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 9):
The locking mechanism of  claim 7  wherein said receptacle includes pivoting appendages capable of engaging said recesses in said casing sub, said pivoting appendages being held apart by engagement with said tab to prevent movement of said centralizer sub.
