The project placed emphasis on establishing an inverse modelling methodology to use on three different aspects of geothermal power development, i.e. analysing a geothermal system’s workload, a thermal and structural analysis of wells and wellheads, and optimizing the steam-gathering systems and examining the functionality of separator stations. In the project, experiments have been performed on pressure drops, temperature changes and quality factors used with inverse analysis to adjust models that have been developed for analysing those factors. The main objectives: to develop
a technology to improve usage of geothermal reservoirs and to optimize the placement of wells, the steam-gathering system and separators. Secondly, to enlarge know-how in this important field of geothermal exploration in Iceland.
A key element in the project has been to do all experiments and development work directly on site, using real geothermal gas produced under industrial conditions from fully operating power plants. This will naturally bring in numerous problems and unexpected incidents that would not happen if similar experiments were to be done under artificial laboratory conditions using controlled, synthetic gas.
