Starch is typically applied in drilling fluids technology by customized forms because of its solubility in water.
They are principally applied to diminish the filtration of virtually all types of water based drilling fluids, owing to their swelling ability.
This swelling assortment diminishes muds permeability, decreases the mud filterability and hence causing fluid loss on borehole areas.
There is an opportunity of filtration management by appropriate consumption of starch ingredients and their combination with polymers and bentonite [6], [7].
Among the most commonly used filtration control agents reported are biopolymers, synthetic polymers and sodium bentonite [8].
