Heatmap displaying the top 30 most abundant families across all shale formations. Samples from different wells are indicated with separations within the facets. Annotations indicate the time of the sampling in a range of days after hydraulic fracturing and the salinity level following these categories saline (2000–10,000 mg/L), highly saline (10,000–60,000 mg/L) and brine (over 60,000 mg/L))
