The Drilling Rigt

Drilling rig is a building with equipment to drill into the underground reservoir for water, oil, or natural gas, or underground mineral deposits. Drilling rig can be on the ground (on shore) or on the sea / offshore (off shore) depending on the needs pemakaianya. Although offshore rig can drill down to the sea floor to search for minerals, technology and economics of underwater mines can not be done commercially. Therefore, the term "rig" refers to the collection of equipment used for drilling on the surface of the Earth's crust to sample the oil, water, or mineral.

Drilling rig for oil and gas can be used not only to identify the geological nature of the reservoir, but also to create a hole that allowed the womb making oil or gas from these reservoirs.

Drilling rig can be sized:

* Small and easy to move, as used in mineral exploration drilling
* Large, capable of drilling through thousands of feet into the Earth's crust. Large mud pump used to circulate drilling mud through the drill and casing (casing), to cool and take "the land that was interrupted" for wells drilled.

Pulley on the rig can lift hundreds of tons of pipe. Other equipment can encourage acid or sand into the reservoir to take samples and mineral oil; accommodation for the crew that could run into the hundreds. Offshore rig can operate hundreds to thousands of miles from shore.
