Management of an EGS reservoir. Successful management of an EGS reservoir requires careful monitoring of variables. Heat loss during the extraction of the fluid from the reservoir must be minimised, the natural radioactivity must be controlled and the efficiency of the electricity generating plant must be monitored. The key to financial viability in EGS technology lies in being able to produce energy over long periods with no need to make expensive repairs (such as the unplanned drilling of additional xxxxx). When the reservoir is operated, various operating techniques can be chosen, and it must be determined what the optimal technique for an EGS plant is. Thus, the reservoir can be exploited, e.g., by Doublet or Multi-well systems. While the first technique is simpler and cheaper, the second provides more flexible results that let you create a network of several reinjection and production xxxxx, reducing the pressure and minimizing the seismic hazards that may arise from exploitation (an aspect of great importance). Additionally, a correct placement of reinjection and production xxxxx, which has a direct impact on the performance of the facility and whose influence, therefore, must be a study factor. Similarly, it may be chosen for conversion into electricity, other techniques among which worth mentioning the Organic Rankine Cycle (ORC) and the Double-Flash Power Plant. Thus, a clear understanding of, and a repeatable strategy for, addressing long-term EGS operational barriers is necessary. Technology solutions to address short-circuiting, like other concerns with long-term operation, will require a much larger and broader experience base. Where natural fractures exist, stimulation can be performed using low-pressure injection [17]. Through investigation of natural fractures and its suitability to the operation should be conducted before hydraulic fracturing. Techniques such as side-leg concept where the pressure is distributed over two separated ends of injection well can be used [18] If there is risk from High-pressure injection; reduce injection pressure at the cost of operational efficiency [8]. Maintain acceptable flow rates and reduce or eliminate fluid loss [7]. Choose injection fluid, which do not interact with the formation. Use PPE and radioactive counters [18] Validate design prediction with operating data [19]. Mitigate reservoir and surface problems that could lead to short circuiting [7].
