Pressure increase as a function of supercritical CO2 (scCO2) mass fraction in the mixture was monitored.\nThe plot shows the apparent compressibility of Stimufrac as a function of scCO2 mass fraction obtained in a pressure range between 2100-7000 psi at 250degC.\n\nAt small mass fractions of scCO2 the compressibility increases probably due to the dissolution/reaction of CO2 in aqueous PAA and reaches a maximum at mCO2/mH2O = 0.06. Then, compressibility decreases showing a linear relationship with scCO2 mass fraction due to the continuous increase in density of the binary fluid associated to the pressure increase.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://gdr.openei.org/files/870/StimuFrac%20compressibility.xlsx", "description": "This excel sheet reports compressibility of PNNL's StimuFrac fluid as a function of CO2 concentration", "format": "xlsx", "mediaType": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "title": "StimuFrac Compressibility.xlsx"}], "identifier": "https://data.openei.org/submissions/7060", "issued": "2016-04-29T06:00:00Z", "keyword": ["CO2", "StimuFrac", "carbon dioxide", "compressibility", "fluid compressibility", "geothermal", "hydraulic fracturing", "mass fraction", "stimulation"], "landingPage": "https://gdr.openei.org/submissions/870", "license": "https://creativecommons.org/licenses/by/4.0/", "modified": "2019-10-18T15:39:19Z", "programCode": ["019:006"], "projectLead": "Sean Porse", "projectNumber": "FY16 AOP 1324", "projectTitle": "Reservoir Stimulation with Operational Monitory for Creation of Enhanced Geothermal Systems", "publisher": {"@type": "org:Organization", "name": "Pacific Northwest National Laboratory"}, "spatial": "{\"type\":\"Polygon\",\"coordinates\":[[[-116.7502,35.2279],[-112.8941,35.2279],[-112.8941,39.3634],[-116.7502,39.3634],[-116.7502,35.2279]]]}", "title": "StimuFrac Compressibility as a Function of CO2 Molar Fraction"}
