Service Rigs

A service rig is a mobile platform loaded with oil industry service equipment that can be driven long distances within the oil fields to service wells. Unlike drilling rigs, service rigs return to a particular well many times. There are several specialized types of service rigs: the carrier, the pumptruck, the doghouse, a 5 ton equipment truck and several crew vehicles.
