Lab Report: DRILLING FLUID (MUD) DENSITY Objective: The aim of this experiment is to determine the mud density‚ specific gravity and hydrostatic pressure gradient for water-based-mud‚ WBM (Drilling fluid) using the OFITE mud balance. Theory: Drilling fluids are used during the drilling of boreholes‚ either for oil wells or water boles holes. One of the major functions of a drilling fluid includes providing hydrostatic pressure to prevent formation fluids from entering the wellbore. To ensure

slope‚ which could give the density value. The calculation of significant figures was one of the key objectives in this lab as well. Significant figures are essential to interpreting data because they allow for increased precision and accuracy. Also‚ using Excel‚ the density calculations could be performed quickly and accurately. In this experiment‚ the density of water was found by collecting the masses known‚ which was volumes of water. To determine what the unknown density is‚ the mass should be divided

hydrometer is an instrument to measure the relative density of liquids. It consists of a tube with a bulb at one end. Lead shots are placed in the bulb to weigh it down and enable the hydrometer to float vertically in the liquid. In a liquid of lesser density‚ a greater volume of liquid must be displaced for the buoyant force to equal to the weight of the hydrometer so it sinks lower. Hydrometer floats higher in a liquid of higher density. Density is measured in the unit of g cm-3. 4. SHIP

Jashandeep Gill Gammellos Chemistry Density is one of the fundamental principles of physics. Density is the reason why a plank of wood floats on water while a piece of metal several times smaller will sink. Density of an object is measured in g/cm³ or g/cc. The equation is D=M/V‚ D being the density of the object‚ M being the mass of the object‚ and V being the volume of the object. Mass is the space an object takes up. It is the amount of matter present in an object. Mass is measured using
