The scaling potential of the Miller field has been calculated using an aqueous modeling package. Calcium carbonate scale is predicted on producing Miller formation water and a severe barium sulphate scale problem can be expected on sea water breakthrough into producing wells.

A strategy to evaluate commercially available scale inhibitors for the Miller system is presented using static scale precipitation and dynamic tube blocking experiments. The scale inhibitor squeeze technique to deploy scale inhibitors into the reservoir is described. The use of computer modeling to optimise the scale inhibitor treatment in terms of chemical required and treatment lifetimes is discussed.
