There are several methods for creating nanoparticles, including both attrition and pyrolysis. The synthesis and application of nanoparticles is one of the most interesting filed of research from basic and applied point of views. The use of water-in-oil micro emulsions for the synthesis of nanoparticles is one of the most promising methods. For this work, nanoparticles for use as nanomud was prepared by mixing Nanographite and Nanosilicon wires. The composition of the nanomud was Bentonite (69%), Barite(19%), Starch (9%) and nano (3%).The normal mud was prepared by mixing Bentonite, Barite and starch in the proportions 70%, 20% and 10% by weight.
