Method for the combined application of scale remover and inhibitor

A method comprising:

• preparing a scale remover solution;
• preparing a scale inhibitor squeeze solution;
• mixing the scale remover solution and the scale inhibitor squeeze solution, to thereby form a mixture;
• and
• injecting the mixture into a reservoir at a temperature of 60° C., using water produced from a well, with a calcium content ranging from 2,080 to 20,000 mg/L, to provide simultaneously removal of scale followed by inhibition of scale from and on reservoir rock.
