GU-750 – HSE Precautions for NORM Well Re-Entry – PDO

To provide safe systems of work when handling equipment and fluids potentially contaminated with NORM during well re-entry operations with work-over or drilling rigs.

This procedure shall apply to all well re-entry operations carried out by drilling or work-over rigs. All wells, which have been previously active (not new wells), shall be considered NORM contaminated unless demonstrated otherwise by measurements using the correct meters. A separate procedure exists for the wireline and coil tubing unit operations of production wells.
