WellFix Spacer SB-1 is designed for use in the petroleum and gas industry, in the processes of well construction and workover, as an additive preventing sedimentation of solid particles. It creates homogenous structure throughout the total height of cement column. It has excellent rheological properties, increasing the dynamic yield stress, not affecting the plastic viscosity at that. WellFix Spacer SB-1 positively affects the filtration rate. It is efficient in the fresh water and the salt-saturated systems. It is compatible with all types of surfactants and detergent compositions.
WellFix Spacer SB-1 is recommended for use in solutions with low density, in the systems on the basis of microcement, as well as in spacer washer fluids to impart the required rheology properties to them. It is indispensable in the process of cementing of the intermediate and the production casing, especially in the wells with horizontal completion.
WellFix Spacer SB-1 is recommended as an anti-sedimentation agent for cements of various densities – from 0.05 to 0.3% of dry cement weight.
Recommended concentration of WellFix Spacer SB-1 for heavyweight separation spacers with density of 1.3 gr/cm to 3.5% of the water mass.
