Title
(EN) SOLUBLE & FILTERABLE BIOPOLYMER SOLIDS
(FR) SOLIDES BIOPOLYMÈRES SOLUBLES ET FILTRABLES
Abstract
(EN)
Described herein is a beta glucan material, comprising 1,3-1,6 beta glucan, that when solubilized achieves a filterability ratio ranging from 1 to 2, preferably 1 to 1.5, and a viscosity ratio ranging from 1.5 to 4. The solubilized beta glucan materials has desired viscosity build and filterability property for EOR applications.

L'invention concerne un matériau de bêta-glucane, comprenant du 1,3-1,6-bêta-glucane, qui, lorsqu'il est solubilisé, atteint un rapport de filtrabilité compris entre 1 et 2, de préférence entre 1 et 1,5, et un rapport de viscosité compris entre 1,5 et 4. Les matériaux de bêta-glucane solubilisés présentent des propriétés souhaitées de filtrabilité et d'accroissement de la viscosité pour des applications de récupération assistée du pétrole.
