Abstract

Effectiveness of lignocellulose nanomaterials and polyanionic cellulose (PAC) on microstructure, rheology, filtration, and salt tolerance performance of bentonite (BT) water-based fluid under two saline conditions (NaCl and CaCl2) was studied. The fluid with cellulose nanocrystals (CNCs) and nanofibrillated cellulose (NFC) exhibited salt-dependent increase in rheological properties. However, the fluid with lignin-containing NFC (LNFC) showed only minor reduction in yield stress and gelation behavior with improved filter cake properties. All CNC-, NFC-, and LNFC-BT fluids showed an increase in filtration losses with added salt ions. Adding PAC enhanced salt tolerance for the fluids, mainly in the NaCl-added system.
