| Abstract | A geothermal system could include multiple geothermal fields, and it is common to find later that such separate fields are associated. Therefore, when developing a reservoir model, it is a prudent strategy to include the entire geothermal system to leave the potential for further modifications in the future. However, acquiring the necessary data for all the fields or constructing the whole model from the beginning can be difficult. In this research, the Domes field, a part of the Olkaria geothermal system in Kenya, is extracted from the entire model and used for detailed construction. This paper will introduce how the unsymmetrical block sizes on the borders of the model influence the fluid flow in the reservoir. It also discusses techniques for making modifications along with calibration strategies considering fluid inflow from neighboring fields. |
