What do I need to know about API 10D testing for centralizers and stop collars?
API 10D testing helps operators assess whether bow-spring centralizers can deliver the standoff and running performance required to support effective casing placement, cementing, zonal isolation, and long-term well integrity.
With the introduction of API 10D 7th Edition and the removal of the API monogram program, operators can no longer rely on API accreditation alone to confirm compliance. This means drilling, procurement, and QA/QC teams need to take a more active role in checking supplier datasheets, test methods, traceability, reporting standards, and whether products have been tested to the latest edition.
Centek’s Operator’s Guide to API Testing for Centralizers and Stop Collars explains the key testing protocols, reporting requirements, re-testing rules, stop collar guidance, and the role of accurate test data in simulation and downhole performance.
