CASE STUDY The Centek TUR centralizer passes through a restricted ID, returns to zero start and running forces and back to its original design
This operator in the Agbami field needed centralizers that were able to pass through the restricted ID of the 16” casing and then expand to 17 1/2” in the next hole section to ensure proper centralization of the 13 5/8” casing string.
13 5/8” Centek TUR centralizers were passed through a restriction of 14.823” in the 16” casing for 9,250ft and then reverted back to zero start and running forces in the 17 1/2” open hole.
Running the Centek centralizers as the first option helped to save 3 days of rig time, compared to conventional centralizers which may have been unable to get to bottom, first time.
“This is a technology improvement/ innovation that will continue to be deployed for this application in
deep water Agbami wells.”
