Petroleum exploration is the process of searching for oil and natural gas deposits beneath the Earth's surface. This involves geological surveys, seismic studies, and drilling exploratory wells to assess the presence and quantity of hydrocarbons. Geologists and geophysicists analyze rock formations and other data to identify potential drilling sites. Once a promising site is found, companies may conduct further tests to evaluate the viability of extraction. Successful exploration can lead to the development of oil fields, contributing to energy production and economic growth. Key technologies used in this field include 3D seismic imaging and drilling rigs.
