Inorganic fouling in oilfields has resulted in millions of dollars of operating expenditure every year since the inception of offshore oil and gas drilling, where mineral scale deposition in tubing, flowlines and downhole equipment leads to significant production downtime. Calcium carbonate (CaCO₃) fouling is endemic in oilfield systems, as produced water containing both bicarbonate and calcium ions is prone to form precipitates as a result of pressure changes during production.The release of carbon dioxide gas from the aqueous phase prompts the evolution of carbonate resulting in a rise in pH and consequent precipitation.

The crystallization of sparingly soluble salt in multiphase system, involving mixing between oil and water fractions, is one of the major challenges encountered by the petroleum industry. The kinetics of scale formation in the bulk of the fluid in the presence of the oil phase is very important and has received little attention. Most of the studies that focused on dealing with the challenges of scale formation in the oil and gas industry have been directed towards the understanding, predictions and treatment based on results from single phase brine solution.

The formation of mineral scale is an undesirable phenomenon which is as a result of the disturbances in thermodynamics and chemical equilibria of the water system. CaCO₃ scale is one of the major flow challenges in the oil industry and the crystallization process starts from thermodynamically unstable hydrated form to anhydrous polymorphic stable forms^1,2 The transformation involves a series of ordering, dehydration, and crystallization processes, each lowering the enthalpy of the system where the crystallization of the dehydrated amorphous material lowers the enthalpy the most. There are two theories regarding the polymorphic transformation of a solid structure. The first suggests the transformation occurs through a direct solid transition in which the metastable phase exhibits a rearrangement of its molecules or atoms to a more stable form³. The second is valid in the presence of a solvent which allows the dissolution and the re-nucleation and growth of the stable phase⁴.
