Acid Corrosion Inhibitors and Intensifiers

By nature of its adsorption on solid surfaces, the corrosion inhibitor is a surface-active agent with a unique purpose; to protect pipe rather than to change acid behavior in the formation. Corrosion inhibitors do not stop corrosion; they greatly reduce the reaction rate of acid with steel. Proper selection and application of corrosion inhibitors also reduce pitting (the tendency of acid to corrode or dissolve metal deeply in specific sites). Corrosion inhibitors are cationic and oil wetter’s. This is the mechanism by which they adsorb on a metal surface and form an oil-wet film to protect the iron from exposure to acid. Plating out and oil wetting also occur in the formation, especially on clay minerals. To compensate for this, other additives, such as surfactants and mutual solvents, are used to restore water-wetness and maximize permeability to oil.

Cenosphere

Summary
In the oil and gas industry aluminosilicate microspheres are used as an additive in drilling mud when drilling wells for various purposes. It can be used also in construction industry for the manufacture of ultra-light and aerated concrete or be applicated in as insulation materials or composite materials.Hollow ceramic spheres are efficient, lightweight additives that can be used in most all latex, thermoset resin and cement-based products. When Hollow ceramic spheres replace heavier, more expensive components on an equivalent volume basis, they can reduce raw material costs as well as density. All ceramic spheres may be treated by an exclusive process which modifies their surface to allow easier dispersion and improved physical properties in specialized applications such as sheet molding and bulk molding compounds. BSG and BCG are standard, relatively large-sized grades. They are recommended for use in cements, grouts, sealants, roofing and flooring materials.

UPC-U80S can be used together with medium temperature retarder (UPC-U21L).

Dispersants

The product is a kind of sulfonated aldehyde-ketone condensation polymer dispersants. It can significantly reduce cement consistency and improve rheological behavior of the cement slurry through restraining the coalescence between the cement particles by the steric hindrance Of the large molecule. The product has no adverse effect on fluid loss, settling stabilization, free liquid, thickening time and strength developing.

Anti-Gas Migration

Summary

Gas migration can have an adverse effect on slurries used in front of gas formations. Our liquid latex anti-gas migration additives can block gas from moving through the cement slurry and can do so in wells up to 160°C.Slurry design is one part of the strategy to control gas migration, however many other job design aspects such as effective mud removal, must also be considered.

Cement Extenders Spacers and Chemical Wash

Summary

The efficient removal of drilling fluids is essential to successful cementing operations. Mud remaining on pipe or formation surfaces, or present as channels through the cement commonly cause loss of isolation of permeable zones under different pressures. The well bore must be cleared to remove drilling fluids and leave surfaces water wet. This in turn leads to a good cement bond.

Water Treatment Chemicals in Kuwait

Higher vitality cost, diminished effectiveness, costly tedious incessant fixes and substitution of gear are altogether aftereffects of scale collection and forceful assaults by cooling water, in the event that it is left inadequately treated for erosion control, consumption, scaling, fouling are the serious issues in cooling water frameworks that can harm the whole framework. The essential target of cooling water treatment is to keep up a superior warmth move effectiveness of cooling framework conferring assurance to the entire plant from erosion and decimation. This consumption issue turns out to be so serious particularly when neighborhood water is utilized for cooling framework because of the incredibly assaulting nature of nearby water. Developing an appropriate water treatment framework especially reasonable for Gulf water is finished through the joint work of Kuwait Institute for Scientific Research and UNIVERSAL PROJECTS KUWAIT, so as to serve the clients around, in a generally logical and practical way. Broad research and field-test by a group of research laborers brought about the improvement of these scope of items. The correct answer for a basic issue of consumption control.
