This study aim to reduce mud filtrate while drilling oil wells, which cause a lot of problems that delay drilling operations and increase drilling cost and destroy the well productivity later, so we make a lot of experiments for reduce mud filtrate by effect on mud cake to make it have lower porosity and permeability as possible and make it resistance for filtration of mud through it.
So we benefit of industrial detritus such of used cars oil and the coke resultant of petroleum refinement and discern that the addition of these materials reduce permeability of mud cake and make it water averse subsequently reduce mud filtrate through it and reduce problems that caused by it.
