Primary cement backup challenges

Annulus cementing is essential as a primary well barrier to secure the environment, and ensure the efficiency of high pressure stimulation operations below.

Efficient primary cementing can be difficult, particularly when there is potential crossflow, a tight borehole, or a risk of gas migration.

Xpandable Steel Packer Solution

Using a high pressure steel barrier to seal the annulus while the cement is setting will prevent crossflow or channeling, support the cement to keep it in place, eliminate any gas migration, and help to centralize the casing. A steel packer run on the casing can be expanded into the wet cement to eliminate these potential problems and ensure cement and annulus integrity..
