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 12):
The casing sub of  claim 10  wherein the expandable band comprises:\n at least one compression spring fitted around said casing sub; and \n at least one wrap band spring fitted around said casing sub.
