Petropedia explains Truck-Mounted Rig
Drilling rigs are one of the most important machines in the E&P activities of the oil and gas industry. They can be massive or small to medium-sized structures. The small to medium-sized rigs are also called mobile rigs as they are mounted on trucks or trailers and can be easily transferred from one location to another. For different drilling operations various types of drilling rigs are needed. These rigs are used for onshore drilling operations only and function in a similar way as the high capacity rigs; however, the power output of such rigs is small and are used for low depth drilling operations.
