What are the advantages and disadvantages of using a 'packer' for well completion in a highly fractured geothermal reservoir?

A packer is a downhole tool used to isolate sections of a wellbore. In a highly fractured geothermal reservoir, using a packer for well completion offers both advantages and disadvantages. One advantage is zonal isolation. Packers can isolate specific fracture zones, allowing for selective production or injection. This can improve well performance by focusing on the most productive fractures and preventing water breakthrough from less productive zones. Another advantage is controlling fluid flow. By isolating different fracture zones, packers can help to control the flow of geothermal fluids, preventing commingling of fluids with different temperatures or chemical compositions.....
