A wellhead is the surface equipment placed at the top of a geothermal well that controls and monitors the flow of hot water or steam from underground. Think of it like a sophisticated tap system that manages how geothermal resources come out of the ground. It's a crucial piece of equipment that helps energy companies safely extract heat from the Earth to generate electricity. When someone mentions wellhead experience in their resume, they're typically talking about working with this equipment to control pressure, temperature, and flow rates at geothermal power plants.
