(EN) HIGHLY BRANCHED POLYMERIC MATERIALS AS COATING ON WEIGHTING AGENTS
(FR) MATÉRIAUX POLYMÈRES FORTEMENT RAMIFIÉS EN TANT QUE REVÊTEMENT D'AGENTS ALOURDISSANTS
Abstract
(EN)
A wellbore fluid having at least two phases, the wellbore fluid including a fluid phase; and a solid phase including a powdered solid material coated with a polymer, wherein the polymer is the reaction product of a polyesteramide and a crosslinking agent is disclosed.
(FR)
L'invention concerne un fluide de puits de forage doté d'au moins deux phases, le fluide de puits de forage incluant une phase liquide et une phase solide incluant un matériau solide en poudre revêtu d'un polymère, le polymère étant le produit de réaction d'un polyesteramide et d'un agent de réticulation.
