split casing repair with casing patch

casing repair techniques

Scroll Indication »

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.
