7" 29# L80 JFE BEAR Seamless Casing (R3) – API 5CT Premium Connection

The 7" 29# L80 JFE BEAR Seamless Casing (R3) is a premium tubular product engineered to meet the demands of modern oil and gas drilling operations. Constructed from API 5CT L80 grade steel, it offers excellent resistance to stress, collapse, and moderate sour gas environments.

Outfitted with the JFE BEAR premium connection, this casing delivers superior gas-tight sealing through a metal-to-metal seal, ensuring zero leakage under high-pressure and high-temperature (HPHT) conditions. The JFE BEAR thread design enhances joint strength, minimizes galling during make-up, and is ideal for wells requiring advanced sealing performance.

The Range 3 (R3) configuration provides extended pipe lengths of approximately 40–42 feet, reducing the number of connections per string and increasing installation efficiency in deep wells.

This casing is ideal for intermediate or production casing strings in challenging wellbore environments, including horizontal drilling and shale plays.
