Expandable - Wireline Deployed Casing Patch

Page last modified
June 30 2024

Wireline deployed straddle utilizing our expandable technology allowing for isolation of wellbore issues whilst providing a maximized post installation ID. The optimised post expansion ID enables continued wellbore access, future intervention, optimizes production rates & maximizes well lifecycle. 

 

Key Features

  • Shoeless design (no drill out of shoe required post install)
  • High expansion capabilities
  • Stackable design with metal to metal sealing, allowing multiple patches to be stacked
  • Recessed seals whilst RIH to optimize RIH OD
  • Available in carbon steel or CRA materials and with gas tight sealing capabilities
  • Deployable on E-line & Coil tubing
  • Expandable technology allows for far larger post installation ID's than conventional methods

Common Applications

  • Isolation of tubular leaks
  • Isolation of unwanted water, gas & sand ingress
  • Corrosion isolation
  • SSSV remediation
  • Isolation of leaking/compromised completions components
Pros & Limitations
1
One-trip system, with no shoe drill out required
1
Larger post installation ID than conventional straddle systems
1
Stackable with metal to metal seals to create longer straddles to suit specific applications
1
Available in standard carbon steel or application specific CRA materials
1
Configurable with smart completion products such as AICDs to provide comprehensive workover solutions
0
When deploying on E-Line, only one straddle joint can be deployed per trip (~40ft). If patching a long section, multiple trips would be required with this system to stack straddles
