Modified hydroxyethyl cellulosic polymers for improved well bore fluids and related uses |
| abstract |
Described herein are methods of placing a downhole fluid that comprises an aqueous base fluid and a viscosifying agent that comprises a crosslinked borate-mHEC complex in a wellbore penetrating a subterranean formation. The viscosifying agents disclosed herein include those whereby modified hydroxyethyl cellulose is crosslinked with a borate crosslinking agent to form a complex that has sufficient viscosifying and suspension properties to enable the use of the complex their use in downhole fluids. |
