The objective of this project is to use a smart nano drilling fluid which is

prepared using nano size bentonite clay which has an enhancement of its rheological

properties of the mud especially quick plastering of the wall of the wellbore based on

the efficient filtrate loss control into the high porous and high permeable formation.

The appreciable enhancement in the filtrate loss control properties is

expected by using thus smart nano drilling fluid as compared to the conventional

water based mu
