Optimization of Geothermal Wells and Production Systems

Abstract

Maintaining geothermal well energy efficiency, as well as the efficiency of a production system, requires a detail analytical approach. One of the main conditions is to synchronize the performance of the surface system with the production well?s operational conditions. Therefore it is essential to determine the most optimal duration of the wells flowing and the time of installation of the pump to achieve the required geothermal fluid quantities and operating pressure. The surface system should be designed and constructed to provide the geothermal fluid of given parameters at any moment. The key condition is to eliminate both free and dissolved gases from the fluid, which are mainly of methane type in the Pannonian basin. As the production systems in the Province of Vojvodina are automatized, it is very important to know the well's performance type ? whether it is flowing or working with submersible pump. It is also very important to accurately determine the pump's installation depth, owing to the presence of free and dissolved gases, to achieve continuous operation and prevention of cavities.
