High deviation, heavy-duty fishing, North Sea

 

Technical Challenge:

High deviation, heavy-duty fishing in the North Sea.

Peak Solution:

High-deviation toolstring consisting multi-function rope socket, Peak Power Jar, Linear Jar, WellGlide roller-centralizer sub.

Customer:

Wireline service company, North Sea.

Well type:

5 ½-in oil producer (77 degree deviation).

The Challenge:

A wireline service company in the North Sea recently used Peaks innovative tools to provide a solution for recovering a competitor’s bridge plug that had become stuck downhole. The 5 ½-in bridge plug was set at 10,500 ft in a highly deviated 77 degree well, giving additional concerns about the challenge of deploying intervention tools to such depth and deviation.

Considerations:

Unlike other roller systems available on the market, Peak's WellGlide sub has unique features that make it perfectly suited to deploying toolstring in highly-deviated wells. The roller subs can be positioned along the length of the toolstring to lift it clear of any foreign bodies, sand, scale or debris in the tubing. Moreover, they prevent “bellying out” and eliminate any friction between the toolstring body and the tubing wall.

Summary:

Peak provided a complete toolstring, comprising of a 2 11/16-in fishing string run on 5/16-in braided line cable. Due to their rugged design, Peak’s WellGlide subs can be supplied with UHD Peak QC connections. These were incorporated into the toolstring as well as Peak Power Jars and two Linear Jars, to provide the ultimate toolstring performance at high deviation.

Peak’s high-deviation toolstring solution is a powerful combination of tools that reached depth for the customer without any problems.
