FAQS about Drilling rig definition dictionary

What is a drilling rig?

Collins English Dictionary. Copyright © HarperCollins Publishers A drilling rig is the equipment used to drill a wellbore. Major components of the drilling rig include the mud tanks and pumps, the derrick, the drawworks, the rotary table, the drill string, the power generation equipment and auxiliary equipment.

What are the components of a drilling rig?

Major components of the drilling rig include the mud tanks and pumps, the derrick, the drawworks, the rotary table, the drill string, the power generation equipment and auxiliary equipment. A complete drilling rig may be assembled on a barge and the vessel used for drilling wells in lakes and in inland waters and marshes.

What are oil and natural gas drilling rigs used for?

In the background are the Discoverer Enterprise, GSF Development Driller II, and Helix Producer I Oil and natural gas drilling rigs are used not only to identify geologic reservoirs, but also used to create holes that allow the extraction of oil or natural gas from those reservoirs.

What type of drilling rig is used in underground mining?

Underground mining (hard rock) uses a variety of drill rigs dependent on the desired purpose, such as production, bolting, cabling, and tunnelling. In early oil exploration, drilling rigs were semi-permanent in nature and the derricks were often built on site and left in place after the completion of the well.

What is a small mobile drilling rig?

Small mobile drilling rigs are also used to drill or bore piles. Rigs can range from 100 short tons (91,000 kg) continuous flight auger (CFA) rigs to small air powered rigs used to drill holes in quarries, etc. These rigs use the same technology and equipment as the oil drilling rigs, just on a smaller scale.

What are mining drilling rigs used for?

Mining drilling rigs are used for two main purposes, exploration drilling which aims to identify the location and quality of a mineral, and production drilling, used in the production-cycle for mining.

Mud circulation drilling rig

This is the tank from which drilling fluid is pumped downhole and to which drilling fluid returns from the hole is received. The route taken by the drilling fluid when circulating is called the active (circulating) system. At the start of circulation, the Mud Pumps are lined up on the Active Tank, and drilling fluid is pumped to. . These are used for storing fluids according to requirements. Reserve mud is usually prepared or stored in these tanks or different fluids in preparation for. . The Sand Traps are usually positioned below the shale shakers and act as settling pits for the drilling fluid after passing through the shale shakers. The. . These tanks are more minor than active and reserve tanks. They are used for preparing “slugs” (high-density mud that is pumped into the drill string before tripping out of the hole) and pills to address particular situations (e.g. an LCM pill to control formation losses, a unique mix to improve drilling mud properties, etc.). . The Trip Tank is a tall, narrow tank located near the flow line and used for accurately monitoring drill pipe displacement volumes while tripping pipe in or out of the hole. Active drilling mud from the Trip Tank is circulated across the hole, and valves in the flow line near the Bell Nipple are realigned to send the fluid returns back to the Trip . [pdf]
