    CHAPTER 1: BACKGROUND 1.1 ENHANCED OIL RECOVERY Oil production is differentiated into three stages: primary, secondary and tertiary, which is also known as Enhanced Oil Recovery (EOR). Primary oil recovery is restricted to hydrocarbons that naturally produced to the surface, or those that utilization artificial lifts, for example, pump jacks. The secondary recovery utilizes water and gas injection, dislodging the oil and driving it to the surface. US Department of Energy stated that by using…

    The purpose of this research paper was to determine the influence of cellulose and date palm pad on cooling efficiency, low cost, and reduced temperatures. A study was undertaken to compare the two types of pads to determine the cooling efficiency, low cost, and reduced temperatures. The study found that cellulose pads gave high cooling efficiency, but at the same time increased the total cost. Date palm pads saved water compared to cellulose pads. The cost of using the date palm pad was less…

    • 6 Pages

    Friction loss is defined as the pressure loss or head loss that usually occurs in pipeline fluid flow because of the viscosity effect near the surface of the pipe. When the fluid flows along the pipeline, it produces frictional resistance thus results in loss of energy or total head loss of the fluid. Therefore, experiment was conducted to verify the Darcy Weisbach equation by determining the pressure loss along a horizontal pipe. Figure A below shows the diagram of friction loss along a…

    The Freezing point of water is 32° fahrenheit, But does anything affect the freezing point of water? The effect of salt and sugar lowering water’s freezing point is called Freezing Point Depression(FPD). When water freezes, its molecules slow down and “stick” together, and eventually slow down so much they stay in place and become a solid. However when salt or sugar is added, it “interferes with the formation of the crystalline bonds between water molecules that give ice its solidity”, Written…

    For the controlled dH2O, it was hypothesized that no disks would float. The reason is because there is not enough CO2 for sample organism to absorb to allow it to do so. Looking at Figure 5.1, the slope of the line is y=0. This supports the hypothesis because there are no floating disks. For the 0.2% bicarbonate solution, it was hypothesized that if the leaf disks in this solution were placed under a lamp, then the disks would float. Figure 5.1 supports this claim, as there is an almost linear…

    To begin changing the oil on a 1994 Formula Firebird, the vehicle must be parked on a flat surface and turned off. The motor will need time to cool, so as not to burn whoever is performing the oil change. During the time period in which the engine is cooling down, place a three-ton capacity jack under the car and position it below the frame behind the front wheel on the driver's side of the car. Then, push down on the lever of the jack until the car has been raised enough for a person to crawl…
