N2  - Several borehole problems are encountered during drilling a well due to improper mud design. These problems are directly associated with the rheological and filtration properties of the fluid used during drilling. Thus, it is important to investigate the mud rheological and filtration characteristics of water-based drilling muds (WBMs). Several materials have been examined but due to the higher temperature conditions of wells, such materials have degraded and lost their primary functions. In this research, an attempt was made to prepare a water-based mud by utilizing graphene nano platelets (GNP) in addition to the native tapioca starch at different ratios. The combined effect of starch and graphene nano platelets has been investigated in terms of mudâ??s rheological and filtration parameters, including its plastic viscosity (PV), yield point (YP), fluid loss volume (FLV) and filtercake thickness (FCT). The morphological changes in the filtercake have also been observed using Field Emission Scanning Electron Microscope (FESEM) micrographs. Plastic viscosity was increased from 18â??35 cP, 22â??31 cP and 21â??28 cP for 68â?¦F, 250â?¦F and 300â?¦F, respectively. The yield point was also enhanced from 22â??37 lb/100ft2, 26â??41 lb/100ft2 and 24â??31 lb/100ft2 at the studied range. The fluid loss was dramatically reduced from 14.5â??6.5 mL, 17.3â??7.5 mL and 36â??9.5 mL at 68â?¦F, 250â?¦F and 300â?¦F respectively. Similarly, filtercake thickness was also reduced which was further illustrated by filtercake morphology. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.
