Save to shortlist Saved to shortlist Apply now

CGG is a global geoscience technology leader and industry pioneer with a history of over 90 years of pushing the scientific boundaries of what is possible. Employing around 3,700 people worldwide, we provide a unique range of data, products, services and solutions to solve the complex natural resource, environmental and infrastructure challenges of our clients. CGG is listed on the Euronext Paris SA (ISIN: 0013181864).

This role 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. The role is based in Massy, a town in the greater Parisian region of France.

We welcome all international students with valid work permit in France!

What will you learn?

The world beneath our feet is both incredibly complex and the source of the natural resources fundamental to the functioning of our society. We use the latest signal processing, modelling and imaging techniques and 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: Within one of our teams dedicated to ultra-high density processing and imaging for land data, you will be in charge of:

  • 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: Within one of our teams dedicated to marine processing and imaging (streamer and/or OBN/OBC), you will be in charge of:

  • 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: Within one of our teams dedicated to processing and imaging of 4D monitoring data, you will be in charge of:

  • 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 CGG 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.

Carbon capture: CO2 storage is a crucial step towards carbon neutrality. Within this new field, CGG, a worldwide leader in subsurface imaging, has a critical role to play by providing clear images of the subsurface which can be used to assess potential reservoirs and monitor them during their lifetime. During this internship you will be in charge of:

  • Imaging seismic data in order better understand the reservoir structure
  • Deriving porosity and permeability variation inside the reservoir
  • Modelling and verifying decimation of acquisition to allow efficient and cost-effective monitoring of the field

Seismic imaging & Seismic reservoir characterization: During your internship, you will:

  • Be involved in the processing of seismic data
  • Integrate well data, seismic data and interpreted horizons into a database
  • Understand and analyze the seismic response of the reservoirs through seismic modeling (Well to Seismic tie, Avo response, …)
  • Monitor seismic processing and assess its impact on seismic reservoir response (Does it fit the established model?)

Qualifications

In the last year of Masters degree in any of the following disciplines: Geophysics, Mathematics, Physics, Astrophysics/Astronomy, Natural Sciences with a Physics specialisation.

What do we look for during the application process?

  • 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.

Benefits Package

  • Competitive salary
  • Highly attractive bonus scheme
  • Initially 22 days' holiday with future increases, complemented by a flexible buying and selling holiday program
  • Company contributory pension plan
  • Accommodation assistance programme
  • Flexible Private Medical & Dental care programs, tailored to suit individual or family needs
  • Employee Assistance Program to support our staff
