Scale-inhibitor (SI) squeeze treatments will protect the well if the concentration in the produced brine is above a certain concentration, known as the minimum inhibitor concentration. It is generally accepted that retention level is governed by adsorption and precipitation mechanisms. Recent experiments concluded that adsorption is more dominant than precipitation at low concentrations. To detect surface deposits occurring when the SI retention is governed by an adsorption and adsorption/precipitation regime, high-resolution X-ray computed tomography (CT) scanning was used in an in-house-built minicoreflood system.
