Isotope compositions in a network of groundwater wells impaired by an underground blowout
During the drilling of an exploration well in the 1960s, an underground blowout occurred near Sleen, The Netherlands. During approximately 25 months, near-continuous leakage of large amounts of natural gas was released into the subsurface. After the blowout, the local drinking water production company installed a network of groundwater monitoring wells to monitor for possible adverse effects on groundwater quality at the blowout site. Today, more than 50 years after the blowout, the groundwater is still impaired. Data has been correlated with previously published data by Schout et al. (2018) covering description of geology and well depths. During two fieldtrips (November 2019 & October 2020) water samples were collected from several wells covering: - Bulk gas compositions (methane, ethane, propane, oxygen, nitrogen, CO2, Argon). Bulk isotope compositions of methane (δ13C & δH), carbon dioxide (δ13C) and nitrogen (δ15N). - Methane clumped isotope compositions (ΔCD & ΔDD). - Inorganic parameters (hydrocarbons, anions, cations, DOC, alkalinity, nitrate and ammonium). 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.

Analysis of trace metal and major cations was conducted with inductively coupled plasma mass spectrometry (ICP-MS). Large volume (>30L) groundwater samples with dissolved methane gas were collected in pressurised cannisters. In the laboratory, cannisters were depressurised for methane degassing from the water. Headspace methane gas was collected in all metal cannisters for methane clumped isotope analyses. Seperate, small volume (~200ml) gas & water samples were collected in Isoflasks for bulk methane isotope analyses and inorganic parameters. Natural gas composition and bulk methane and CO2 isotope analyses were analysed a Agilent GC. Carbon isotopes of methane on an Agilent 6890N GC interfaced to a Thermo Delta S IRMS. Methane isotopes on an Agilent 7890A GC interfaced to a MAT 253 IRMS. Methane clumped isotope analyses are conducted on a Thermo Scientific IRMS-253 Ultra.
