Cement Backup

Once expanded against the borehole, Xpandable Steel Packers compartmentalize the annulus into independent parts.

The current article explores the potential for expandable steel packer technology to be used in primary cement backup when drilling new wells. Cement is a critical component in the well construction process, providing a seal between the reservoir, geological formations, and the surface of the well. This seal ensures that the well remains safe and secure throughout its lifetime.

Expandable steel packer technology offers a unique approach to cement backup, as the packers can come with a robust stainless-steel design. The expandable metal packers can withstand difficult running-in operations, allowing for a more secure and reliable seal. Additionally, this technology can also serve to reduce the risk of cement failure due to improper placement or movement of the packers. Using expandable steel packers in primary cement backup alleviates the risk of well failure. It provides, at the same time, a secure and reliable seal.

Therefore, any issue encountered during the cement placement can lead to major safety and environmental issues. The issues can range from structural and cosmetic damage to the release of hazardous chemicals or contaminants into the aquifers and the environment, which can be dangerous to people and wildlife. Furthermore, if the issue you do not address it quickly, it can worsen and cause more serious and costly damage.

Saltel Xpandable Steel Packers expands in the uncured cement. Expansion against the borehole divides the annulus into separate parts, blocking flow between them during curing. The packers offer long-term annulus security and cement backup through the life of the well. These reliable and permanent packers are ideal for completing poor cement sheaths.
