It is an elastic lightweight cement system that allows you to create cement stone with modified elasticity properties. By changing the Young modulus and Poisson’s Cement Stone Coefficient, it is possible to achieve increased resistance of the cement stone to multiple cyclic loads, as well as to increase the overall index of possible impact loads.
It is an elastic cement system of normal density that allows you to create cement stone with modified elasticity properties, provide an improvement of cementing oil and gas wells, especially during multi-stage hydraulic fracturing operations. It is higher resistant to fracture due to changes in Young’s modulus and Poisson’s ratio.
The lightweight cement system is specially developed for cementing wells in permafrost rocks conditions and effectively solves the problems associated with these conditions, namely: interstring space leakage, thawing of rocks – an increase in the well diameter, cavitation, migration of gases and fluids – formation of channels / mud springs, absorption
This is a cement system that allows high-quality cementing of well sections located in the permafrost zone. The cement stone of this system has an accelerated growth of strength even at low temperatures. The system has lower heat production during hydration, which prevents rocks thawing and increasing the diameter of the open hole
It is a cement system that allows cementing of well sections with a high probability of cross-flows. Such intervals are often prone to the formation of channels in the cement stone, which subsequently leads to a shutdown of the mining process and repair and isolation squeeze.
It is a cement system that allows the creation of lightweight cement slurries with cement stone with increased early and final strength. The Light 60 system allows you to achieve a reduction of the WOC time and prevent borehole annulus
It is an ultra-lightweight cement system that allows the creation of cement stone with increased early and final strength. The LightCem Ultra system helps to reduce the risk of hydraulic fracturing due to low hydraulic fracturing ratio, to perform cementing in one stage avoiding the use of a stage collar in the casing set
This is a stabilized expanding plugging cement made on the basis of Portland cements, active polydisperse siliceous additives and expanding components. If necessary, fluid loss indicators, rheological parameters can be modified, reinforcing properties can be added etc.
This is a cement system that allows cementing of well sections at temperatures above 110 ° C. Within high temperatures, traditional Portland cements are susceptible to strength regression and destruction of the cement stone structure. The TNS system, due to special inorganic additives, is resistant to this effect.
This is a cement system that allows you to create a reliable barrier when cementing steam injection wells, where the temperature of the working agent exceeds 300 ° C. The unique composition allows it to withstand cyclic temperature loads, preventing cracking and, as a result, a leakageof the annulus.
This is a cement system that allows cementing well sections in an aggressive, corrosive environment. This system counteracts the destruction of cement stone during hydrogen sulfide and carbon dioxide exposure, thereby preventing regression of the cement stone and ensuring the tightness of the productive horizon.
