The role of the mud engineer or more properly drilling fluids engineer is very critical to the entire drilling operation because even small problems with mud can stop the whole operations on the rig. So, the basic parameters which effect on the properties of drilling fluid are discussed in this paper. The sulfur removal from drilling fluid for prevention of corrosion is studied, specially. According to the results, higher initial pH =8 shows the small changes in final pH during 14 hours from 5 to 19 hours. For initial pH=7 the trend of final pH is also approximately smooth from 9 hr to 19 hours, but from 5 to 9 it shows a minimum amount of 7 for pH after 7 hr. Also, the changes in pH values make different stability behavior in the suspension. The optimum value of pH seems to be 8 and the best concentration of ZnO is 3 gr/lit which lead to effective coagulation and flocculation. The experimental results show, if time duration will change from 5 to 25 hours the trend of pH for 1 gr/lit of ZnO nanoparticle will vary from 10.53 to 10.36. In addition, this factor after 21 hours will be 104, approximately. So, in this concentration the coagulation reactions seem not to be completed and continue even after 25 hrs.
