Synthesis of New Phosphate and the Evaluation as Scale Inhibitor in Oilfield

Key Engineering Materials, 2019
Compared with inorganic phosphonates, organic phosphonates have better chemical stability in water treatment, and are not easy to hydrolyze in higher temperature and wider pH range.

Experimental Investigation of the Interaction between a Phosphate Ester Scale Inhibitor and Carbonate Rocks for Application in Squeeze Treatments

Energy & Fuels, 2019
Studying the interaction between scale inhibitors (SIs) and chemically reactive carbonate minerals is crucial for determining SI retention in “squeeze” treatments.

New Method for Scale Inhibitor Testing

SPE International Symposium on Oilfield Chemistry, 2009
Abstract During qualification of scale inhibitors for the Ormen Lange project, it was discovered that the dynamic tube blocking (DTB) test could not simulate the scaling conditions good enough for gas/condensate subsea fields which will be using pH stabilised MEG for hydrate control.

Synthesis, Characterization, and Application of a Multifunctional Cellulose Derivative as an Environmentally Friendly Corrosion and Scale Inhibitor in Simulated Cooling Water Systems

Industrial & Engineering Chemistry Research, 2018
A borated aminated cellulose citrate (BACC) inhibitor was synthesized from bagasse cellulose with citric acid, diethanolamine, and boric acid by mechanical activation-assisted solid-phase reaction (MASPR) technology. The BACC was characterized using FTIR,

Scale Inhibitors for Geothermal Applications

SPE International Conference on Oilfield Scale, 2012
AbstractSiliceous scaling deposition from geothermal brine is recognized as detrimental to the smooth operation of steam generation and injection facilities; the control of such deposition is costy and less well understood. Scales normally encountered in geothermal wells are often different from the conventional cases.

An Evaluation of Scale Inhibitors

Journal of Petroleum Technology, 1972
A rating of inhibitors in the order of their effectiveness is a relative matter and depends upon test conditions. The most important conditions are the degree of supersaturation and the temperature; the higher the supersaturation and the higher the temperature the less effective a scale inhibitor becomes.

Acrolein Based Polymers as Scale Inhibitors

CORROSION 1998, 1998
Abstract Polymers are widely used to prevent scaling in various applications. Whilst acrylic acid and maleic acid are often used for homo and copolymers, acrolein is unique as a monomer for polymeric scale inhibitors. The polymerization can be carried out by using hydrogen peroxide as a polymerization initiator.

Laboratory Evaluation and Mechanistic Understanding of the Impact of Ferric Species on Oilfield Scale Inhibitor Performance

Energy & Fuels, 2018
Scale inhibitor chemicals are widely used in oilfield operations for mineral scale control. However, the presence of iron species in oilfield produced water can considerably impair the performance of scale inhibitors.

Evaluating chemical-scale-inhibitor performance in external magnetic fields using a dynamic scale loop

Journal of Petroleum Science and Engineering, 2019
Monoethylene glycol (MEG) is extensively used in oil and gas pipelines to prevent the formation of gas hydrates. However, the injection of MEG may inadvertently contribute to mineral-ion precipitation through reduced solubility of ionic species and ...
