Kinetics of enhanced cementation reactions for CO2 leakage remediation and fault healing processes

This dataset presents the amount of different magnesium carbonates under different conditions. Here, using batch reactor experiments and mineralogical characterization, we explored magnesite precipitation kinetics in chemically complex fluids whereby the impact of fluid acidity and alkalinity, NaCl, and MgO nanoparticles was investigated. The dataset was created within SECURe project (Subsurface Evaluation of CCS and Unconventional Risks) - https://www.securegeoenergy.eu/. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 764531

Title: INSPIRE Implementing rules laying down technical arrangements for the interoperability and harmonisation of Geology

Title: Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services

Statement: The control experiments were conducted with 15 mL of simulated fluids containing 0.3 M MgCl2 and 0.3 M Na2CO3, in Teflon-lined steel batch reactors. The acidity, alkalinity, background electrolytes, and hydrophilic particles influenced experiments were conducted using HCl (10-5 M), NaOH (10-5 M), NaCl (0.5, 1.0, 1.5, 2.0 M), and MgO nanoparticles (40-60 nm) (6, 12, 18, 24 mg) to test different fluid compositions for magnesite formation, respectively. A temperature of 200 °C was applied for the experiments to generate anhydrous magnesite at favorable time scales for laboratory experiment. The reaction products were analysed by X-ray diffraction (XRD) to identify the mineralogical composition. The pH of the supernatant solution after centrifugation (5 min at 4500 rpm) was tested using a pH meter.
