During the drilling of oil wells, sometimes the digging drill passes through layers with coarse porosity which causes drilling mud loss. Concerning the preciousness of drilling mud, preventing its loss can be economically efficient and lead to a desirable drilling which increases productivity of the oil well. Due to the invaluable of the pores in different ground strata for Hydrocarbon material extraction purposes, a blocker should be used to prevent drilling mud loss. Magnetite Cement is used for this purpose.
