Definition - What does Rig Equipment mean?
Rig Equipment is the devices or tools installed on a rig to perform various functions in the process of extraction and production of oil and gas. The type and functions of the equipment depend on the size and type of the rigs. Drilling rigs are of three sizes: the singles, the doubles and the triples. These categories state the length of the pipes that can stand in the derrick of the rig. Single holds one length pipes, double holds two and the triple holds three.

- Mud Pumps - These are reciprocal pumps that circulate drilling fluids throughout the system.
- Mud Motor - This is a hydraulic-powered device that spins the bit separately from rest of the drill string.
- Mud Tanks - These are the reserve stores for drilling fluid till it is taken down to the wellbore.
- Shale Shaker - This is a device used to separate drill cuttings from the drilling fluid before pumping it back to the wellbore.
