Potential kinetic model for scaling and scale inhibition mechanism

Desalination, 2016
Abstract Scale deposition occurs when dissolved salts precipitate from aqueous solution. Scale formation is reported to occur by two pathways, surface crystallization & bulk crystallization. Scaling in pipe system is a combination of these two mechanisms and is affected by process conditions in the pipe.

Mechanisms of Mineral Scale Inhibition

SPE Production & Facilities, 2002
SummaryAn extensive study of adsorption and desorption isotherms of four phosphonates on barite or calcite are tested for a wide range of solution conditions (0 to 1 M NaCl, 0 to 0.1 M Ca, 0 to 0.33 M sulfate, and 4.6 to 6.4 pH). From these adsorption/desorption observations, it is proposed that the primary driving force for adsorption is related to ...

Scale Inhibition in Wellbores

Proceedings of University of Tulsa Centennial Petroleum Engineering Symposium, 1994
Abstract Adsorption is considered the primary mechanism of scale inhibitor retention during squeeze treatments of sandstone formations. Steps are often taken to avoid inhibitor precipitation for fear of formation damage. In limestone and dolomite formations, phosphonic acid inhibitors are deliberately allowed to react with the formation ...

Combined Scale Removal and Scale Inhibition Treatments

International Symposium on Oilfield Scale, 2000
Abstract Calcium carbonate scale impacts oil production in a large number of fields worldwide. This scale is generally managed by acid washing to removal the scale and/or by performing scale inhibition treatments. The choice between inhibition and regular stimulation is cost driven, with high cost operations generally selecting ...

Scale inhibition study by turbidity measurement

Journal of Colloid and Interface Science, 2005
The concept of a critical supersaturation ratio (CSSR) has been used to characterize the effectiveness of different types of scale inhibitors, inhibitor concentration, and precipitating solution pH in order to prevent the formation of barium sulfate scale.

Inhibition Mechanisms for Sulphide Scales

SPE International Symposium and Exhibition on Formation Damage Control, 2008
Abstract Sulphide scales have over recent years become increasingly common in many oil and gas producing regions. The main sulphide scales are iron, zinc and lead, with the latter two often occurring together. This paper presents experimental results from a series of static iron sulphide (FeS) inhibition efficiency tests using 2 scale ...

The threshold scale inhibition phenomenon

Desalination, 1979
Abstract The precipitation of calcium carbonate has been studied in the absence and presence of hydroxyethylidene-1, 1-diphosphonic acid (HEDP). At ambient temperatures, a stable, threshold inhibited solution of calcium carbonate can be made in the presence of HEDP.
