One of the most important factors that cause formation damage is drilling fluidinvasion caused by mud filtration. Hence, it is essential to minimize the mud filtration inorder to reduce its damage to the formation using drilling fluid additives that control andminimize the filtration rate. Magnesium Oxide (MgO) nanoparticles at different masses(0.01, 0.05, 0.07, 0.1, and 0.2) gm with water base mud have been investigated in thisresearch to measure its effect on the filtration rate. Four types of drilling fluid are used inthis research; API water base mud WBM, Saturated salt water mud, DURA THERM mudand polymer mud. Filtration rate was tested under high temperature high pressure (HTHP)conditions; at (75 and 100) C and (500 psi), and at room temperature and pressure at (100psi). The viscosity of all drilling fluid types is measured using a rotational viscometer atroom temperature and atmospheric pressure. In general, the results showed that addingMgO nano particle helped in reducing the filtration rate of drilling fluid, the best resultswere gained in DURA THERM mud and Saturated Salt Water Mud at MgOconcentrationof 0.07gm and 0.2gm, respectively; where the filtrate reduction 60% at 100C. Also, MgO addition improves rheological properties and drilling fluid stability
