Frontier Observatory for Research in Geothermal Energy: Phase 1 Topical Report Fallon, NV

Abstract

Further dissemination authorized to the Department of Energy and DOE contractors only; other requests shall be approved by the originating facility or higher DOE programmatic authority. During Phase 2A, 2B, and 2C, the Fallon FORGE site will be instrumented and readied to test new technologies and techniques in Phase 3. In Phase 2A, an Environmental Information Volume will be completed while a schedule to complete the NEPA process and obtain required permits will be completed. Additionally, preliminary telemetered seismic monitoring of the site will be deployed to complement existing seismic monitoring activities at the Fallon FORGE site. During Phase 2B all reviews, permits, and approvals initiated in Phase 2A will be obtained in accordance with NEPA and other local and state regulations. It is anticipated that these permits will be obtained early in Phase 2B and additional site characterization allowed by NEPA and applicable permits to begin. Phase 2B will also include the completion of the Induced Seismicity Mitigation Plan that will incorporate recorded site MEQ data and associated analyses into a Probabilistic Seismic Hazard Analysis, Criteria for Damage and Vibration, and Mitigation Actions for field testing. In 2C the site is brought to readiness for FORGE implementation through, at a minimum, additional surface and subsurface site characterization, deployment of high resolution seismic monitoring, geologic model refinement, and reservoir modeling. Additionally, a Science and Technology Analysis Team (STAT) will be assembled to provide technical guidance to the FORGE team and to ensure DOE objectives are incorporated in FORGE execution. As a result of working with the STAT to assess current technology, establish technical baseline information and performance metrics for FORGE work, and review the FORGE implementation plan, topics for the first round of competitive solicitations will be developed and a draft solicitation produced. Where applicable and appropriate, DOE may elect to have the Fallon FORGE team incorporate testing of methods and tools developed by separately funded DOE researchers into FORGE activities.

Sistemas geotérmicos mejorados: revisión y análisis de casos de estudio

“…Se anticipa que se perforarán múltiples pozos profundos en el sitio, a profundidades que van desde 1500 hasta 2000 m. Se perforarán pozos poco profundos para monitorear actividades subsuperficiales. En apoyo del trabajo para la fase 3, el equipo está trabajando actualmente con la Oficina de Campo de Stillwater de la Oficina de Administración de Tierra y Naval Air Station Fallon para preparar la documentación ambiental necesaria y recopilar datos para lograr caracterizar el sitio más detalladamente y reducir la incertidumbre geológica (Blankenship et al, 2017 GT-1 (785 m) Primer pozo usado para medir el flujo calor en el sitio, adquirir muestras del basamento rocoso, y para probar la fracturación hidráulica EE-1 (2930 m) Pozo de inyección (Fase 1) GT-2B Pozo de producción (Fase 1) EE-2 (3500 m) Pozo de producción (Fase 2) EE-3 (3500 m) Pozo de inyección (Fase 2) PC-1 (663,9 m) Pozo de monitoreo de sismicidad PC-2 (663,9 m) Pozo de monitorio de sismicidad EE-3A (2900 m) Redirección de pozo EE-3…”
