Antelope Oil Tool & Manufacturing Co. LLC added single-piece centralizers CentraMax RT1 and CentraMax PT1 to its Centramax series for cementing operations, the company said April 7.

These are designed for high performance in reciprocating and rotation well applications, as an alternative to centralizer subs in close tolerance applications.

The single-piece design has mechanical integrity, high yield and tensile strength and eliminates potential weld failures. The slip-on design handles any casing weight, grade and threaded connection types.

CentraMax RT1 and CentraMax PT1 provide low starting and running forces inside tight tolerance sections. They also provide strong restoring forces to centralize casing string in underreamed hole sections.

Houston-based Antelope Oil Tool & Manufacturing Co. LLC provides centralization and cementation equipment for the domestic and international oil and gas industry.
