Soil Gas and Flux Survey Data for a CO2 Leak in Qinghai, China, 2014

Eight days of soil gas and soil flux surveys characterize a surface CO2 leak from a failed well at a research site in Qinghai, China. The dataset includes measurements from regular and irregular sampling grids, soil gas well analysis, and carbon-13 isotope data. It was published in the International Journal of Greenhouse Gas Control in 2016 and is hosted by Geoscience Australia Data.

Use Cases

• Mapping CO2 leak distribution and magnitude based on soil flux survey grids.
• Estimating total field CO2 emission rates based on cubic interpolation of flux data.
• Identifying the source of leaking CO2 based on soil gas component ratios and isotope analysis.
• Studying plume migration over time based on surface soil mineralisation patterns.

Strengths

• Includes a concrete total CO2 emission rate estimate of 649-1015 kgCO2/d.
• Describes two distinct sampling patterns (regular and irregular grids) for spatial mapping.
• Contains results from 16 installed soil gas wells for real-time analysis.
• Provides specific carbon-13 isotope values (-0.21‰ and -0.22‰) for source identification.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the single case study site in Qinghai, China.
