W1 : Density of first material. High pH is also favourable for many organic viscosity control additives. A new field viscometer, capable of measuring viscosity at shear rates of 0. During drilling operations, control of sub surface pressure is of utmost importance. The effect of shear rate on dynamic barite sag, for invert-emulsion muds, has been studied and quantified using new and advanced technology. However, their thermal limitation is somewhat reduced. Arithmetic mean, Confidence interval, Deviation 963 Words 6 Pages Period 0 Density Lab Purpose The purpose of the lab is to find out the density of stoppers, the density of a 100% sucrose solution, and to figure out the density and the percentage of sucrose in the unknown solution.

In general, after the experiment was seen how properties such as viscosity, density, shear, yield point and pH are very important to understand the behaviour of the fluids in the formation and how to be able to control them in order to obtain the economics results that are aimed. However, contributing factors such as gravitational force will cause the weighting material particles to settle out of the suspension. The lid was then removed from the mud cup and the clean dry cup was then filled to the top with the mud sample to be tested. The character of the solid phase is tested to determine solids concentration, specific densities, and particle sizes. The pH meter is the most accurate method of measuring pH.

This paper summarizes an effort, ongoing for the last eight years, to develop a predictive theory of mudcake buildup and filtrate invasion practical enough to be utilized in everyday drilling operations. Low gravity solids have an average specific gravity of 2. . They are, without a doubt, the least difficult of the water muds to maintain. Replace the lid and wipe dry. The slope of the graph of mass against volume was 1.

To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. Wash or wipe the mud on the exterior of the cup. These properties are specifically designed for. List any five 5 very important functions of the drilling fluid? The Gel strength can be determined at a low shear stress after it has been allowed to thicken for an amount of time typically about ten minutes. However, inevitably the action of drilling the hole in a consolidated formation relieves stress.

Hypothesis: I think the chocolate bar will gradually decrease in density as it gets smaller. As we had our final solution of banana oil, we used the I. There is no reliable visual method of determining the density of drilling mud, the mud balance is the most reliable and simple way of making the determination. Chemistry, Density, Liquid 1167 Words 4 Pages Unknown Code: K General Chemistry Laboratory September 13, 2013 Experiment 1: Determination of Density Introduction The purpose of this experiment was to be able to measure the density of water and an unknown substance with a buret and an analytical balance. The inhibited water-based systems cannot totally prevent water wetting of the rock pores, but they can minimize it.

This means that Bentonite cannot do well when used with Salty Water. Bentonitic muds form filter cakes with a honeycomb structure. Barite on the other hand has a high clay yield and it does not exhibit any signs that are significant to swelling. Density, Laboratory glassware, Liquid 923 Words 4 Pages Drilling Mud density or specific gravity is the most significant measurement required and no reliable visual estimate exists. Also, cuttings erosion usually is accompanied by wellbore erosion, which leads to hole washout.

Originally thought to occur under static conditions, barite sag is recognized now to occur more readily under dynamic, low-shear-rate conditions. Many researchers highlighted that physical, mechanical and rock mass properties of a rock should firstly to be determined while finding out rock's drillability and cuttability. The lever arm is calibrated, the rider also acts as a counterweight and there is a level glass to determine when the instrument is balanced. Tabulate the results in an appropriate table. Clay, Continuum mechanics, Fluid 3677 Words 15 Pages cenresinpub. The efficacy of using traditional rheological measurements as indicators of barite sag potential are addressed.

Derivation of mudcake parameters is illustrated and comparison between simulated and measured filtration sequences is presented. The cup is attached to one end and the counter weight on the other end. The density can be calculated by dividing the mass per volume. Due to this fact we have standards of measurement. After the mixture we must weight 25. After obtaining the pure compound, a melting point determination procedure can be done using a mel-temp device to correctly identify the compound if its identity is unknown.

Approximation error, Density, Length 785 Words 3 Pages Eric Wu 117 Experiment 1. Machines of this kind build up a pressure which, on being released, drives the piston forward Fig. Once all the needed chemicals were added we waited for about 70-75mintues for the reaction to take place. Flow loop test results indicate that pipe rotation has a greater impact on reducing sag when the pipe is eccentric rather than concentric. Drill string, Drilling fluid, Drilling rig 832 Words 6 Pages of the Experiment: determination of densities Introduction The density of a sample of matter represents the mass contained within a unit volume of space in the sample. Theory: Drilling fluids are used during the drilling of boreholes, either for oil wells or water boles holes. The bioremediation technology used in this case was based on the use of naturally occurring microorganisms, isolated from the contaminated site, which were capable of using the contaminating substances as nutrients.

Based upon experimental results, field technology has been developed to predict the potential for barite sag of invert-emulsion muds and to provide remedial measures through ultra-low shear rate viscosity modification. When drilling, the drilling fluid is circulated continuously so that it can provide hydrostatic pressure in the drilling hole column so as to control the pressure exerted by the oil bearing formations. Oil-based muds Oil-based muds were developed to prevent water from entering the pore spaces and causing formation damage. Return permeability When drilling reaches a hydrocarbon-bearing zone, of great concern is the potential to damage the formation and thereby to reduce the ability of the well to produce hydrocarbons. Calcium carbonate, Chloride, Chlorides 6029 Words 20 Pages particles in the compound are excluded from the crystal lattice. Error, Measurement, Measuring instrument 1872 Words 6 Pages. The Marsh Funnel measures the apparent viscosity.
