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.
Production engineers monitor and evaluate the production and efficiency of an oil or gas well. They develop methods to improve extraction, oversee drilling activities and will determine the need for new or improved tools. One of their main responsibilities is to evaluate the flow between the reservoir and the wellbore. Production engineers monitor the entire production process and will design completion systems and select equipment that will increase production rates. Production engineers are usually petroleum engineers, however sometimes an engineer from a different discipline will be trained on production engineering tasks.
