What is a drilling rig?
A drilling rig is a machine designed to dig holes in the ground, such as a borehole. The common conception of a drilling rig is for oil exploration, actually, the drilling rig is used for a wide variety of purposes, from oil and gas to water well drilling, mineral exploration, and geological study. The size of a drilling rig greatly differs based on the needs, a portable drilling rig can be transported by truck to massive structures designed to penetrate deep into the ground.
How does a drilling rig drill into the ground?
Various methods for drilling deep underground or exploring what’s under it with drilling rigs.

What is the feature of a drilling rig?
A portable drilling rig for water well drilling is showing differences in drilling rig machine design. Small units mounted on caterpillar treads that drill up to 200m and large scale drilling rigs that can drill down to 800m in depth. These smaller scale drilling rigs are usually equipped with hydraulic legs, which is a portable folding system allowing the user to place the rig quickly at various locations.
What is the price of a drilling rig?
The price of a drilling rig is different according to the requirements, such as the depth of the borehole, and the diameter of the borehole. Also, the types of drilling rigs are very important to the price too, such as the hydraulic drilling rig, crawler drilling rig, etc. Will you prefer to drill with compressed air or a mud pump?
