Abstract

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

Highlights

  • Mud and filtration loss within the formation during drilling and completion operations, have direct effect on bore hole stability, the formation damage.Filtrate loss occurs in the high permeability formation where the drilling fluid filters through the wellbore and invades the formation

  • [1] Used three types of nanoparticales (Nickle, copper and Cobalt) to replace polymer additives in drilling fluids. They found that these additives lose their effectiveness at high temperatures and when small amount of these materials had been used, the mud exhibited excellent shearthinning behavior and stable rheological properties at high temperature.Jimet al.used two types of mud with two types of nano additives (Graphene oxide and carbon nano tube), they gained a good result on rheological properties but the fluid loss control still an issue with these fluids [3]

  • Matthew M. et al studied the effect of Fe2O3 nano particles, as fluid loss control additives, at different concentrations with two other additives; Iron oxide Clay Hybrid (ICH) and AluminoSilica Clay Hybrid (ASCH)
