  1. Type of facility = heat, electricity, or combined heat-electricity, T prod. = production temperature, T inj. = injection temperature, Q prod. = production rate, p groundl. = ground-level pressure, p inj. = injection pressure. TVD = true vertical depth. Type of scales: cc = calcite, vat = vaterite, Fe-sulf. = iron sulfides, Cu-sulf. = copper sulfides
