Annular Casing Packer – Sealing annular section

Scroll Indication »

Saltel annular casing packers are expandable steel barriers isolating annular sections

Saltel annular casing packer is a stainless steel annulus casing barrier expanded permanently to isolate annulus sections.

Combining plastically deformable steel sleeves with composite elastomer skin guarantees an effective annular seal. It also ensures a robust and permanent annulus barrier.

Cementing applications

Saltel packers enhance cementing operations to guarantee perfect annular integrity.

In such cases, Saltel external casing packer seals annular sections in cement insurance scenarios. (Sometimes in conjunction with cement stage tools)

  • Single-stage cementing (Saltel Xpandable* steel ECP – External casing packer).
  • Multiple stages cementing (Saltel Xpandable* steel ECP – external casing packer).
  • Off-bottom cementing (Saltel Xpandable* steel ECP – external casing packer).
  • Cement backup (Saltel Xpandable* steel ECP – external casing packer).

Other applications

Xpandable Steel Packers can also operate in the following applications.

  • To isolate fracturing stages during openhole ball-drop multistage fracturing operations (Saltel Xpandable* – Frac Packer).
  • For long-term annulus zonal isolation requirements.
    • Reservoir compartmentalization (Saltel Xpandable* steel AZIP – Annular Zonal Isolation Packer).
    • Acid stimulation (Saltel Xpandable* steel AZIP – Annular Zonal Isolation Packer).
    • Plug and abandonment (Saltel Xpandable* steel AZIP – Annular Zonal Isolation Packer).
