The Patuha geothermal field, located in Bandung, Indonesia, plays a pivotal role in the nation's renewable energy portfolio. This article discusses holistic approach of field management, with a primary focus on strategies tailored to maximize geothermal resource utilization, address operational challenges, and ensure the Patuha Geothermal Power Plant operates at optimum Capacity and Reliability. This comprehensive approach covers the entire spectrum of geothermal field management, encompassing both subsurface and surface facilities, and is structured into four key areas: 1. Idle Well Utilization: As the drilling of 12 wells on progress and construction of a power plant still ongoing, the strategic utilization of idle wells takes center stage. This study investigates innovative approaches to tap into the latent potential of these wells during the interim period, ensuring a continuous supply of available steam to the existing power plant unit. The tangible impact of idle well utilization is evident in the remarkable enhancement of the Power Plant's Capacity and Availability Factor, surpassing 95%, a that surpasses industry standards in Indonesia. 2. Scale Removal in Wellbores: Addressing scale deposition within wellbores is critical to maintaining optimal geothermal resource extraction and, consequently, the Power Plant's Capacity Factor. This section meticulously explores a spectrum of cutting-edge technologies and methodologies for efficient scale removal, guaranteeing the unimpeded integrity and longevity of wellbores, while concurrently maximizing plant efficiency. 3. De-bottlenecking Power Plant Facilities: The operational efficiency and reliability of power plant facilities serve as enabler in overall production optimization and contribute significantly to the Availability Factor. Our rigorous approach to enhancing condenser performance, optimizing cooling tower systems, and streamlining water treatment processes has effectively minimized bottlenecks, ensuring a consistent and sustainable power generation process. 4. Preventive and Predictive Maintenance: The enduring operational life of production facilities hinges on the implementation of proactive maintenance practices. We firmly advocate that preventive and predictive maintenance supersedes corrective actions in importance. This maintenance philosophy enables us to proactively identify and address equipment issues, thereby reducing downtime and optimizing the lifecycle of all production facilities, ultimately resulting in a substantially higher Availability Factor for the Patuha Power Plant. The strategies detailed in this article not only contribute to the ongoing success of the Patuha geothermal field but also bear substantial implications for geothermal energy endeavors in Indonesia or even worldwide.
