A drilling fluid prepared using two different types of clay was subjected to rotational viscometer test. The solid contents of fluid systems which provides 15 cp apparent viscosity at 600 ipm are listed in following Table: of clay X clay Y clay Solid content (by weight %) 8 P (Ibm/gal) Amount of clay (gr/350 ml) Yield (bbl/ton) 38 a) Calculate the density of drilling fluid prepared using these clays (lbm/gal) b) For the drilling fluid prepared using these clays, calculate the amount of clay (gr) required to add 350 fresh water c) Calculate the yield of drilling fluids prepared using these clays
