Fundamentals of Reservoir Engineering

Introduction

This Fundamentals of Reservoir Engineering training course introduces reservoir engineering concepts and methods to enable cross-disciplinary exchange of ideas and experience. It provides the required input to help you understand questions crucial to the reservoir engineer: How much oil & gas is there (accumulation)? How much can be recovered (reserves)? How fast can it be recovered (rate)? By the end of this training course, participants will have gained a foundational understanding of reservoir engineering that they can use while moving forward in their training.

This GLOMACS training course will feature:

• Discussions on the role of reservoir engineering in exploration and production as well as how reservoir engineers interact with other disciplines in the Petroleum Industry
• A description of Reservoir rock properties, Darcy’s Law and Fundamentals of fluid flow in a porous media
• A description of Reservoir fluid phase behaviour and reservoir fluid properties
• An Overview of well testing and application of the diffusivity equation
• An outline of different drive mechanisms and discussion of the recovery factors
• Principles of Material Balance and Decline Curve Analysis
• Use of fractional flow equations and Immiscible displacement concepts
• Definition of reserves, estimation of oil and gas in place and Production Forecasts

Objectives

By the end of this training course, participants will:

• Describe a hydrocarbon reservoir and list the fluids found in it
• Illustrate with diagrams how these fluids are distributed in a hydrocarbon reservoir
• Describe and explain porosity, permeability and fluid saturations
• Determine the properties of natural gas, oil and water
• Explain and define saturated reservoirs, undersaturated reservoirs, bubble point pressure, oil and gas formation volume factors, gas oil ratio
• Calculate the volume of hydrocarbon in place and recovery factors Derive the general material balance equation, modify it and use it to calculate hydrocarbon in place for gas reservoirs, saturated reservoirs and under saturated reservoirs
• Use the Havlena and Odeh technique to determine oil in place for saturated reservoirs and under saturated reservoirs
• Use of well testing data in determining average reservoir pressure, productivity index, permeability, and skin effect
• Discuss the recovery factors of different drive mechanisms
• Explain the use of fractional flow equations and Immiscible displacement concepts
• Perform decline curve analysis

Training Methodology

This Fundamentals of Reservoir Engineering training course will utilise a variety of learning techniques to ensure maximum understanding, comprehension and retention of the information presented. The daily workshops will be highly interactive and participative. This involves regular discussion of applications as well as review questions on each topic.
