The American Petroleum Institute (API) and the International Organization for Standardization (ISO) have established two basic types of pipes used for exploration and production in the oil and gas industry: casing and tubing. Casing and Tubing also known as OCTG. Casing and tubing strings are the main parts of the well construction. All wells drilled for the purpose of oil or gas production (or injecting materials into underground formations) must be cased with material with sufficient strength and functionality. Well casing  pipe is a pipe used in oil, gas, or water wells to protect the well walls and stabilize the wellbore.Casing pipe is used to line the drilled borehole that is being utilized for oil extraction. Similar to drill pipes, oil well casing pipe  is also subjected to axial tension and therefore needs to be made from high-quality, strong steel. Casing (well  pipe casing) is a large-diameter pipe fixed in the borehole using cement.Tubing is the pipe used after drilling is completed to transport crude oil and natural gas from the oil or gas reservoir to the surface. <\/span><\/p>\n

Types of Casing and Tubing<\/h2>\n
\n

Casing pipes are steel pipes used to support oil and gas wells, ensuring normal operation during drilling and after well completion. Each well requires multiple layers of casing depending on the drilling depth and geological conditions. Once the casing is lowered into the well, it must be cemented in place. Unlike tubing and <\/span>drill pipes<\/span><\/a>, casings are not reusable and are considered consumable materials. Consequently, casings account for more than 70% of the total consumption of an oil well. Casing types include seamless casing <\/span>pipe<\/span>(small and medium diameters), ERW casing <\/span>pipe<\/span> (medium diameter), casing <\/span>pup<\/span> joints, and casing couplings. Based on their purpose, casings are categorized as conductor casing <\/span>pipe<\/span>, surface casing <\/span>pipe<\/span>, intermediate casing <\/span>pipe<\/span>, and production casing <\/span>pipe<\/span>.<\/span><\/p>\n

\n<\/p>

Oil well pipe<\/span> casing pipe<\/span>s are further classified as follows:<\/p>\n

Conductor Casing pipe<\/span>: The first barrier between the surface and the underground. It helps prevent well collapse and groundwater contamination, and most importantly, provides structural support. Conductor casings are installed at the surface by drilling or driving. Their sizes range from 18 to 36 inches.<\/p>\n

Surface Casing pipe<\/span>: Primarily used for environmental protection and safety. It helps isolate freshwater zones, prevent blowouts, and supports the wellhead and blowout preventer (BOP) equipment. Therefore, surface casings must meet very high safety standards. They support the next casing string. The size can vary depending on the application, but the most common surface casing size is 13 3\/8 inches.<\/p>\n

Intermediate Casing pipe<\/span>: Not required for all types of oil and gas production. If used, it is placed between the surface casing and the production casing. Sizes range from 13 3\/8 to 16 inches.<\/p>\n

Production Casing pipe<\/span>: Provides structural integrity and pressure control for the hydrocarbon-bearing sections, mainly used during oil production.<\/p>\n

Production Liner: Can be hung from the production casing pipe<\/span> or one of the previous casing pipe<\/span>s. Liners help significantly reduce costs as they do not need to extend the entire depth of the well. They can be pre-perforated to save time and costs.<\/p>\n

Application of Casing and Tubing<\/h2>\n
\n

Casing and tubing are essential oil drilling equipment with various functions such as sealing perforations, supporting wellbore walls, preventing formation collapse, and controlling well flow. Casing and tubing are widely used in petroleum exploration, extraction, and transportation. During the exploration phase, casing and tubing are used to obtain geological samples and assess the properties of underground oil reservoirs. In the extraction phase, casing supports the wellbore walls, prevents wellbore collapse, and controls well flow. In the transportation phase, tubing is used to transport oil and natural gas.<\/p>\n

\n<\/p>

Well  pipe casing is subject to external pressure from the surrounding rock and internal pressure during oil production, so it needs to withstand high axial tension. During the drilling process, good well  pipe casing is very useful in the following aspects:
Fixes the drill string to prevent the collapse of unstable upper formations
Helps prevent contamination of the well area
Provides a uniform inner hole for easy installation of production equipment
Helps prevent contamination of the production area
Helps prevent liquid (oil) loss
Helps isolate the high-pressure area from the surface<\/p>\n<\/div>\n<\/div>\n

What is casing pipe ?<\/h2>\n
\n
Casing  pipe is a series of steel pipes that are inserted into a drilled well to stabilize the well, prevent contaminants and water from entering the oil flow, and prevent oil from seeping into the groundwater. Casing  pipe is installed in layers with decreasing diameters and connected together to form a casing string. There are five types of casing strings: conductor, surface casing, intermediate casing, casing liner, and production casing. Steel casing pipe has a smooth wall and a minimum yield strength of 35,000 psi.Casing is used for lining the complete borehole which has been dug into the ground to procure oil.  Casing is large diameter pipe which is held in place in the borehole using cement. The diameters of casing pipe range from 4.5\u2033 to 36\u2033.<\/div>\n<\/div>\n<\/div>\n
\n

What is tubing pipe ?<\/h2>\n
\n
Tubing pipe is inserted inside the wellbore through the oil well casing pipe, which helps the transportation of the hydrocarbons to the surface. It is pipe either used for transporting natural gas or crude oil to the facilities for further processing after the drilling is complete. Tubing is available in various sizes ranging from \u00be\u201d to 4 \u00bd\u201d.Tubing pipe is the pipe that carries oil and gas from the producing formation to the on-site surface facilities for processing. Tubing must be strong enough to resist the loads and deformations associated with production and well repair. In addition, the size of the tubing must be able to support the expected oil and gas production rate. Obviously, tubing that is too small will limit production and the subsequent economic performance of the well. However, tubing that is too large can have economic impacts beyond the cost of the tubing string itself, because tubing size affects the overall casing design of the well.<\/div>\n<\/div>\n<\/div>\n
