The primary limitation that makes commercial EGS infeasible is our current inability to cost-effectively create high-permeability reservoirs from impermeable, igneous rock within the 3,000-10,000 ft depth range. Our goal is to develop a novel fracturing fluid technology that maximizes reservoir permeability while reducing stimulation cost and environmental impact. Laboratory equipment development to advance laboratory characterization/monitoring is also a priority of this project to study and optimize the physicochemical properties of these fracturing fluids in a range of reservoir conditions. Barrier G is the primarily intended GTO barrier to be addressed as well as support addressing barriers D, E and I.\n", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://gdr.openei.org/files/455/Acoustic%20emission%20description%20on%20two%20fracturing%20experiments%20on%20Newberry%20samples%201%20and%204%20%281%29.docx", "description": "Description of the videos generated during acoustic emission analysis on lab-scale fracturing experiments performed on samples Newberry-1 and Newberry-4 obtained at 706 m depth.", "format": "docx", "mediaType": "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "title": "Acoustic Emission Analysis.docx"}, {"@type": "dcat:Distribution", "accessURL": "https://gdr.openei.org/files/455/Gel%20expansion-based%20Stress%20analysis%20%281%29.docx", "description": "Analysis of the pressure generated by PNNL fracturing fluid as a result of the CO2-triggered volume expansion of a polymer solution", "format": "docx", "mediaType": "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "title": "Gel Expansion-Based Stress Analysis.docx"}, {"@type": "dcat:Distribution", "accessURL": "https://gdr.openei.org/files/455/Newberry-1.mp4", "description": "Video showing the response of 8 sensors located around the rock sample being fractured by PNNL fracturing fluids at two different confining P/T", "format": "mp4", "mediaType": "application/octet-stream", "title": "Acoustic Signature for Newberry-1.mp4"}, {"@type": "dcat:Distribution", "accessURL": "https://gdr.openei.org/files/455/Newberry-4.mp4", "description": "Video showing the response of 8 sensors located around the rock sample being fractured by PNNL fracturing fluids at two different confining P/T", "format": "mp4", "mediaType": "application/octet-stream", "title": "Acoustic Signature for Newberry-4.mp4"}, {"@type": "dcat:Distribution", "accessURL": "https://gdr.openei.org/files/455/XMT%20images%20%26%20permeabilities%20before%20and%20after%20fracturing%20Newbery%20and%20Coso%20EGS%20cores%20at%20different%20P-T-pHs%20%281%29.docx", "description": "A summary of permeability values and x-ray microtomography (XMT) images before and after lab-scale fracturing exps at different confining pressures, temperatures and pH on rock cores from two different EGS reservoirs, Newberry and Coso.", "format": "docx", "mediaType": "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "title": "XMT Images and Permeabilities.docx"}], "identifier": "https://data.openei.org/submissions/6766", "issued": "2014-09-15T06:00:00Z", "keyword": ["EGS", "XMT", "acoustic emission", "acoustic signature", "fracture response", "fracturing", "geothermal", "igneous rock", "laboratory scale", "permeability", "rheoreversible fluids", "stress", "volume expansion", "x-ray microtomography"], "landingPage": "https://gdr.openei.org/submissions/455", "license": "https://creativecommons.org/licenses/by/4.0/", "modified": "2017-06-27T16:56:53Z", "programCode": ["019:006"], "projectLead": "Dan King", "projectNumber": "FY14 AOP 1.3.2.2", "publisher": {"@type": "org:Organization", "name": "Pacific Northwest National Laboratory"}, "spatial": "{\"type\":\"Polygon\",\"coordinates\":[[[-121.4333333,36.049347445098],[-117.72810665039,36.049347445098],[-117.72810665039,43.91666667],[-121.4333333,43.91666667],[-121.4333333,36.049347445098]]]}", "title": "Reservoir Stimulation Optimization with Operational Monitoring for Creation of EGS"}
