Retrievable Packers
Mechanical-set, wireline-set and tension packer options for completion and abandonment work.
Six packers across two families
Also available: lock-set packers, hydraulic-set packers and anchors, tandem tool test packers and mechanical double grip packers.
Double Grip Retrievable Packers
Set in tension or compression, with an optional safety release.
Tension Packers
For shallower completions and injection service where the string is held in tension.
Available Models
| Model | Set method | Pressure rating | Casing sizes |
|---|---|---|---|
| AS1-X 7K | Mechanical set | 51.7 MPa (7,500 psi) | 73.0 – 168.3 mm (2⅞″ – 6⅝″) |
| AS1-X 7KW | Wireline set | 51.7 MPa (7,500 psi) | 73.0 – 168.3 mm (2⅞″ – 6⅝″) |
| AS1-X 10K | Mechanical set | 68.9 MPa (10,000 psi) | 114.3 – 244.5 mm (4½″ – 9⅝″) |
| AS1-X 10KW | Wireline set | 68.9 MPa (10,000 psi) | 114.3 – 244.5 mm (4½″ – 9⅝″) |
AS1-X 10K packers for 193.7 – 244.5 mm (7⅝″ – 9⅝″) casing are rated 51.7 MPa (7,500 psi). The AS1-X 7K and 7KW come in a sour service version to NACE MR0175 for H2S, and both families come in a range of material and elastomer options. Bore and gauge ring sizes per casing weight are in the Tools Catalogue.
Built for completion and abandonment work
The AS1-X sits at the centre of Dan’s completion inventory. It is the tool most of our completion and abandonment programs are built around — setting and testing, isolating zones for stimulation, and holding pressure during suspension work.
Available Models
| Model | Set method | Pressure rating | Casing sizes |
|---|---|---|---|
| Model Ti Tension Packer | Mechanical tension set | Application dependent | 60.3 – 244.5 mm (2⅜″ – 9⅝″) |
| TSP Coil Tension-Set Packer 10K | Coil tension set | 68.9 MPa (10,000 psi) | 114.3 – 177.8 mm (4½″ – 7″) |
The string weight, depth and the pressure you need to hold decide which of the two suits the well. Both have an adjustable shear release: if the packer will not unset the normal way, a pull shears it free so it can be retrieved. The Model Ti comes with elastomer and metal options for hostile wells.
Shallower wells, lower differential
Tension packers are not a substitute for a double grip packer on a high-pressure completion, and we will say so if that is what the well needs. Where they win is on shallower wells and coil interventions, where setting by tension is simpler, faster and does not require the string weight a compression-set tool depends on.
Retrievable packers in the Tools Catalogue
Bore sizes, gauge ring outside diameters, casing weight ranges and connection options for every packer in this family are tabulated in the Tools Catalogue, pages 4 to 12.
