Tubing Spools to be an Essential Part for Wellhead Systems

Tubing spools are of major importance for the gas and oil field. Drilling of a well to generate oil and gas requires a spool wellhead structure during the complete procedure. This complete system involves several components other than tubing spools such as preliminary casing head, intermediate casing spools, slip casing hanger, seal, and other accessories essential to complete the wellhead system. The tubing spools wraps up the task with its lockdown feature.

The tubing spools are installed before the well is completed. It is used to avoid damages on sealing areas, due to drilling equipment, and to wedge the tubing hangers, bowl protectors, and test plugs. Furthermore, the tubing spools having two flanges are attached to the casing spool that is used to dangle the smallest casing string and seal the annular space between the casing and tubing.

The procedure begins with the preliminary casing head, that has to be attached to the surface casing of the conductor. After this, the intermediate casing spool is used to access annulus. An intermediate casing spool is a flanged-on-flanged pressure container that is installed after an additional casing has been to a course. The lower section of the intermediate casing spool closes the external diameter of the lastly installed casing string. It is arranged in such an order that the lower flange gets coupled with the preliminary casing head or the prior intermediate casing spool. On the other hand, to deal with the expected higher wellbore pressure, the upper flange carries a higher-pressure rating as compared to the lower one.

To end the process, tubing spools are installed. Tubing spools and intermediate spools have somewhat the same features; however, tubing spools are distinct for one reason. The tubing spools can accept a solid body-tubing hook with a lock feature positioned near the top flange. Furthermore, the feature makes sure that the pressure or temperature doesn’t affect the position of the tubing hook. Also, the flange sizes are based on the pressure requirements, and therefore varies accordingly.

Tubing spools are available in a variety such as high manganese steel, stainless steel, and carbon steel. Moreover, the growing exploration and drilling activities for oil across the globe, and oil price recovery are the major factors that fuel the growth of the market. In addition, the increase in the redevelopment of mature oil wells propels the growth of the market as well. According to a report published by Allied Market Research, the tubing spools market is expected to reach $725.8 million, supported by a CAGR of 4.9% by 2026. The advanced technology in the wellhead system offers decreased life cycle cost and greater reliability for pressure seals and suspension points. Moreover, the further developments in the technology for wellhead systems are expected to offer worthwhile opportunities to the market in the coming years.
