The minimisation of mineral scale formation within oil and gas installations is a major challenge. Both surface deposition and bulk precipitation have been widely studied separately using a variety of methods. However, only limited research has focused on both processes at the same time. This paper presents the design and optimisation of a relatively new technique to study both processes at the same time.A new in-situ rig has been designed to perform deposition tests in flowing conditions and allows real time measurements to be made. The experimental procedure associated with the rig has been optimised to obtain reproducible results of turbidity and surface coverage measurements. The surface and bulk scale formation kinetics have been evaluated using quantification of the surface coverage in real-time, enabling for the first time a surface growth rate to be evaluated and compared with the corresponding bulk crystallisation kinetics.the initial results from this will be reported and discussed.
