Abstract (2. Language): 
This paper deals with the properties and use of drilling fluids which are used for aiding the drilling of borehole into the earth along with the process of development of properties of a local soil called ‘Dhaka clay’ in order to use as a drilling fluid. Here the most commonly used drilling fluid named as ‘bentonite’ slurry is addressed with its properties and functions involving standard laboratory investigation. Then a distinguish between the determined properties of collected Bentonite sample from local market and properties determined by previous scholars has been demonstrated which leads to a decision that local bentonite clay doesn’t meet desired qualities of drilling fluids physically and economically. However, properties of local soil known as Dhaka Clay were also investigated in the laboratory to compare with normal bentonite sample. The results provide some supports to introduce the use of local soil as drilling fluids. After that, a special test was conducted to develop the local soil as a drilling fluid by means of separating finer portion of the particles from Dhaka Clay which eventually justifies the suitability of this finer potion of Dhaka clay for using as a drilling fluid.
