Abstract
A wellbore treatment fluid containing lost circulation materials and methods for using the treatment fluid, the fluid including a carrier fluid and nano-carbohydrate based sheets. The sheets may be folded or rolled into various cross-sectional surface area reducing configurations. The nano-carbohydrate based sheets may contain cellulose and or chitin materials. A method for utilizing the treatment fluid for creation or maintenance of a well includes forming or providing the treatment fluid and introducing the treatment fluid into a borehole.
