Applications

## Engineered for the world's most demanding wells

Exploration & Production

### Production tubing and casing widely used and tested in the most demanding exploration and production wells.

CRA tubular solutions are designed and proven for highly corrosive, HP/HT and deepwater oil & gas wells, where material selection, connection performance and long-term well integrity are critical. SENTINEL® Prime has been specifically designed and tested on CRA materials to withstand these extreme operating conditions.
