Severe scaling conditions exist in South Brae because of the high barium content of formation water and low pH downhole. Formation water is also susceptible to calcium carbonate scaling. This paper presents experiences with scale control on topsides and down-hole during field development. Topsides control has been achieved at the expense of high dose rates and secondary effects on produced-water quality. A sulfonate-based inhibitor was developed and applied for downhole control of BaSO[sub 4]. This paper presents the benefits achieved by the use of desulfated seawater to minimize the BaSO[sub 4] potential and describes the methods developed to control calcium carbonate scale.
