A geoscientist is involved in the discovery, exploration and development of natural resources such as gas, oil and water.
They interpret geophysical, geochemical and geological data to develop models of the subsurface of the earth, with the aim of discovering commercially viable and exploitable reserves of natural resources, such as oil and gas.
Geoscientists provide the foundation for the exploration and production of natural resources. They are also involved in the production of reserves and may provide specialist advice for engineering projects.
Geoscientists work in a variety of roles within the natural resources sector. Job titles such as geophysicist, geologist, geochemist and sedimentologist are also used for specialist roles within geoscience
The tasks carried out by geoscientists vary depending on the specific area in which they work. In general, they can include:
Geoscientists working in exploration deal with a larger number of sites and a wide spread of data and also use satellite imagery and gravity and magnetic surveys to evaluate a whole basin. In production, geoscientists concentrate on sites that are already operational, making assessments on the basis of well core and well fluid samples.
As oil resources decline, the role of the geoscientist will change from exploration-dominated to production-dominated employment.
