Retrieval of injection valve from tubing crossover at 10,400 ft

 

Technical Objective:

Retrieval of injection valve from tubing crossover at 10,400 ft

Customer:

Independent oil producer, North Sea

Well type:

Oil producer (max 40 degree deviation)

Products/Services:

Peak's high temperature/high strength (HTHS) magnet

The Challenge:

A customer was retrieving a bridge plug and injection valve to surface when the injection valve separated from the plug and landed at the 5 1/2-in by 4 1/2-in tubing crossover at 10,400 ft.

An efficient method to fish the injection valve without causing damage to the tubing crossover was required so the injection value could be pulled and a new injection valve set.

Considerations:

The following key requirements and concerns were identified:

  • A timely and effective intervention was critical to allow a new injection valve to be installed thereby minimising the impact on production
  • Damage to the tubing crossover was to be avoided

Peak’s Solution:

Peak’s 4.5-in OD HTHS Magnet was run downhole on slickline to the location of the tubing crossover at 10,400 ft.

At depth, the pick-up weight increased significantly - by over 50 lbs - confirming the HTHS magnet had a magnetized hold of the injection valve on the first attempt.

Due to the powerful strength of the HTHS magnet, the injection valve was successfully pulled to surface.

Value to Customer:

All operations were carried out safely and efficiently, minimizing the period of reduced production from the well.

  • The tools were run in-hole without issue and successfully fished the injection valve within hours and on the first attempt
  • The customer did not need to rent additional tooling to carry out the operation
  • Downward jarring was avoided thus preventing damage to the tubing crossover
  • A new retrievable bridge plug and injection valve are now set in the well and full injection available
