An automated drill rig (ADR) is an automated full-sized walking land-based drill rig that drills long lateral sections in horizontal wells for the oil and gas industry. [8] ADRs are agile rigs that can move from pad to pad to new well sites faster than other full-sized drilling rigs. Each rig costs about $25 million.
Big Stan was designed as a vehicle mounted drill rig that is normally mounted on a 40 feet (12 m) long, 5-axle truck, but is also compatible with a specially designed continuous track-style carrier. [1] When made fully operational, the top of the drill (the boom arm) can extend to 93 feet (28 m) in height when leveled with the ground.
Drill bit (#26) is a device attached to the end of the drill string that breaks apart the rock being drilled. It contains jets through which the drilling fluid exits. Drill floor (#21) is the area on the rig where the tools are located to make the connections of the drill pipe, bottom hole assembly, tools and bit. It is considered the main area ...
This truck was not a success; however, Unit Rig went on to be a very successful maker of off-highway dump trucks sold under the brand name of Lectra Haul (due to their electric drive system). In the 1970s, a large order for M200 trucks was received, to be shipped to the USSR. At that time, the US government did not allow trade with the Soviet ...
In 1994, Rowan (now Valaris Limited), which had used the company to manufacture its drilling rigs, acquired the company from General Cable for $50 million. [4] [5] In 2011, Rowan (now Valaris Limited) sold LeTourneau Technologies to Joy Global. [6] Joy Global subsequently sold LeTourneau's Drilling, Marine, and Power divisions to Cameron ...
Wireline truck rigged up to a drilling rig in Canada. In the oil and gas industry, the term wireline usually refers to the use of multi-conductor, single conductor or slickline cable, or "wireline", as a conveyance for the acquisition of subsurface petrophysical and geophysical data and the delivery of well construction services such as pipe recovery, perforating, plug setting and well ...
A rotary table is a mechanical device on a drilling rig that provides clockwise (as viewed from above) rotational force to the drill string to facilitate the process of drilling a borehole. Rotary speed is the number of times the rotary table makes one full revolution in one minute (rpm).
[6] [7] By the first century BC, Chinese craftsmen cast iron drill bits and drillers were able to drill boreholes up to 1,500 metres (4,900 ft) deep. [8] [9] [10] By the eleventh century AD, the Chinese were able to drill boreholes up to 900 metres (3,000 ft) in depth. Drilling for boreholes was time-consuming and long.
