Casing pipe application in high-temperature gas wells

In recent years, with the decreasing number of easily exploitable oil and gas wells, it has become necessary for oil and gas wells to go deeper on both underground and underwater. And, tubing and casing strings are subjected to higher temperature and higher pressure in these wells, which would probably cause casing failure or gas leakage in the high-pressure/high-temperature (HPHT) wells. Hence, more attention has been paid to wellbore integrity in oil and gas industry in recent years.1,2 The key factor of wellbore integrity is casing string connections, which are expected to provide both structural and leakage integrity under severe environment.

What is the difference between casing pipe and well screen pipe?

Casing pipe definition: Casing is a series of steel pipes that are run into a drilled oil well to stabilize the well, keep contaminants and water out of the oil stream, and prevent oil from leaching into the groundwater. Casing is installed in layers, in sections of decreasing diameter that are joined together to form casing strings. The five types of casing string are conductor casing, surface casing, intermediate casing, casing liner, and production casing. casing pipe: The outer tubes are called casing. Casing lines the wellbore and thus protects the layers of soil and above all the groundwater from being […]

How does the casing pipe work ? Choose your casing tubing !

Once a well has been drilled, if it is to become a production well, the well must undergo completion. While drilling a well cuts through the rock formations and allows drilling engineers to reach the reservoir below, the raw sides of the well cannot support themselves. Similar to the bones of your spine protecting the spinal cord, casing is tubing that is set inside the drilled well to protect and support the ABTER STEEL. You can choose the oil casing to use, select the casing size range as follows: Standard: API 5CT Steel Grade: J55, K55, N80, L80, C90, T95, P110, Q125, V150 Dimension: 4 1/2″–20″ Connection: BTC, STC, LTC * P – […]

Performing Casing and Tubing Design

Info Needed for Casing Design • Mud weights • Formation pressures • Frack gradients • Casing seats • Casing sizes • Directional plans • Cement program • Temperature profiles • Base frack fluid, proppant type, and max proppant concentration • Max anticipated frack surface pressure • Produced fluid composition Casing Specifications & Benefits Casing can represent a big percentage of the overall well cost. This makes material grade, size, and connector selection not only an engineering consideration, but an economic one as well. Casing pipe is available in large diameters that are designed aid the borehole in withstanding forces and […]

API 5DP oil casing and tubing water well drill pipe

Casing: Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore.It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place. Tubing: Tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete.Tubing is manufactured in the same way as casing, except that an additional process known as “upsetting” is applied […]
