The intent of this study was to determine solubility of
barium sulphate scale from mixing synthetic brines (formation
water and sea waters) at various temperatures 40 to 90
°C. For each experiment of barium sulphate scale, 100 mL of
each filtered opposite waters were poured simultaneously into
a beaker. The synthetic brines were heated on hot plate and
the solution was stirred by magnetic stirrer and after that the
solution was filtered through 0.45-
