The effect of pressure on CaCO{sub 3}(s) ``scale`` formation is dealt with from a thermodynamic perspective. The necessary equations are developed for the situation where a gas phase exists and where it doesn`t. For any given brine the input data required are: temperature; pressure of CO{sub 2} (if gas phase present); total pressure; Ca{sup 2+} concentration; HCO{sub 3}{sup {minus}} concentration; concentrations of other ions; and presence or absence of gas phase. A computer program then calculates the appropriate equilibrium constants and activity coefficients. It can then predict whether CaCO{sub 3}(s) will form and in what quantity.
