Basic Reservoir Engineering - BR - eLearning Course

Program Overview

Delivered virtually with a blend of self-paced learning, instructor-led sessions, and interactive exercises, this program is ideal for professionals seeking to enhance their knowledge in reservoir engineering.

Program Outline

Degree Overview:

This workshop is delivered virtually through PetroAcademy, integrating multiple learning activities like self-paced e-Learning, virtual instructor-led sessions, discussion forums, group exercises, case studies, quizzes, field trips, and experiential activities. The Basic Reservoir Engineering Blended Program is designed to help participants develop a more complete understanding of the characteristics of oil and gas reservoirs, from fluid and rock characteristics through reservoir definition, delineation, classification, development, and production. Data collection, integration, and application directed toward maximizing recovery and Net Present Value are stressed.

Course Content:

• This is Reservoir Engineering: About the Principal Tasks of a Reservoir Engineer, About the Principal Tools of a Reservoir Engineer, How this course is organized to cover these topics.
• Reservoir Rock Properties: Different types of rocks, Primary rock properties from a reservoir engineering point of view, How rock properties are measured, How rock property values are interpolated/extrapolated throughout the reservoir.
• Reservoir Fluid: Describe how fluids change in response to changes in pressure and temperature, Define the engineering properties of reservoir fluids, Describe the make-up of reservoir fluids, Describe how fluids are sampled, Describe how fluid properties are measured in the laboratory.
• Reservoir Flow Properties: Explain the origin of Darcy's law and how it evolved, State the difference between gravity and the pressure gradients, and how they play a role in determining the rate of which fluid could flow in the porous medium, Identify the differences between the equations of Linear versus radial flow when calculating the flow, Explain how do heterogeneities affect the flow in porous medium, and how Darcy's law can be applied to homogenize to calculate effective permeability, Differentiate between oil and gas flow, Apply Darcy's law to gas and oil, Calculate the amount of fluid that is flowing when you have single cell phase vs single phase oil, Describe the Importance of non-Darcy effect on well performance, Apply Darcy's law when calculating the rate of the of oil and gas well, Identify the differences between layers in parallel and layers in series, Discuss the effective permeability of both layers in parallel and layers in series, State limitations of Darcy's law, Assess the differences between gas and oil reservoirs, Describe the effect of non-Darcy flow.
• Reservoir Material Balance: Describe the purpose of the material balance technique to estimate the initial hydrocarbons in place, Differentiate between volumetric analysis and material balance technique, State the basic principle of material balance analysis, Describe the principles behind material balance equation, Identify the data that is needed to apply the material balance equation and the uncertainties associated with collecting such data, Identify the purpose of the modified black oil model in material balance equation, State the assumptions involved in applying the material balance equation, Identify the limitations of material balance technique, Develop the material balance equations from the first principle, Identify and explain the different mechanisms influencing the production of hydrocarbons and how they are incorporated in the material balance equation, Understand the necessary equations to be used depending on the type of reservoir from which hydrocarbons produce, Develop appropriate equations for dry gas, wet gas, condensate, volatile oil and black oil reservoirs, Describe modifications of material balance equations to estimate the initial oil and gas in place, Explain the Havlena and Odeh method and the appropriate way to linearize the material balance equations, Express the importance of water influx and how to detect the presence of aquifer based on production data, Recognize the uncertainties associated with predicting the water influx as a function of time.
• Decline Curve Analysis and Empirical Approaches: Perform Basic Statistics, Calculate Decline Curve Analysis, Estimate Recovery Factors.
• Pressure Transient Analysis: Pressure transient analysis concepts, terminology, equations and objectives, Pressure transient analysis in buildup and drawdown tests, Time period analysis - challenges and objectives, Semi-log and log-log analysis.
• Rate Transient Analysis: Describe the relationship between 'rate transient analysis' and 'pressure transient analysis', Describe the situations under which rate transient analysis would be preferred to pressure transient analysis.
• Reservoir Fluid Displacement: Fluid displacement as immiscible, linear, and vertical (overcoming gravity), Dispersed and segregated flow, Aquifers models, Coning in oil/water systems, including when it is most likely to occur, and how to prevent it.
• Enhanced Oil Recovery: Discusses the modification of rock and fluid properties in tertiary recovery, Describes (at a high level) the range of secondary and tertiary recovery techniques currently available (and relates them back to rock & fluid properties).
• Reservoir Management: Retain flexibility in reservoir management without giving up key principles for depletion, Build flow units critical to reservoir management of an asset, Describe how the value of an asset is defined, Explain the roles of risk and uncertainty in that valuation, Evaluate vertical equilibrium and no-crossflow, and how to get the most out of each through integrated technologies from multiple disciplines.
