Oil discovery refers to the process of finding new deposits of crude oil beneath the Earth's surface. This is typically done through geological surveys, seismic studies, and exploratory drilling. When a potential oil reservoir is identified, companies conduct tests to determine the quantity and quality of the oil present. Once a significant oil deposit is confirmed, it can lead to the development of oil fields, where extraction and production take place. The discovery of oil can have substantial economic impacts, influencing local economies and global markets, as oil is a critical energy source and raw material for various industries.
