| Abstract | The definition of Geothermal energy is energy contained as heat in the Earth's interior. In order to use this energy, production wells are drilled in specific areas on the earth. Geothermal brine flows artesian and/or they can be getting to the surface by means deep wells. Pumping is often necessary in order to get geothermal fluid to surface. Pumping is some times required to increase pressure or move the fluids from place to place once they are on the surface. In certain geothermal fluids such as those with high carbon dioxide content, maintaining the water under pressure can reduce corrosion and scaling. Because production well pumps are usually of greatest concern and on the surface, pumping is not recurrently a problem well pumps will be considered first. Deep well pumps are used to pump geothermal fluids to the surface and onward to user. As most low temperature geothermal reservoirs are non-artesian, the wells will not produce without pumping. |
