| Outline and Purpose of the Course |
Development of mineral resources and energy resources is essential to the sustainable development of our society. In this class, the exploration and development process of natural resources are reviewed including the environmental conservation and harmony. First, fundamentals of reservoir engineering for oil and natural gas are lectured. Second, methods and techniques used to reduce environmental loads in modern resources development are reviewed and their theoretical backgrounds are lectured. Fundamentals of geochemical modeling, that is applicable to simulate hydrogeochemical processes in mine drainage treatment, is also introduced. |

| Course Goals |
The goal of this class is to understand the natural resources development concerning environment and master the reservoir engineering needed for the exploration and development of oil and natural gas resources. In addition, followings are also a goal of this class. Students understand flow of resources development, and methods and techniques that are used to reduce environmental loads therein. Students understand and come to be able to explain theoretical backgrounds of the techniques that are utilized to reduce environmental loads in resources development. Students can conduct basic geochemical modeling. |

| Schedule and Contents |
1st: From exploration to development & production for mineral and energy resources The engineering flow from exploration to development & production of mineral and energy resources indispensable for the sustainable development of human society is lectured. Environmental conservation and environmental harmony in resources development are also included. 2nd: Basic concept of reservoir engineering The basic concepts of reservoir engineering, such as the basic properties of reservoir rock and reservoir fluids, reservoir pressure, and oil and gas recovery, are explained. 3rd: Basic equation of radial flow (Part 1) The basic equation of the radial flow of a reservoir fluid to a well is derived, and Inflow equations for the semi-steady state and steady-state conditions are described. 4th: Basic equations of radial flow (Part 2) Constant Terminal Rate Solution, which is the solution of the basic equation of radial flow of oil to a well when the oil is produced at a constant production rate and gives the change of bottom hole pressure with time, is derived. 5th: Oil well testing (Part 1) The basic concept of oil well testing and analysis methods for the pressure drawdown and buildup tests are explained. In addition, the theory of Matthew, Brons, and Hazebroke is explained, and then the evaluation methods of average reservoir pressure (MBH method and Dietz method) are explained. 6th: Oil well testing (Part 2) The analysis method for the multi-rate pressure drawdown test is explained. The effects of partial completion and after-flow are also explained. 7th: Gas well testing (Part 1) The basic concept of gas well testing and the equations used for the analysis are explained. 8th: Gas well testing (Part 2) The analysis methods for the gas well testing are explained. 9th: Basic theory of immiscible displacement in the reservoir (Part 1) Fractional flow theory and Buckley-Leverett equation for the one-dimensional displacement of oil by water are explained, and Welge's method for evaluating oil recovery is explained. 10th: Basic theory of immiscible displacement in the reservoir (Part 2) The oil displacement by water under the conditions of segregated flow and allowance for the effect of a finite capillary transition zone is explained. The method to evaluate oil recovery under these conditions is also explained based on the fractional flow theory. 11th: Basic theory of immiscible displacement in the reservoir (Part 3) The oil displacement by water under the stratified reservoir condition is explained. The method to evaluate oil recovery under this condition is also explained based on the fractional flow theory. 12th: Enhanced oil recovery Various enhanced oil recovery methods such as chemical, miscible gas, and thermal flooding are explained. 13th: Resources development and environmental loads Flow of resources development and their impacts on surrounding environments are reviewed, referring to actual examples of mine pollution. Methods and techniques that are used to reduce environmental loads are introduced. 14th: Theoretical backgrounds of the techniques to reduce environmental loads Fundamental theories and principles relevant to treatment of hazardous substances (e.g., mine drainage) generated through resources development are lectured. 15th: Fundamentals of geochemical modeling Basics of geochemical modeling are lectured. Practical training, in which treatment of mine drainage is assumed, is conducted using representative geochemical modeling code, phreeqc. |
