Geologists and Oil and Gas Investment Companies are responsible for the discovery of oil in different locations. They use various techniques to find out oil, as they study the location for conditions of which would indicate the occurrence of confined oil.

Finding the right source rock and typically the reservoir rock will guide straight to the presence of oil. Satellite images too are used in figuring out areas where oil can be present, in add-on to studying surface stones and terrains.
They use many techniques including the use of sensitive gravity meters, which indicate very little changes in the gravitational field of the planet, which could indicate typically the presence of flowing essential oil.

Seismology techniques too are used where shock dunes are passed through rock levels, and the reflected waves are studied to check for the presence of essential oil. Thus, once geologists make a discovery, preparations are produced to extract oil by means of drilling.
Before drilling regarding oil can commence, typically the site where drilling is to be carried away needs to be ready. These preparations include creating access roads to typically the location of drilling, plus getting a source of drinking water.
Just before the actual hole will be drilled, they dig a new cellar. This provides for a room for the workers to move around and also to set away from the equipment. This portion of the hole will be wider and shallower. After these preparations are full, the rig is brought in.
