This article lists the main components of a petroleum onshore drilling rig. Offshore drilling rigs have similar elements, but are configured with a number of different drilling systems to suit drilling in the marine environment. The equipment associated with a rig is to some extent dependent on the type of rig but. .

Micropiles (mini piles, pin piles, needle piles, and root piles) are deep foundation elements constructed using high-strength, small-diameter steel casing and/or threaded bars. .
Micropiles (mini piles, pin piles, needle piles, and root piles) are deep foundation elements constructed using high-strength, small-diameter steel casing and/or threaded bars. .
The micropile casing generally has a diameter in the range of 3 to 10 inches. Typically, the casing is advanced to the design depth using a drilling technique. Reinforcing steel,. .
Comprehensive fleet of rigs and tooling for difficult subsurface conditions and limited access Alleviates quality assurance concerns associated with cast-in-place piling in weak soils Can be combined with other techniques to meet unique or complex project requirements cost-effectively and efficiently .
The finished micropile (mini pile) resists compressive, uplift/tension, and lateral loads and is typically load tested following ASTM D 1143 (compressive), ASTM D 3689 (uplift/tension), and ASTM D 3966 (lateral). Capacities vary depending on the micropile size and subsurface profile. Allowable compressive capacities of more than 500 tons have. These drills are primarily used to drill tie-backs using a high-powered percussion head. They can also be equipped to drill using cased methods as required. The units can be mounted on a variety of excavator carriers to suit individual project requirements.
[pdf] 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. .
The Rig, or Carrier, is a mobile truck with a derrick and a cab for one driver. The carrier can also be trailer-mounted, enabling it to be. .
The crew members on service rigs each have specialized experience and expertise. The entry-level workers are junior floor hands.
