Abstract:
A centralizer sub, system, and method for enhanced access to subterranean zones from the surface as used in oil and gas wellbore installations to center a pipe or casing within a wellbore or previous casing string during run-in, installation, or cementing procedures. In under-reamed applications, casing strings and centralizers pass through a smaller casing string before opening up to a larger hole where repeated compressions and decompressions of bow strings of centralizers can compromise integrity and reliability. A centralizer sub, system, and method reduces and controls insertion and running forces to preserve centralizer integrity and down-bore surfaces and equipment.

Claim (Index 8):
The locking mechanism of  claim 7  wherein said receptacle defines holes and wherein ball bearings are inserted into said holes to engage said recesses in said casing sub, and wherein upon engagement of said receptacle with said tab, a nose of said tab maintains said ball bearings in said recesses in said casing sub to prevent movement of said centralizer sub.
