 3‑D subsurface models that help our clients de‑risk exploration and production of energy resources. By integrating seismic, well‑log and geological data into reliable subsurface rock properties models, we give upstream teams the confidence they need to make informed decisions.

The team sits within the Imaging Department, so we work hand‑in‑hand with the processing groups to ensure the seismic images they produce are geologically faithful and ready for integration into our models. This tight collaboration keeps the workflow from raw acquisition to final interpretation smooth and science‑driven.

You will play a pivotal role in turning cutting‑edge research into everyday practice, helping the team deliver faster, more accurate subsurface models while staying at the technological leading edge.

Key Responsibilities

Characterizing the subsurface for resource recovery has been refined over decades, and new technologies are now essential to speed up the integration of seismic data into reservoir models. They rely on precise 3D modelling, advanced seismic imaging and high-quality well data. Our R&D group continuously develops innovative tools that keep our team at the forefront of technology and improve efficiency.

As an intern you will be the primary tester and bridge between R&D and the Geoscience team. Your day‑to‑day duties will include:

• Testing new R&D tools – Run the latest seismic‑inversion-related tools on real seismic and well datasets.
• Bug tracking & reporting – Document any unexpected behaviour, performance issues or usability problems, providing clear reproducible steps and screenshots.
• Suggesting improvements – Analyse test results, propose concrete enhancements (e.g., parameter tuning, UI tweaks, additional output options) and discuss them with the developers.
• Validating on production‑scale data – Apply the tools to large seismic volumes to verify robustness, scalability and the quality of the final geological interpretation.
• Daily collaboration with R&D – Attend joint stand‑ups, share progress updates, and participate to demo sessions to keep both sides aligned.
• Acting as the liaison – Translate the practical needs of the Geoscience team into technical requirements for R&D, and conversely convey R&D road‑maps and limitations back to the team.
• Documentation & knowledge transfer – Draft short user guides, best‑practice notes and internal training material so that the wider team can adopt the new tools quickly.
• Contributing to client deliverables – When a tool reaches production readiness, assist in integrating it into real client projects and help prepare the results for delivery.

Qualifications:

Required:

• Last year of Master degree in any of the following disciplines: Geophysics, Mathematics, Physics, Natural Sciences with a Physics specialization.
• Analytical approach to problem solving
• Enthusiastic attitude towards learning and passion for your subject
• The technical agility to adapt your existing knowledge to a new field
• Ability to effectively communicate technical concepts
• Evidence of leadership, teamwork or customer service either from involvement in university societies/extracurricular activities, volunteering and/or work experience/internships.
• Fluent English (read, written, spoken)

Preferred :

• Background in Geology
• Knowledge of well datas
• Knowledge in Geophysics
• 3D Modelling skills

Benefits:

• An international culture in which the well-being and development of our employees are a top priority
• Access to company restaurant with subsidized price
• Access to benefits from Company works council
• Reimbursement of 50% of public transportation card in Ile-de-France region
• Attractive sustainable mobility incentive
• Love sports? Access to equipped Gym with reasonable price. 
• Confidential employee assistance program to support our staff covering counselling, wellbeing, legal & financial issues.
