Abstract
A multidisciplinary framework for the sustainable utilization and efficient use of Patuha geothermal field is proposed here to evaluate the development of 110 MW. The significance of applying a strategic approach is emphasized, taking into account the connections between the analysis of geothermal systems, resources, and power production. A three-dimensional numerical model of the Patuha reservoir for fluid flow and heat transfer was developed using the TOUGH2 simulator based on the analysis of updated integrated geoscience data combined with well data. The model was validated for natural state and production history, then used for reassessment of the geothermal resources using probabilistic resource assessment and experimental design and for reservoir plant optimization. Several case studies were conducted, which concluded that the model could be used as a practical tool to support the Patuha development plan. The forecast indicates the reservoir sustains the additional capacity of 55 MW for Patuha Unit 2, which is at the threshold of 116 MW from a probabilistic resource assessment. According to the base case scenario, it was determined that 18 additional make-up wells are required to maintain 30 years of production.
期刊介绍:
Geothermics is an international journal devoted to the research and development of geothermal energy. The International Board of Editors of Geothermics, which comprises specialists in the various aspects of geothermal resources, exploration and development, guarantees the balanced, comprehensive view of scientific and technological developments in this promising energy field.
It promulgates the state of the art and science of geothermal energy, its exploration and exploitation through a regular exchange of information from all parts of the world. The journal publishes articles dealing with the theory, exploration techniques and all aspects of the utilization of geothermal resources. Geothermics serves as the scientific house, or exchange medium, through which the growing community of geothermal specialists can provide and receive information.
