Petropedia explains Power Rig

Drilling rigs are one of the most important tools 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. The massive structure rigs can be either onshore rigs or offshore rigs. Onshore rigs perform drilling activities on land, whereas offshore rigs perform drilling activities in sea or ocean.

Some of the types of drilling rigs used are as follows:

  • Land Rigs (onshore rigs)
  • Barge Rigs (operate in shallow water)
  • Jack up Rigs (operate in water at a depth of 500 ft)
  • Semi-Submersible Anchored / Moored Rigs (operate in water up to depths of 10,000 ft)
  • Dynamically positioned vessel for Deep or Ultra Deep Water drilling (up to 12,000 ft).
