Geosciences and Reservoir


Our expertise is multi-disciplinary and spans the entire chain, from data acquisition to synthesis, including information processing, data management, interpretation and integration.

  • Geologists
  • Geophysicists
  • Petrophysicists
  • Geotechnicians
  • Geochemists
  • Reservoir engineers
  • Hydrologists / Hydrogeologists
  • Environmental engineers
  • Geomatics professionals / Topographers


Geologists conduct subsurface studies using field data (outcrops, surveys, cores, logs, seismic data). Digital tools are increasingly used to create subsurface models, synthetize results and interact with other disciplines (drilling, reservoir engineering, hydrogeology). Geologists are involved in all areas related to geo-resources, and knowledge and protection of the subsurface.




Geophysicists use non-destructive investigation methods to obtain images of the subsurface. Depending on the depth of the objective, the desired resolution and the imaging target, they select the appropriate method, define the acquisition and processing strategy, and produce an interpretation.




Petrophysicists are specialists in determining the physical properties of rocks based on cores and logs. In particular, they calculate porosities, permeabilities, saturations and identify the type of fluids in place. As specialists, they mainly deal with geological reservoirs (fossil fuels and storage, deep geothermal energy).




Geotechnicians determine the behavioural properties of rocks by using field measurements (geotechnical drilling and sampling, pressuremeter tests, penetrometer tests, compaction) or by conducting various laboratory experiments on samples (creep, resistance to stress…). Their work helps improve the understanding of the near-surface subsoil, mainly in the areas of buildings, infrastructures, the environment and natural hazards.




Geochemists collect, analyze and interpret the nature and distribution of chemical elements in soils, rocks and fluids. They can trace the origin, age and history of minerals (mineral geochemistry) and/or those of hydrocarbons and water (organic geochemistry). Geochemists are especially in demand in the areas of fossil fuels, deep geothermal energy, water resources and environmental studies.



Reservoir engineers

Reservoir engineers study the dynamic behaviour of reservoirs (oil and gas bearing, storage, geothermal) using simulations and interpreting and integrating production data. They are involved in reservoir exploitation activities: development planning, monitoring, production forecasting and optimization.



Hydrologists / Hydrogeologists

Hydrogeologists study groundwater, in particular aquifers, from a static point of view (reservoir formation) as well as a dynamic point of view. They interpret well data (characteristics of the water, pumping tests) and simulate flow. They are involved in quantifying, producing and protecting water resources. In the case of aquifer storage or deep geothermal projects, their activities are close to those of a reservoir engineer. Hydrologists study surface water. They observe and measure precipitation, river flows, water runoff, infiltration and evaporation, and the impact of anthropogenic activities. They are involved in the areas of planning, natural hazards and the environment.



Environmental engineers

Environmental engineers predict and measure the environmental impact of development. They propose preventive or curative solutions to control pollution, reduce noise pollution and manage waste. Those solutions are defined in accordance with regulations and must be compatible with urban and industrial planning. Environmental engineers thus also act as an interface between companies, local authorities, government agencies, associations and regional Directorates of Ministries. Environmental engineers are consequently involved in all areas affected by sustainable development and they assist all industrial development projects.



Geomatics professionals / Topographers

Geomatics is a discipline incorporating geography and computer science. Geomatics professionals deal with geolocation data. They are involved in the fields of remote sensing and geographic information systems (GIS). They are familiar with the different projection systems and can align geographic data to produce intelligent maps that are used for results synthesis, communication and decision-making. Geomatics professionals can have a dual expertise (e.g. geology and geomatics), which allows them to examine critically the data they manage. Topographers handle terrain topographical data, mainly to create maps and feed GIS (Geographic Information Systems). The fields of applications are very varied: urban planning, environment, transport, energy, sustainable development, marketing, health, etc.

HSE site coordinators

HSE site coordinators coordinate the safety of site workers during construction and during later interventions. They provide coordination during design (risks identification, description of means to prevent accidents) and execution.



HSE engineers/managers

HSE managers must identify, assess and manage all occupational risks: working conditions, safety of assets and people, environmental protection. In order to reduce and control all those risks, they launch some prevention activities (fire drills, equipment checks), controls (compliance with safety standards), studies and other diagnoses (to assess and predict risks). They can also establish an Occupational Safety and Health (OSH) management system in accordance with ISO standards (IS09001/ISO14001/ISO18001/CEFRI/MASE).



Assistants to the HSE engineer/manager

Assistants to the HSE manager roll out and run risk prevention policies. They examine work positions, organize safety visits, monitor the fire safety records, ensure the management of waste, and provide advice on the storage and handling of hazardous products.



HSE technicians

HSE technicians implement risk prevention actions. They follow up on tests, checks and controls that are due in accordance with health and safety rules. They take measurements and samples in the work environment, ensure that the occupational health and safety registers are kept up to date, organize the procurement of chemical products, supply, control and hand out personal protective equipment (PPE). They are involved in and/or coordinate responses to accidents or fire.



HSE auditors

HSE auditors reporting to HSE managers carry out audits and diagnoses in offices, for projects, on sites, at subcontractors. They verify that the systems are compliant with the clients’ contractual requirements or with specific references. They check the application of operating procedures and instructions, assess the existing structures and suggest some improvements.



HSE instructors

HSE instructors provide ad hoc training and awareness programs on any HSE topic for company staff.
