Casing damage is traditionally seen in older wells due to corrosion caused by chemical reactions and erosion. As a result of particle abrasion and wear fatigue caused by repeated stress, solid particles are suspended in liquids or gases abrade. However, with the emergence of extended horizontal and winding bores, casing damage is increasingly being seen in newer wells due to the wear sustained during installation. This wear can lead to corrosion, erosion, and fatigue in the casing, resulting in damage. There are many reasons behind casing damage, and casing repair techniques depend on the situation and condition of the well.
Casing repair techniques for a well depend on various factors, such as the size and condition of the casing. Also, the magnitude of any leaks or damage and the economics of the well. Saltel offers a range of isolation, repair, and replacement solutions, designed to help ensure maximum performance and efficiency. These solutions include a variety of technologies and techniques, such as cementing, plugging, permanent abandonment, and casing pressure testing.
Saltel Casing Patch is an innovative technology for restoring and protecting damaged casing. It offers a permanent solution that prevents annular fluid/gas flow and enhances production. The Patch enables large ID access, making it possible to use standard tools with standard rih od. In addition, the Patch is easy to install for both onshore and offshore applications. With the Patch, operators can enjoy increased safety and reliability. With effective cost and time savings that come with increased production.
Saltel Xpandable Steel Patch is a repair and stabilization solution for casings, allowing for increased production and blocking any fluid or gas that may travel in the annulus. It is pressure resistant, making it an ideal solution for corrosion prevention and avoiding costly abandonment. The patch provides a large inner diameter entrance for downhole equipment, and is easy to install, making it a reliable and efficient solution for many operations.
Depending on the conveyance and time span for the intervention, the patch installation can be classified under light or middle workover services.
