PETROLEUM ENGINEERING LABORATORY GROUP D EXPERIMENT ON DENSITY ABSTRACT Density or mass density can be appropriately defined as the mass per unit volume of a material substance Density is represented using the character ρ It is a letter in the Greek alphabet called Rho However it is sometimes represented using the Latin letter D Density is obtained by dividing the mass of the substance by it s volume Mathematically represented below ρ m v Density is a very important property when it comes to drilling fluids The pressure exerted by a static pressure i e the hydrostatic pressure of the drilling fluid is dependent on the density of the drilling fluid Therefore the proper control of the density of the drilling fluid will in turn control the hydrostatic pressure The hydrostatic pressure of the drilling fluid has to be greater than the formation pressure in order to prevent the uncontrollable flow of formation fluids into the wellbore This experiment determines the density of two different samples of drilling fluids INTRODUCTION The starting point for drilling fluid pressure control is mud density The density of a substance is it s mass per unit volume It is represented with the Greek character Rho ρ The Density of a drilling fluid needs to be monitored closely and adjusted in order to control the pressure properties of the fluid to maintain wellbore stability In this experiment density is determined using a four scale mud balance It is a standout amongst the most delicate and exact field instruments accessible for deciding the thickness or weight per unit volume particular gravity of penetrating liquids
