Abstract:
The present invention relates to a method which allows quick and effective hydration of associative polymers, in particular those intended for use in the field of oil drilling. This method uses a specific solid formulation, which can be easily hydrated, including, in a pre-mixture, said associative polymers and surfactants capable of improving the hydration of these polymers.
