What type of rig machine is used for drilling

There are several types of drilling rigs used for different drilling applications. The selection of a drilling rig depends on factors such as the depth of the target formation, the type of substrate being drilled, and the specific requirements of the drilling operation. 

Here are some common types of drilling rigs:

a) Land drilling rigs: These rigs are used for land drilling and are usually installed on platforms or frames. They can be further classified as:

-Mechanical drilling machines: These drilling machines use a rotary table to rotate the drill string and drill bit.

-Electric drilling rigs: These rigs are powered by electricity and use electric motors for drilling operations.

-Hydraulic drilling machines: These drilling machines use hydraulic power systems to drive the drilling process.

b) Offshore drilling rigs: These rigs are specifically designed for drilling in marine environments. They can be further classified as:

-Self elevating drilling machines: These drilling machines are movable and can be lifted above the water surface with retractable legs.

-Semi submersible drilling machines: These drilling machines float on the water surface, but can be partially submerged for stability.

-Drilling vessels: These are self-propelled vessels equipped with drilling equipment.
