Vertical Shock Absorber Drill Stem Test Tools - 105 MPa / 15,000 PSI High Pressure Rating for Oil Well Operations
The Vertical Shock Absorber is engineered to protect pressure-measuring equipment and sensitive components in the workstring during drill stem testing operations. It effectively mitigates shock loads transmitted through the workstring when tubing-conveyed perforating (TCP) guns are fired.
| Size (in) | OD (mm) | ID (mm) | Working Pressure (MPa) | Service Environment | Working Temperature | Connection |
|---|---|---|---|---|---|---|
| 3 7/8 | 98.5 | 45 | 105 | Mud, oil and natural gas with H2S and acid | Max 450°F | EUE IF |
| 5 | 127 | 57 | 105 | Mud, oil and natural gas with H2S and acid | Max 450°F | EUE IF |
- Constructed from high-strength Alloy Steel or Inconel materials
- Easy installation and maintenance procedures
- Compatible with slim hole and cased hole drill stem testing applications
- High pressure rating of 105 MPa (15,000 PSI)
The Vertical Shock Absorber is typically installed between the gauge carrier and tubing-conveyed perforating guns, positioned below the casing packer. For optimal shock absorption performance, it is recommended to run in conjunction with a drag block assembly.
