The function of a wellhead is to provide a physical and mechanical support structure at the surface of an oil or gas well. It acts as an interface between the subsurface reservoir and the surface production facilities. The main functions of a wellhead include:
1. Pressure Management: The wellhead helps in maintaining the pressure control of the well. It provides a barrier to contain the high pressures and fluids within the well and prevents any potential environmental or safety hazards.
2. Control and Monitoring: The wellhead provides access points for various control and monitoring equipment. It allows for the installation of valves, chokes, and other devices to regulate the flow of fluids and gases from the well. It also facilitates the connection of sensors, gauges, and meters to monitor the well's performance.
3. Well Intervention: The wellhead provides a means for well intervention activities such as maintenance, repair, or enhancement of the well's production. This could include tasks like wireline operations, well testing, or installation/removal of downhole tools.
4. Production and Flow Management: The wellhead serves as a connection point for production tubing and casing strings. It allows for the installation of production valves, Christmas trees, and other equipment to control and manage the flow of oil, gas, and other fluids from the well.
5. Well Suspension and Abandonment: In case the well needs to be temporarily suspended or permanently abandoned, the wellhead provides a means to isolate the wellbore and implement proper well-plugging procedures to ensure the integrity of the well and prevent any future leakage.
Overall, the wellhead plays a crucial role in ensuring the safe and efficient operation of oil and gas wells, facilitating production, and providing necessary control and monitoring capabilities.
