• Loss of Pressure Control During Well Intervention Operations SN What to do if there is a leak from the surface equipment to the atmosphere during a snubbing operation
• Loss of Pressure Control During Well Intervention Operations SN What to do if pressure is seen at surface inside the work string during a snubbing operation
• Loss of Pressure Control During Well Intervention Operations SN What to do if an alarm sounds when the workstring is in the well and you are required to muster in a safe area
• Loss of Pressure Control During Well Intervention Operations SN What to do if the workstring down hole check valves (back pressure valves) leak while in the hole during a snubbing operation
