Oil and Gas | Reservoir Engineering
Business Impact: Participants will develop the skills to add value by accurately assessing recoverable volumes, enhancing hydrocarbon recovery, and developing more robust reservoir simulation models.
This course aims to provide the practicing reservoir engineer with a range of analysis techniques and tools relevant to contemporary field development trends. Fundamental concepts will be discussed to ensure a solid foundation for understanding the applicability and limitations of the techniques presented. The learning will be supported and reinforced by examples and exercises throughout the course.
Duration and Training Method
A virtual classroom course divided into 10 three-hour webinar sessions over a two-week period (equivalent to a five-day classroom course), comprising lectures, discussion, case studies, and practical exercises to be completed by participants during and between sessions. Problems will focus on understanding the concepts and may require the use of a scientific calculator or laptop computer, but no specialized engineering software applications will be used.
Participants will learn to:
- Develop a robust understanding of the key concepts underpinning the practice of reservoir engineering; encompassing rock and fluid properties, and the physics of multiphase flow in porous media.
- Implement a range of analysis techniques to quantify recoverable volumes and productivity of oil, gas, and gas-condensate wells and reservoirs.
- Expand traditional techniques to provide familiarity and understanding of more contemporary reservoir analysis for improved and enhanced recovery techniques, and resource-play reservoirs.
- Determine the parameters for resource classification.
- Assess and apply techniques to assess Reserves volumes.
- Illustrate the appropriate uses of reservoir simulation and provide practical guidelines for planning reservoir modelling studies.

- 'Resource plays' (shale gas, tight oil and gas, analysis and performance prediction techniques)
- Improved/Enhanced Oil Recovery (IOR/EOR)
- IOR categories (infill recovery, miscible gas injection, chemical floods, thermal techniques)
- Screening and analysis of alternative techniques
- Reservoir simulation
- Principles of simualtion (finite-difference, streamline, alternative simulator types, input data, well models, history matching)

Who Should Attend and Prerequisites
The course is designed to provide practicing mid- to senior-level engineers with a fuller understanding of the basis and applicability of their engineering work and to introduce additional approaches to their reservoir analyses. Manages and team leaders could also benefit from exposure to applied reservoir engineering topics.
