Table 5: Base mud formulations: DF/BF1B, DF/BFBF and Nano DF/RPGBF bentonite added to samples after NaOH; DF, DF/BF, Nano DF/RPF, Nano DF, Nano DF/RPG and Nano DF/RPT bentonite added to samples at last (Distinct difference between Nano DF/RPG and Nano DF/RPGF by adding bentonite). Bentonite is added to Nano DF/RPG as the last additive, but in case of Nano DF/RPGF, bentonite is added initially.
