Scale-driving parameters at reservoir pressure (black bars: simulation point 1 (according to Fig. 1)), at standardized wellhead pressure at 5 bar (red bars: simulation point 5), and at real wellhead pressure at 5–14 bar (blue bars: simulation point 5). X-axis shows site number. a total pressure, b logarithmic partial pressure of \(\hbox {CO}_2\), c pH,\(\hbox {SI}_{{calcite}}\), e temperature, f sum of free gas phase, g calcium ion concentration, h calcium ion activity, i bicarbonate ion concentration, k bicarbonate ion activity
