Drilling rigs are buildings that house equipment like pipes, cables, drill bits and derricks which are mandatory in extracting necessary commodities such as petroleum from under the earth’s surface. The rigs are categorized under offshore and land with the offshore dealing with drilling on the ocean floor and land based drills handling the drilling that is achieved on land.

Apart from extracting petroleum, they can be utilized within the development industry in building basis development, roadbed, bridges and airports constructions where robust foundations are required. They will also be utilized in mining, drilling and water well drilling. The drilling rigs come in different types and probably the most suitable is selected according to the task that is at hand. The drilling rig classifications will be achieved using varied factors, attributes or technologies.

By energy

The kind of power a drilling rig makes use of can decide what type it is. Usually, you can find mechanical drilling rigs which use clutches, transmissions and torque converters that are powered by their own diesel engines. The electric ones are those whose machinery items are driven using electric motors generating power on site through inner combustion engines. There are also hydraulic rigs which use hydraulic energy, steam rigs which use engines and pumps which are steam powered and the pneumatic ones which are powered utilizing pressurized air.

By Pipe

Rig categorization under pipe has cable drilling rigs that use cables to lift and drop drill bits, standard drilling rigs which use plastic or metal drill pipes of different types to suit the operate and col tubing rigs that use big tube coils and down hole drilling motors.

By height

Height categorization comes in when quickly removing drill pipes from the hole and relies on the number of related pipes within the derrick. Single rigs pull dingle drill pipes, whereas double rigs can deal with a stand of pipe that has two connected pipes within the derrick. Triple stand rigs can handle three whereas quadri stand can accommodate four connected drill pipes.

By drilling method

The drilling technology classifies the drilling rigs into non rotational rigs that embody most service rigs and direct push rigs. There are also rotary table rigs that achieve rotation by turning a hexagonal or sq. pipe on the floor level of the drill. High drive rigs have the circulation and rotation executed across the top space of drill string on motors moving on track alongside the equipment derrick whereas sonic rigs use vibratory energy so that the drill string is advanced. You will also discover hammer rigs that use percussive and rotation force.

By derrick position

Drilling rigs may also be categorized in response to the positioning of the derrick on the equipment. There are standard rigs that have the derrick in vertical position and slant rigs that have the derrick slanted at an angle of 25 degrees in order that horizontal drilling is facilitated.

Regardless of the drilling needs you’ve, there’s always an significance of making positive you choose the best for the task at hand. Once you know what your options are your possibilities of selecting one of the best drilling rig are increased.
