Geothermal Pilot Plant Development: Progress Report and Future Strategy

This summary outlines discussions on the pilot plant project for geothermal exploration. Topics include the concept, purpose, uncertainty of fluid characteristics, risk minimization, fluid sampling, and analysis. The stepwise development plan involves identifying the geothermal fluid, conducting tests and energy planning, and exploring potential energy and chemical processes. The pilot plant group, including experts in well simulation, electrical and chemical processes, and mechanical design, aims to ascertain the viability of the project and assess alternative systems. The current status involves early-phase progress and finalizing the completion strategy. 8 Relevant

  1. Pilot PlantSummary of work Runólfur Maack VGK Engineering

  2. Project meeting, June 24-27, 2001 • First discussions on pilot plant • Pilot plant concept and purpose • Conclusive on a simple pipe solution or concept • …… or the KISS principle

  3. Argumentation • High level of uncertainty of fluid characteristics • To get the feeling for the fluid in as quick or cheap manner as possible • To minimize the risk for damaging the well • Fluid sampling and analysis • The development of the pilot plant will be stepwise

  4. Phase 1 – Identification of the geothermal fluid Litterature study Theoretical analysis Sampling and analysis Recommendations for phase 2 Phase 2 – Utilization of the geothermal fluid Tests Energy process planning Chemical process planning Well completion Stepwise development

  5. Purpose • Obtain first fluid samples • Indication of pressure, temperature, enthalpy • Propose how to deal with the fluid • Processes • Chemicals • Methodology to determine viability of IDDP • Side effects • Reinjection well • Deep well production zone

  6. Processes • Potential energy processes • Thermal • Electrical • Potential chemical processes • Gas • Solids • Liquid
