Once the well is cased, holes called perforations are drilled around the bottom of the bore hole, which allow the oil to drain out of the surrounding rock formations and into the well. In a newly tapped reservoir, the high underground pressure will be enough to draw oil out and bring it to the surface, as it is literally pushed up to release in an area of lower pressure. This is the cause of the legendary geysers of oil at new oil wells.
