Described herein is a beta-glucan material comprising 1,3-1,6 beta-glucan which upon dissolution achieves a range of 1 to 2, preferably 1 to 1.5 Filterability ratio and viscosity ratio ranging from 1.5 to 4. The solubilized beta-glucan material has viscosity-increasing and filterability properties required for EOR applications. |
