Predictions and workover findings revealed that sulphate and carbonate scale problems have a significant impact ·on the Glamis field production. Scale predictions closely agreed with the findings. An estimation of the rate factors governing the kinetics of calcium carbonate have been made. Specific treatment facilities, permitting downhole injection and inhibitor squeezing were incorporated into the designs of the recompleted satellite wells to combat the two scaling mechanisms.
