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

Inhibition of Barite Scale in the Presence Of Hydrate Inhibitors

SPE International Symposium on Oilfield Scale, 2004
Abstract Large volumes of hydrate inhibitors (e.g., methanol, ethanol, monoethylene glycol, and triethylene glycol as cosolvent) are added to control hydrate formation. Such practice has an adverse effect on scale formation since the mineral salts are generally less soluble in the cosolvent.

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.

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).

Well Stimulations and Scale Inhibitors

Permian Basin Oil and Gas Recovery Conference, 1988
ABSTRACT Three major well or reservoir stimulation methods or techniques are concerned with scale inhibitor applications: Acidizing. Fracturing. Acid Fracturing. Scale inhibitors are frequently used during these three types of well and/or reservoir stimulation jobs. The main objective for the use of

Development of Scale Inhibitors

CORROSION 1996, 1996
Abstract During the last fifty years, scale inhibition has gone from an art to a science. Scale inhibition has changed from simple pH adjustment to the use of optimized dose of designer polymers from multiple monomers. The water-treatment industry faces many challenges due to the need to conserve water, availability of only low quality ...

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.

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.

Development of an Ecofriendly Scale Inhibitor for Harsh Scaling Environments

Proceedings of SPE International Symposium on Oilfield Chemistry, 2001
Abstract The recent advances in drilling and completion technology have led to the development of more complex reservoirs including high pressure, high temperature, and high salinity (HP/HT/HS) fields. A combination of high calcium and barium concentrations in the produced water, coupled to high reservoir temperatures presents a ...
