All rotary tables feature a fabricated frame, heavy duty main thrust bearing and precision machined spiral bevel gear that results in superior strength, toughness and durability.

American Block can also provide unitized rotary table assemblies (IRD). Our unitized skid packages are ideal for new builds or can be retrofitted to existing rigs. Featuring a heavy-duty oilfield skid and an extend life transmission. The rugged design ensures that when the equipment is mounted it remains rigid during operation and rig moves. Other rotary table options include hydraulically operated tables and high torque tables (25% more torque), which are ideally suited for top drive operation.

A rotary table is a rotating apparatus used mostly in drilling rigs to deliver a clockwise rotational force to a drill string. This makes it useful in enabling the process of creating a borehole. Rotary speed is also referred to as the rounds per minute (rpm), which pertains to the number of rotations that can occur in one minute. Rotary tables are sometimes called, ‘turntables’ in the oil and gas drilling industry. They are provided by reputable companies specializing in fracking and mud pumps, such as Shale Pumps, and it is advisable that you work with such equipment providers, so you can get the best value for your money in drilling equipment.

The rotary table would typically use a chain-driven mechanism, similar to the chain assembly you would find on a bicycle. This chain needs to be lubricated frequently to prevent burning and seizing. Rotary tables typically have a rotary lock, which is present to keep it moving in a fixed direction. However, it can be unlocked to prevent restrictions, so you can move the rotary table in either direction.

At the center of rotary tables, you can find the bushings that can be removed in separate pieces, so bigger items, like drill bits, can pass through them. A large gap in the heart of the table is known as the ‘bowl’ due to its appearance and shape. Slips are applied in the bowl to keep the drill string in place during pipe trips and connections as the drill string goes through the wellbore. Bushings link to kelly bushings to initiate the spin to start drilling.

Modern drilling rigs may not have a rotary table anymore, as it has been replaced with high-end top-drive technology, in which the drill string turns due to the mechanism found on top of a string. The top drive is connected to the blocks, eliminating the need for a swivel, as all the important actions occur at the top drive. Despite this, kelly bushings and the kelly bar are still used.

Cameron rotary tables range from 27 1/2 in to 60 1/2 in and feature a large oil capacity that adds to the unit"s durability. The rotary table includes a forged-steel fabricated housing and a heat-treated forged-steel turntable. Each rotary table is supplied with spiral-bevel, induction-hardened gears and two independent ratchet-type locks, with lever access from the top to lock the table in position.

The rotary system on a drilling rig is the system that causes the drill bit rotate at the bottom of wellbore. We have discussed some components of the rotary system when we discussed rotary table and top-drive rigs, but we have not yet discussed the entire system.

A schematic of the rotary system is shown in Figure 9.07. As we can see in Figure 9.07, the rotary system shares many components with the circulation system. This is because in the rotary system, these components rotate in support of causing the bit to rotate, while in the circulation system, these components act as conduits for the drilling fluid.

In Lesson 8, we saw that the rotary table imparted the torque for the drill string in a conventional rotary table rig, while the top-drive imparted this torque on a top-drive rig. We also saw that drill pipe was added to the drill string one joint at a time on a rotatory table rig, while a top-drive could add multiple joints of drill pipe during one connection operation.

The Bottom-Hole Assembly is comprised of any bottom hole equipment required to drill the current section of the well. A bottom-hole assembly may be as simple as a Drilling Collar. Drill collars are sections of heavy, thick walled pipe used to add weight-on-bit to the drill string. More complicated bottom-hole assemblies may include Jars, downhole directional steering and positioning equipment, logging-while-drilling, and measure-while-drilling equipment.

At the end of the drill string and bottom-hole assembly is the drill bit. There are many types of drill bits, but we will focus on two types of drilling bits, the Tri-Cone (or Roller Cone) Bit and Fixed-Cutter Bit. In addition, we will be discussing two variants of the tri-cone bit: the milled-tooth bit and the insert bit. All of these bits can be classified as in the following bullet list:

Tri-cone bits are the most common drilling bits and, historically, have been the workhorse of the drilling industry. As the name implies, tri-cone bits contain three cones, each of which contain cutting teeth.

The two-cone bit (an early version of the tri-cone bit) was invented by Howard Hughes Jr.’s father (Howard Sr.). The tri-cone bit and the formation of the Hughes Tool Co. (now part of Baker-Hughes, a subsidiary of the General Electric Corporation) was the source of the Hughes family wealth. In case you do not know who Howard Hughes Jr. was, he was an award winning pilot in the 1920s and 1930s (holder of several aerial speed records and subject of the movie “The Aviator”), a filmmaker (had controlling interest of RKO Studios and actively produced several notable silent and early “talkie” films), airplane designer (owner of Hughes Aircraft – contractor for the world’s largest wooden airplane, “The Spruce Goose,” with Howard as its only pilot in 1947), and a billionaire by the 1970s and 1980s (back when a billion dollars had some value).

