Recovery of magnetic junk in high temperature wells

 

Technical Challenge:

Recovery of magnetic junk in high temperature wells

Peak Solution:

High temperature/high strength magnet

Customer:

OMV, New Zealand

Well Type:

1200 ft true depth, 82 degree deviation well, Maari field, New Zealand

The Challenge:

The customer was completing a workover on a well when three control line/ESP cable clamps broke free whilst retrieving the completion back to surface.

Considerations:

  • The clamps were lost in 10 ¾-in casing with 82 degree deviation
  • The well fluid contained approximately 3 percent KCl, however the Peak magnet is highly resistant to CO2 and H2S environments.

Summary:

Using a Peak 2.72-in OD high temperature/high strength magnet, the service company working on the well at the time managed to recover the clamp pieces in five tractor runs on e-line and, due to the powerful strength of the Peak magnet, even retrieved two blocks and allen key bolts lost from an earlier clamp.

Value to Customer:

Compared to other magnets available on the market, Peak’s high temperature/high strength magnet is particularly strong and can withstand prolonged exposure to very high downhole temperatures (500 degF) without losing magnetic strength. Peak’s magnet is available in a range of sizes (1.75 in up to 4.5-in OD) to suit the application and well geometry.
