A Way Beyond Scale Inhibitors – Extending Scale Inhibitor Squeeze Life through Bridging

International Symposium on Oilfield Scale, 2003
Abstract The Heidrun Field is located in the Haltenbanken area offshore Mid-Norway. The reservoir temperature is 85 – 88 °C and the reservoir pressure is close to hydrostatic pressure, around 250 bar. Seawater injection is utilized to increase recovery and for pressure support.

Metal Sulfide Scale Inhibitors

CORROSION 2020, 2020
Abstract Metal sulfide mineral scaling, fouling and deposition are frequently encountered problems in geothermal systems. Their formation, crystallization and deposition occur principally because of their extremely low solubility, based on the low solubility product (Ksp).

Can Green Scale Inhibitors Replace Phosphonate Scale Inhibitors?: Carbonate Coreflooding Experiments

Petroleum Science and Technology, 2009
Abstract The oil industry is currently facing severe restrictions concerning the discharge of oilfield chemicals into the environment. The purpose of this study is to test the possibility of replacing an organic phosphonate scale inhibitor (DETPMP) by a more environmentally friendly “green” species: carboxymethyl inulin (CMI). Although, promising these

Encapsulated Scale Inhibitor Treatment

Middle East Oil Show and Conference, 1997
Abstract Scale formation and deposition (CaCO3) in production facilities is a problem encountered in the Ghawar Field in Saudi Arabia. The scale deposition causes production loss and safety hazards. Downhole scale inhibitor squeeze treatments have proven successful in controlling this scale accumulation.

Effect of pH on the efficiency of sodium hexametaphosphate as calcium carbonate scale inhibitor at high temperature and high pressure

, 2020
Calcium carbonate (CaCO3) scale deposition causes serious issues in industries which deal with water, and its formation reaction is pH-depending. This study investigated the efficiency of sodium hexametaphosphate (SHMP) as scale inhibitor for calcium ...

Synthesis and evaluation of a new scale inhibitor: the modified epoxysuccinic acid copolymer

Journal of Dispersion Science and Technology
Polyepoxysuccinic acid (PESA) scale inhibitor is widely recognized as a green and environmentally friendly scale inhibitor. However, its functional group type is single and cannot be used for a variety of scales.

Novel polyacrylamide-based solid scale inhibitor

Journal of Hazardous Materials, 2017
Novel solid-state phosphorus-containing polymer was synthesized, characterized and investigated as anti-scaling agent for the removal of alkaline earth metals ions from water. An optimization protocol for the sorption process of the metal ions on the polymer surface was proposed and executed.

Modeling Scale Formation and Optimizing Scale-Inhibitor Dosages

IDA Journal of Desalination and Water Reuse, 2011
AbstractBecause of its reliance on simple indices for scale prediction, inhibitor selection, and dosage estimation, water chemistry design and treatment software currently used for membrane systems is not always adequate for the rigors of high-recovery systems.

Synthesis and Application of CCQDs as a Novel Type of Environmentally Friendly Scale Inhibitor.

ACS Applied Materials and Interfaces, 2019
Carbon quantum dots (CQDs) are promising nanomaterials since they have smaller particle size, excellent biocompatibility, and low toxicity. However, no  one has found their high-scale inhibition performance so far.
