Water-based commercial compound solutions with diluting by 2-5 times are used for work performance. This allows to increase injection volume and decrease unit cost per 1 m3 of the working solution. The system’s curing time is controlled by dilution – the compound is cured faster when there is less water.
Diluting value is determined by the pour point time required according to the geological and physical conditions of the reservoir, mainly by the temperature and injectivity properties.
Reinforcing fillers are added to the compound to increase adhesion and hardness of the compound, depending of the required result, like: requirements for isolation zone size, porosity & permeability properties of the reservoir, crossflow type.
Selective action in case of undiluted commercial compound since hardening occurs only upon water impact in water saturated portions of the reservoir.
The compound can be cured by water with any salinity value.
Full-scale curing and high chemical adhesion to the rocks. High isolating effect and ability to withstand high draw down pressures (more than 10 MPa).
Easy to prepare. Standard machinery is used for carrying out operations.
Low viscosity of working solutions and lack of solids in the compound allows to penetrate the low-permeable areas of the formation.
Possibility to use in other compounds as base agent for adding reinforcing fillers.
