Energy industry has been drilling deeper, long horizontal, multi-lateral wells to tap deeper reservoirs to meet increased global energy demand. Challenging environment and drilling operation in new hydrocarbon reserves are often associated with high pressure and high temperature regime. The conventional biopolymers such as cellulose, starch and xanthan gum used in drilling fluids as viscosifiers, fluid-loss control additives and suspending agents degrade and deteriorate under high pressure and high temperature conditions. The study conducted by Dr Qinglin Wu’s group with support from USDA Forest Service and State of Louisiana shows cellulose nanomaterials extracted from trees exhibit excellent thermal and physiochemical properties due to their well-ordered crystalline structure. The utilization of these properties allows designing high performance water and oil-based drilling fluid systems. The LSU AgCenter holds one US Patent for cellulose nanomaterial-based drilling fluid technology,and a new patent application on cellulose nanomaterial fluid additive is being processed by the US Patent office.The developed fluid additive trade-named as TigerBullets Micro is currently being tested in Louisiana, Texas, and Alaska as environmentally friendly lost circulation control material.
