Ida, our chemical engineer, has just completed a thermodynamic pilot project carried out for TOTAL Denmark. She analysed and modelled two different production wells. In one well scaling mostly takes place in the vertical section immediately above the reservoir and in the other scaling takes place over an interval below and close to the well head.

Further, she found that the transition in pressure and temperature between “no scaling” and “high risk of scaling” is very slim – information that should be of great value to any operator dealing with production optimisation while managing costs for workovers. Saturation Index Plots helps E&P as well as geothermal operators assess the risk of scaling associated with a considered bean-up of a production well.
