Chemical reagents

KEM NOBAC is used to prevent bacterial decomposition of organic drilling fluid components such as polysaccharides, is effective in controlling blue-green algae and microscopic fungi, and inhibits the activity of sulfate reducing bacteria that cause equipment corrosion. It is used to treat water injected into the reservoir to prevent the formation of biogenic hydrogen sulfide and carbon dioxide. It is also used to prevent biodegradation of drilling fluid components and prevent bio-contamination of formations during drilling. If hydrogen sulfide is present in the formation being drilled, it absorbs it.

KEM NOBAC is added to the drilling fluid when it is prepared after the polymers or clay powder have been introduced and completely dispersed. The concentration is at least 0.5 l/m3.

KEM NOBAC is packed in polypropylene barrels with a capacity of 200, 275 dm³, canisters 20−50 dm3.

KEM VIS is used as a structure builder in water-based drilling fluids, both fresh and highly saline. The reagent regulates rheological properties of drilling fluid, provides retention and carrying capacity, provides pseudoplastic character of rheological behavior of drilling fluid.

KEM VIS is used in concentrations from 0.25 to 4.5 kg/m3 depending on the application technology.

KEM VIS comes in multi-ply paper or polypropylene bags of 25 or 30 kg.

KEM PAC HV is used to effectively regulate rheological, filtration properties of water-based bentonite and biopolymer drilling fluids. It reduces filtration of muds of various salinities. Forms a thin, firm, low-permeability crust.

KEM PAC HV is used in concentrations from 0.05 to 5.0 kg/m3, depending on the viscosity and filtration of the drilling fluid required. The injection should be done carefully, stirring for at least 20 minutes.

KEM PAC LV low viscosity purified polyanionic cellulose, designed to regulate the filtration properties of the drilling fluid. It does not significantly affect rheological characteristics. It is used for decreasing water yield of drilling fluids of different salinity. Contributes to formation of a thin, dense, low-permeability filtration crust.

KEM PAC LV is used in concentrations from 0.05 to 5.0 kg/m3, depending on the desired drilling fluid filtration rate. The injection should be done carefully, stirring for at least 20 minutes.

KEM PAC LV is packed in open-mouth and closed-mouth (with valve) bags of 25 kg.

KEM SLIDE improves the lubricity of water-based drilling fluids, increases drilling speed, reduces the risk of "sticking", and reduces the friction coefficient of drilling equipment.

KEM SLIDE is used to treat fresh, slightly mineralized and inhibitory drilling fluids in volumes from 5 to 35 l/m3 by volume when drilling vertical, horizontal and directional wells.

KEM SLIDE упаковывают в стальные бочки вместимостью 200, 275 дм3, в полипропиленовые бочки вместимостью 200, 275 дм3, в канистры 20-50 дм3.

KEM DEFOAMER is used in water-based drilling fluids to reduce foaming and as an anti-foaming additive for chemical reagents. Defoamer is compatible with all chemicals used for chemical treatment of drilling fluids (filtrate reducers, fluidizers, flocculants, pH regulators, bactericides). It can be used as an additive to process fluids for perforating, killing and preserving.

KEM DEFOAMER is used for the treatment of fresh, slightly mineralized and inhibiting drilling fluids in the volume of 0.1 to 2 l/m3 by volume when drilling vertical, horizontal and directional wells.

KEM STAB MUD is used as a highly effective inhibitor of clay minerals, providing preservation of stability of the walls of the well, composed of unstable hygroscopic clay rocks, as well as reduction of the drilling fluid by increasing the carrying capacity by preventing dispersion of clay cuttings. It can be used as a polymer-silicate plug of perforated formations when installing a cement bridge, as well as in enhanced oil recovery technologies to regulate the coverage of the formation by flooding, increase the oil displacement ratio, redistribution of flows in the reservoir due to lower filtration-volumetric characteristics of permeable intervals, and involvement in the work of low-permeable zones.

KEM STAB MUD is used to treat fresh, slightly mineralized and inhibitory drilling fluids in the volume of 5 to 35 l/m3 by volume when drilling vertical, horizontal and directional wells.

KEM STAB MUD is packed in steel drums with a capacity of 200, 275 dm³, in polypropylene barrels with a capacity of 200, 275 dm³, canisters 20−50 dm3.
