First, the stimulation pumps used were designed to run for weeks and deliver large volumes of water at moderate well-head pressure. Second, to stimulate multiple zones, AltaRock developed thermo-degradable zonal isolation materials (TZIMs) to seal off fractures in a geothermal well to stimulate secondary and tertiary fracture zones. The TZIMs degrade within weeks, resulting in an optimized injection/ production profile of the entire well. Third, the project followed a project-specific Induced Seismicity Mitigation Plan (ISMP) to evaluate, monitor for, and mitigate felt induced seismicity. Stimulation started October 17, 2012 and continued for 7 weeks, with over 41,000 m3 of water injected. Two TZIM treatments successfully shifted the depth of stimulation. Injectivity, DTS, and seismic analysis indicate that fracture permeability in well NWG 55-29 was enhanced by two orders of magnitude.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://gdr.openei.org/files/774/Phase%202.1%20Report_4.24.14.pdf", "description": "Report detailing the findings of the Newberry EGS Demonstration Phase 2.1 which aimed to stimulate the existing fracture network.", "format": "pdf", "mediaType": "application/pdf", "title": "Phase 2.1 Report.pdf"}], "identifier": "https://data.openei.org/submissions/6967", "issued": "2014-03-10T06:00:00Z", "keyword": ["EGS", "NEWGEN", "demonstration", "diverter material", "geothermal", "groundwater monitoring", "hydraulic", "microseismic monitoring", "stimulation", "temperature monitoring"], "landingPage": "https://gdr.openei.org/submissions/774", "license": "https://creativecommons.org/licenses/by/4.0/", "modified": "2024-07-09T16:56:47Z", "programCode": ["019:006"], "projectLead": "Lauren Boyd", "projectNumber": "EE0002777", "projectTitle": "Newberry EGS Demonstration", "publisher": {"@type": "org:Organization", "name": "AltaRock Energy Inc"}, "spatial": "{\"type\":\"Polygon\",\"coordinates\":[[[-121.4333333,43.51666667],[-121.0333333,43.51666667],[-121.0333333,43.91666667],[-121.4333333,43.91666667],[-121.4333333,43.51666667]]]}", "title": "Newberry EGS Demonstration: Stimulating the Existing Fracture Network Report"}
