Drilling Rigs

A drilling rig is a machine that creates holes in the earth sub-surface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and are called augers. Drilling rigs can sample sub-surface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures (such as oil platforms, commonly called ‘offshore oil rigs’ even if they don’t contain a drilling rig). The term “rig” therefore generally refers to the complex of equipment that is used to penetrate the surface of the Earth’s crust.

Small to medium-sized drilling rigs are mobile, such as those used in mineral exploration drilling, blast-hole, water wells and environmental investigations. Larger rigs are capable of drilling through thousands of metres of the Earth’s crust, using large “mud pumps” to circulate drilling mud (slurry) through the drill bit and up the casing annulus, for cooling and removing the “cuttings” while a well is drilled. Hoists in the rig can lift hundreds of tons of pipe. Other equipment can force acid or sand into reservoirs to facilitate extraction of the oil or natural gas; and in remote locations there can be permanent living accommodation and catering for crews (which may be more than a hundred). Marine rigs may operate thousands of miles distant from the supply base with infrequent crew rotation or cycle.

Oil and natural gas drilling rigs are used not only to identify geologic reservoirs but also to create holes that allow the extraction of oil or natural gas from those reservoirs. Primarily in onshore oil and gas fields once a well has been drilled, the drilling rig will be moved off of the well and a service rig (a smaller rig) that is purpose-built for completions will be moved on to the well to get the well on line.[1] This frees up the drilling rig to drill another hole and streamlines the operation as well as allowing for specialization of certain services, i.e., completions vs. drilling.

Onshore Drillings Rigs

Drilling rigs are a perfect blend of quality, modernity and versatility. Drilling rigs are highly competent and technology driven. Drilling Rigs can be also used for up gradation of the modern rigs. The highly modern structure of the Rigs and the Drilling tools can be transported to any environment from the dry deserts to the remotest areas of the world.

Drilling rigs have the following features that make them unique:                                   Onshore rig

• can easily be transported by air
• Land Drilling rigs can wheeled on the desert
• Land Drilling rigs can be taken to rough terrains
• Drilling rigs on Land can be worked over

Land drilling and operations concerning work over:
Drilling operations are same like that of offshore Drilling operations.

Onshore Drilling rig products:

• Modern land rigs 800HP- 3000HP
• Drilling rigs are very inexpensive and energy saving
• Drilling rigs mechanization and controls
• Drilling rigs AC and DC modular Draw works
• Drilling push and pull rigs

Power/ control products:

• Engines and generators
• Control systems of SCR
• Drive systems with AC Variable frequency
• Drilling with auto driller
• Drilling with mud monitoring apparatus
• Drilling and monitoring systems

Land drilling is simpler, for you can easily carry the Drilling tools from one place to another. Onshore installations can be easily assembled. You can also easily recover your invested money through Land drilling.
Onshore land drilling services very efficiently provides for construction of drilling rigs and work over services. Drilling services relating to onshore land drilling is very commonly found in parts of Russia, Uzbekistan, and Kazakhstan.
Onshore land drilling rigs includes functions like product manufacturing, examination, assessment of oil gasses and wells of different kinds. The wells can be vertical or horizontal ranging between 1200 meters to 5000 meters in depth.
In the Middle East, Onshore land Drilling provides versatile and high quality Drilling Rigs. Onshore land Drilling also helps to improve and modify the existing Rigs.

Onshore land drilling can be used for circulating mud to the wells. The process of land drilling performs a number of important functions. The significant functions performed are described below:

• The on shore land drilling rigs are very efficient in cleaning the bottom of the wells
• The onshore land drilling rigs help to cool down the drilling bit
• The task of lubricating the onshore land rigs are also performed by the drills
• The on shore land drilling rigs help to fuse the walls of the well-bore
• The onshore land drilling rigs also help to regulate the pressure of oil, gas and water

The process of drilling begins in the huge bit anchored to the drill collar and drill pipe. A new drill pipe is joined with the drill string, when the process of drilling reaches certain depth. The procedure is generally repeated until the desired results are reached. The well bore, which is cased using a steel casing, is penetrated into the well bore. The joint is then cemented to prevent any emission of fluids.

In the next stage a drill bit of lesser diameter is penetrated inside the well bore and the previous operations are repeated itself. With the advancement in the drilling procedure smaller drill bits are used and the case hole diameter also goes on decreasing. It is very important that the drilling bit is replaced by new drilling bits. This process involves the removal of the whole drill string.

A self induced drilling tender mounted on a drilling rig is capable of being transported from one place to another. This enables the ships which participate in the drilling process to act as drilling ships. The legs of the platform can be lowered and the platform can be allowed to function independently as drilling platform. If necessary the drilling rigs can be lifted up from the drilling platform and placed on the near by land operations. This helps to carry out the land drilling operations to take place.

Offshore Drilling Rigs

Drilling Tools

Drilling Equipment: drilling Descriptions

Drilling Rigs: Drilling rigs can be of various kinds like skid-mounted rigs (diesel electric AC/VFD or DC/SCR drive rigs); trailer-mounted. Drilling rigs of another kind are the truck-mounted rigs (range from 450 HP to 1,000 HP).

Useful drilling components for drilling:

Drilling Equipment Rig Components: Equipment for specific extraction purposes comprise of both onshore and offshore Workover rigs ranging anywhere from 150 HP to 1,000 HP. Equipment other than this that go with are the diesel engines and the transmission sets and the minimum depth of the rig has to be 8,000 ft to 30,000 ft.

Oilfield drilling tools needed for drilling: the tools are varied and immensely useful.
Oilfield Solids Control Devices: Drilling equipments of this kind are a combination of,

Indispensable drilling devices:

• Oilfield shakers
• Oilfield desanders
• Centrifuges
• Oilfield degassers
• Oilfield agitators
• Desilters
• Mud cleaners
• Gas-liquid separators
• Sand pumps
• Shearing pumps

Oilfield extraction procedures involve all of these and it is necessary for the equipments to be of quality.
