Oil well - Wikipedia

The well is created by drilling a hole 12 cm to 1 meter (5 in to 40 in) in diameter into the earth with a drilling rig that rotates a drill string with a bit attached. After the hole is drilled, sections of steel pipe (), slightly smaller in diameter than the borehole, are placed in the hole.Cement may be placed between the outside of the casing and the borehole known as the annulus.
