• Primary Barrier Elements SN Primary barrier elements used during snubbing operations
• Secondary Barrier Elements – BOPs (Ram Type Preventers) SN Secondary barrier elements (snubbing BOPs) used during snubbing operations
• Secondary Barrier Elements – BOPs (Ram Type Preventers) SN BOP ram configurations for different snubbing operations
• Shearing Devices SN Snubbing shearing devices
• PRESSURE CONTROL (BARRIER ELEMENTS and ENVELOPES) PRINCIPLES SN Grouping barrier elements into barrier envelopes during snubbing operations
• Safely repair or replace failed primary barrier element SN The reasons for changing worn elastomers and temporary suspension of Work
• Safely repair or replace failed primary barrier element SN Secondary barrier elements and envelopes for snubbing if a primary barrier element fails
• Safely repair or replace failed primary barrier element SN Maintaining a double barrier when changing the annular element during intervention
• Operational Considerations (with well control consequences) SN The forces on the workstring created by well pressure
• Operational Considerations (with well control consequences) SN Snubbing pipe in and out of a live well (with square collars/ram to ram)
• Controlled Well Shut in SN How to shut in the well quickly and safely with or without work-string in the hole.
• Snubbing Shear Ram Equipment Operating Limit Explain how running different types of tool string through the shearing device can affect its shearing capability
