The current work’s main aims are to discuss and introduce the main aspects of geothermal wells and reservoirs, including well systems, heating, drilling, and completion. There are several systems and methods for extracting heat energy from underground formations, such as open/closed-looped, vertical/horizontal, pond, and slinky mechanisms, which require different distribution and efficient energy transfer systems. The geothermal well completion method and cementing process are similar to hydrocarbon wells. However, the materials and cement used in geothermal wells must be compatible with hot water and high-pressure-high-temperature (HPHT) steam. Therefore, careful planning for compatible drilling-completion operations with geothermal reservoirs is essential. |
