903 Well Site Completion and Servicing Safety

Removing the Wellhead

The wellhead is the equipment at the surface of the well that connects to the casing and controls the flow of oil, gas, or other fluids. Before workover or servicing can begin, the wellhead must be removed from the casing flange. This step is important because it gives workers access to the wellbore and allows other equipment, such as a workover rig, to be connected.

Removing the wellhead must be done carefully and only after the well has been properly shut in. If the well is still under pressure, it can be extremely dangerous. Workers must make sure all pressure is released and the area is secure before starting this task.

During removal, tools like hydraulic wrenches and hammers may be used to loosen bolts, valves, and other fittings. Because the wellhead is heavy and under high stress, the risk of injury is high if proper procedures are not followed.

Potential Hazards

Several hazards may occur while removing the wellhead. These hazards can cause serious injuries if not controlled. Workers must stay alert and follow safety guidelines at all times.

Possible Solutions

To work safely when removing a wellhead, workers must follow the correct steps and use proper protective equipment. These solutions can help prevent accidents and injuries:

• Stand clear of valves and fittings when removing fitting or bleeding off pressure.
• Check wellhead pressure and bleed pressure off before removal.
• Use the correct tools for each task.
• Inspect the tools before each use.
• Wear proper PPE including safety glasses.
• Keep fingers and hands away from pinch points.
• Cover open cellars.
• Wear fall protection as appropriate.
• Implement a confined space entry program.
