Abstract

1. Process for the preparation of fluids based on aqueous saline, comprising a derivative of cellulose, having at least one hydroxyalkyl group per anhydroglucose unit, as an agent which confers viscosity, characterised in that a homogeneous paste comprising a cellulose derivative and a polyfunctional alcohol or one of its monoethers, is added to the aqueous saline solution, the weight ratio between the polyfunctional alcohol or one of its monoethers and the cellulose derivative being greater than 1.
