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:
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.
