Patent

CA 2420170

A drilling fluid additive is provided wherein the additive is manufactured by a method comprised of admixing colloidal solids such as talc with at least one carrier such as an oil or glycol to create a suspended mixture to thereby allow the colloidal solids to be pre-wet with the carrier; and then admixing copolymer beads to the suspended mixture.

L'invention concerne un additif de fluide de forage où l'additif est fabriqué selon une méthode comprenant le mélange de particules colloïdales solides comme du talc avec au moins un agent porteur comme de l'huile ou de l'éthylèneglycol pour créer un mélange en suspension afin de permettre aux particules colloïdales solides d'être pré-humidifiées avec l'agent porteur, puis mélanger des perles de copolymère au mélange en suspension.
