Drilling rig is a machine to drill holes in the ground. It is also known as diamond core rig in general place. It is mainly used to the on-shore or off-shore oil well, water well or the exploration of natural gas. With concern to its structure, diamond core rig can be complicated and massive. It can also be light, small enough to be controlled only by one person. Drilling rig can be ported by mobile tools such as truck or trailer. Or it can be more permanent like the marine-based oil platform.
