If you are into drilling, you know that there are many different types of drilling rigs used in the industry, depending on the specific needs of a drilling project. Drilling rigs Australia are no different. Here are the most common types of drill rigs on the market today:
Land Based Drilling Rigs
The most common type of drill rig used for exploration is the land-based drilling rig. Land-based drilling rigs are now smaller and more efficient than the rigs used in the past years. You’ll find land-based drilling rigs that are small, mobile, and very easy to move around, while others are gigantic and stationary.
Slim Hole Drilling Rig
While traditional drill bore is about 18 inches in diameter, a slim-hole bore can be as little as 6 inches only in diameter. The size of the drill site of slim-hole drilling rigs can be 75 percent smaller than a typically drill site. Thus, this type of drill rig requires less space than traditional drill rigs. However, this type of drilling equipment is not applicable in all environments.
Coiled Tubing Drill Rig
The coiled tubing drill rig can replace the typical drill string used in traditional drilling. Coiled tubing technology has a pipe with a continuous length, which is stored on a large spool. This technology reduces drilling waste and minimizes equipment footprints. Thus, you’ll find them usually used in environmentally sensitive areas.
Jack-up Drill Rigs
The jack-up drill rigs are typically used in relatively shallow water for off-shore drilling, with depths of approximately less than 300 feet. A jack-up drilling rig is a floating barge that houses the drilling structure. It has long support legs you can raise or lower onto the seafloor. These drill rigs are extremely strong, which are able withstand ocean storms and huge waves. Since the legs can be moved up and down easily, these drilling rigs are cost-effective and can be easily moved out during storms.
Semi-Submersible Drill Rigs
These type of drilling rigs are floating vessels that are supported on large structures, which are submerged below the surface of the sea. Semi-submersible are offshore drill rigs that has an advantageous design, submerging most of its components. This minimizes the load from waves and wind. Semi-submersibles can be used for different depths of water, even very deep ones. You can have these drilling rigs attached to the ocean floor with the use of strong chains and wire cables. Semi-submersibles also has dynamic positioning technology that enables the equipment to remain steady and immobile during drilling operations without the need for anchors.
Drill ships are also popularly used for exploration targets that are farther offshore. These rigs are specifically designed to be mounted on ships, which can drill a well in water depths of up to 10,000 feet deep. These rigs float just like a ship and can be attached to the bottom of the ocean using traditional anchoring systems. Similar to the semi-submersibles, you may also utilize its dynamic positioning technology so it remains stationary while drilling without using traditional anchors.
