UPSTREAM SECTOR
The upstream sector of the oil and gas industry involves processes including the searching for and the recovery of crude oil as well as its production. In the upstream sector, discovery or exploration of crude oil takes place. This involves intensive and extensive efforts towards ascertaining the actual places where crude oil is located.
Exploration is a very difficult process and therefore requires the service of experts in the field. More so, information technology plays active roles in the exploration or searching of crude oil in order to easily discover new grounds where oil is located and therefore take advantage of them.
The upstream sector includes different operations such as the searching for prospective underwater oil and gas fields, drilling of exploratory wells and also making requisite operations on the well so as to bring the crude oil or natural gas to the ground surface.
