Centek /7th January 2014/ RE-RUN
S2 Centralizer Robustness

During a casing run by Det Norske, 30 centralizers on a 20-inch joint string fell over 800 ft after the string became unmoored. Upon retrieval, only one of the 30 S2 centralizers was damaged and the rest were re-run successfully to target depth. This outcome underscores Centek’s single-piece S2 design, which provides industry-leading strength and durability even in extreme handling conditions.

Centek S2 Bow Spring Centralizers remained intact and reusable after a casing string fell more than 800 ft, highlighting their exceptional robustness.

THE CHALLENGE

Det Norske lost 24 joint casing with 30 S2 centralizers in the hole. The string fell over 800 ft. 

THE SOLUTION

30 joint 20 inch casing fished from 800ft vertical hole.

THE RESULT

Only one centralizer was damaged. The majority of the centralizers were re-run and successfully reached TD.

The Centek S2 single piece construction gives it robustness and strength which exceeds that of many competitor products. Although Centek does not recommend the re-use of centralizers when POOH this case study proves that even when subjected to extreme stresses the unique design of Centek centralizers meant that they remained in good condition and could be used repeatedly.