One design feature of the tri-cone bit is the interaction of the teeth on the different cones helping to remove any small cuttings or sticky shales/clays (Gumbo Shales) that may get lodged between the teeth and reduce the efficiency of the bit. This phenomenon of cuttings and clays getting lodged between bit teeth is referred to as Bit Balling and results in slower Rates-of-Penetration (ROP) of the drilling process. The self-cleaning action of the teeth in a tri-cone bit is designed to reduce the bit balling.

Milled-tooth tri-cone bits are mainly used for drilling through soft rock formations. This is because, no matter how strong the steel used in the construction of the cone, hard rock can cause excessive wear and degradation of the teeth.

While the insert bit helps to alleviate the issues with tooth-wear, there is an additional source of wear that can shorten the life of a drilling bit. Due to the moving parts associated with a tri-cone (or roller) bit, the bit requires a bearing where the moving parts meet and move past one another. Thus, the wear on the bearings may also shorten the life of the bit.

The PDC bits are used to drill through very hard rock formations or for extended bit-life drilling. These bits have a large initial cost but because of the hard teeth and lack of any moving parts have a longer bit-life. One recent innovation for PDC bits in geologic basins with many shallow (short-footage) drill sites is the ability to rent the drill bit from the drilling company rather than to purchase it from a tool company. This innovation allows for an operating company to rent the bit and to use it for the footage that they require before relinquishing it to another operating company.

We have discussed that the tri-cone bits and the fixed cutter bits have different drilling actions. Here is a YouTube video, "Drill Bits - Oil and Gas Drilling: From Planning to Production" (3:26), that demonstrates the differences of the explosive, gouging, and crushing action of the tri-cone bit and the scraping action of the fixed cutter bits:

While we"re out of the hole the operator also wants to switch to a track hone bit. This style of bid is less aggressive than a PDC and will drill a little slower. Bit selection is very important part of drilling a well so let"s go review that now.

Tungsten carbide insert, or TCI bits, have tungsten carbide treated inserts that gouge, chip, and crush rock. Tungsten carbide is one of the hardest materials known and TCI bits are capable of drilling some of the hardest and most abrasive formations. Tungsten carbide inserts come in a variety of shapes and because of their appearance TCI bits are often called button bits.

Polycrystalline diamond compact, or PDC bits, have tungsten carbide cutters topped with hard caps of diamond composite material. The cutters are angled and arranged to shear channels in the rock. The diamond caps are made by heating and compressing artificial diamond grit with tungsten carbide and other metallic binders. PDC bits come in a variety of designs that can be used for an extensive range of drilling requirements. PDC bits are much more expensive than roller cone bits but can generally penetrate faster and last longer than roller cone bits which saves drilling costs.

A kelly drive is a type of well drilling device on an oil or gas drilling rig that employs a section of pipe with a polygonal (three-, four-, six-, or eight-sided) or splined outer surface, which passes through the matching polygonal or splined kelly (mating) bushing and rotary table. This bushing is rotated via the rotary table and thus the pipe and the attached drill string turn while the polygonal pipe is free to slide vertically in the bushing as the bit digs the well deeper. When drilling, the drill bit is attached at the end of the drill string and thus the kelly drive provides the means to turn the bit (assuming that a downhole motor is not being used).

The kelly is the polygonal tubing and the kelly bushing is the mechanical device that turns the kelly when rotated by the rotary table. Together they are referred to as a kelly drive. The upper end of the kelly is screwed into the swivel, using a left-hand thread to preclude loosening from the right-hand torque applied below. The kelly typically is about 10 ft (3 m) longer than the drill pipe segments, thus leaving a portion of newly drilled hole open below the bit after a new length of pipe has been added ("making a connection") and the drill string has been lowered until the kelly bushing engages again in the rotary table.

The kelly hose is the flexible, high-pressure hose connected from the standpipe to a gooseneck pipe on a swivel above the kelly and allows the free vertical movement of the kelly while facilitating the flow of the drilling fluid down the drill string. It generally is of steel-reinforced rubber construction but also assemblies of Chiksan steel pipe and swivels are used.

The kelly is below the swivel. It is a pipe with either four or six flat sides. A rotary bushing fits around the flat sides to provide the torque needed to turn the kelly and the drill string. Rollers in the bushing permit the kelly free movement vertically while rotating. Since kelly threads would be difficult to replace, normally the lower end of the kelly has saver sub — or a short piece of pipe — that can be refurbished more cheaply than the kelly. Usually, a ball valve, called the lower kelly cock, is positioned between the kelly and the kelly saver sub. This valve is used for well control if the surface pressure becomes too high for the rotary hose or surface conditions.

According to the ″Dictionary of Petroleum Exploration, Drilling and Production″, ″[The] kelly was named after Michael J. (King) Kelly, a Chicago baseball player (1880-1887) who was known for his base running and long slides.″
