Saudi Arabia holds the title as the world's largest producer and exporter of total petroleum liquids, and the country's national corporation, Saudi Aramco retains the most proven reserves and production of hydrocarbons worldwide. Only behind Russia as the largest crude oil producer, Saudi Arabia has an estimated 267 billion barrels of proven oil reserves, including 2.5 billion in the Saudi-Kuwaiti Neutral Zone, and 253 trillion cubic feet (Tcf) of proven natural gas reserves. Impressively, more than half of Saudi Arabia's oil reserves are sourced from only eight fields.
Geoscientist is a general term used to describe the individuals responsible for locating, evaluating and developing oil and gas reservoirs. Geoscience professionals use technology and applied science to maximize the recovery of oil and gas. They are present at all phases of the reservoir life cycle, from exploration, through drilling, production and eventually abandonment. They will measure and map seismic, magnetic, and other earth forces that affect the earth, as well as study and interpret data that is useful in locating oil and gas reservoirs. Geochemists, geologists, geophysicists, as well as geoscience technicians all fall into this category.
