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.

XXXX Job Details

This internship is for physicists, mathematicians and geophysicists in their last year of school, who are looking for a six-month internship where they can put their theoretical knowledge and problem-solving skills to the test working on real Earth data.

We welcome all international students with valid work permit in France! Please note that follow French regulation, we will need to sign an internship agreement with your school. Please verify in advance if it's possible to obtain from your side the signature of your school for this agreement.

What will you learn?

The world beneath our feet is both incredibly complex and the source of natural resources fundamental to the functioning of our society. We use the latest signal processing, modelling and imaging techniques and are among the most advanced compute facilities in the world to build high-resolution 3D images and models of subsurface structure and rock properties for our clients. During your internship, you will be working inside a processing and imaging team, in close collaboration with our R&D department, in order to provide the latest available technology to our clients. You will have the opportunity to work on one of the following topics:

Land processing & Imaging:

• Organizing a large dataset - several hundred Terabytes per step of processing
• Testing and following a processing sequence of signal processing (denoising, designature, multiple suppression)
• Building a velocity model with the latest available technologies (full waveform inversion, tomography)
• Presenting status reports to the clients each week

Marine processing & Imaging:

• Testing and following a processing sequence of signal processing (denoising, designature, multiple suppression)
• Building a velocity model with the latest available technologies (full waveform inversion, tomography)
• Presenting status reports to the clients each week

4D processing & Imaging:

• Testing and following a sequence of signal processing designed to remove non-repeatable noise while preserving signal enabling to monitor reservoir evolution
• Imaging the various surveys in order to locate the 4D difference at its true geological location
• Running a preliminary analysis of the results to ensure the reservoir evolution (porosity, permeability) and possible subsidence effects have physical meaning
• Presenting status reports to the clients each week

Elastic FWI:

Full waveform inversion (FWI) is now the standard solution to build a velocity model either for land or marine data. However, most FWI run in the industry are performed using acoustic modeling due to the prohibitive cost of elastic modeling. At Viriden we are currently working on improving the efficiency of the elastic FWI for production, including large surveys. This will allow for the inversion of Vp, Vs and density which can be used by the reservoir department to derive rock properties such as porosity and permeability.

During this internship you will be in charge of:

• Testing elastic-FWI over several different real-world datasets to monitor the appropriate estimation of Vp, Vs and density parameters
• Verifying the quality of the results with our reservoir specialists
• Optimizing the use of these tools to make them cost effective in production.

Qualifications

• Last year of Master’s degree in any of the following disciplines: Geophysics, Mathematics, Physics, Astrophysics/Astronomy, Natural Sciences with a Physics specialization.
• Key Skills and Experiences 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.

Recruitment process:

1. Once your resume passes the screening round, you will be invited to a short-automated video interview.
2. Success at this stage is then followed by a competency skills-based HR interview.
3. Then a final-stage technical interview with some of our geophysical managers.
