CHAPTER 2 RECOVERY EFFICIENCY OF AN EOR METHOD 2.1 SWEEP EFFICIENCY The overall recovery factor (efficiency) RF of any secondary or tertiary oil recovery method is the product of a combination of three individual efficiency factors as given by the following generalized expression: Fluid properties influence all three components of recovery efficiency. 1. Viscosities are found in the definition of mobility ratio‚ which affects areal and vertical sweep efficiency‚ including viscous fingering. 2

Introduction We are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid. I will add calcium carbonate (marble chips) to hydrochloric acid. When calcium carbonate is added to hydrochloric acid a reaction takes place. The solution fizzes and gives off the gas carbon dioxide. I will collect this gas in a gas syringe and will time how long it takes for the reaction to produce 100cm3 of carbon dioxide. CaCO3 +2HCL Co2 +CaCl2 +H2O CalciumHydrochloricCarbonCalciumWater

IEOR E4707: Financial Engineering: Continuous-Time Models c 2009 by Martin Haugh Fall 2009 Black-Scholes and the Volatility Surface When we studied discrete-time models we used martingale pricing to derive the Black-Scholes formula for European options. It was clear‚ however‚ that we could also have used a replicating strategy argument to derive the formula. In this part of the course‚ we will use the replicating strategy argument in continuous time to derive the Black-Scholes partial

as other physical phenomenon. Our initial hypothesis about this phenomenon was that water stream breaks when its flow turns from laminar state to turbulent state. Then we extended this study including the influence of surface tension in this phenomenon. We expected that as surface tension decreases‚ the stream will break with higher velocities then before. Ⅰ. Introduction We often see in science museums‚ using a strobe‚ how a water stream breaks and forms drops while performing a parabolic

CHAPTER I THE PROBLEM AND ITS SETTING This chapter provides the background‚ objectives and significance of the study‚ and the scope and delimitations that will give some information about our study “Prolonging the Tenacity of Bubbles”. INTRODUCTION Bubbles can be seen everywhere. They are used in kids’ parties and other outdoor activities like picnic. They are also cheap and easy to make. You just need dishwashing liquid‚ glycerin and water. The purpose of this experiment is to

ACTIVITY: THE CAT’S MEOW / MILK CO-MOTION PURPOSE: To observe the interaction of detergent with the fat of the milk and food color 1. Provide a possible explanation of phenomenon you observed based on the result of your experiment. When food color is added to milk‚ it floats because it is less dense than milk. The non-polar fat in the milk prevents the food color from spreading‚ as it cannot participate in hydrogen bonding with water. When detergent is added to milk and the food color‚ the
