Summary

Business Impact: By building a greater awareness of reservoir engineering principles, participants will be able to communicate more effectively with their Reservoir Engineering colleagues, ensuring better integration between disciplines, thereby improving the efficiency, effectiveness, and quality of business activities.

This course examines the standard reservoir engineering processes and techniques, particularly their interface with geoscience activities. This course illustrates, with examples, the use of subsurface data in the construction of a reservoir model. It covers three related main themes: static reservoir models; developing dynamic reservoir simulation models; and reservoir management during the producing life of a field. This course covers the fundamentals of fluid flow in porous media, from a rock and fluid perspective.

Duration and Training Method

This is a classroom or virtual classroom course comprising a mixture of lectures, discussion, case studies, and practical exercises.

Course Overview

Participants will learn how to:

  1. Operate more effectively, and work more collaboratively, with their Reservoir Engineering colleagues.
  2. Interpret original fluid contacts, through analysis of logs and pressure vs. depth profiles, prior to production start-up; understand saturation vs height relationships and estimate original hydrocarbon in place volumes, for both oil and gas reservoirs.
  3. Employ fluid sampling techniques. Differentiate the physical and chemical properties of hydrocarbons and their description through phase diagrams.
  4. Examine the uses and importance of well tests and appraise how analysis is conducted. 
  5. Examine the controls on fluid flow in the reservoir, the balance of viscous, capillary and gravity forces and the impact of reservoir drive mechanisms including depletion, water and gas drive.
  6. Analyse production performance in the wellbore and debate artificial lift techniques. Compare production enhancement through stimulation, horizontal wells, and completion techniques. 
  7. Examine the processes and interfaces of building both static and dynamic reservoir models. Show awareness of the principles, objectives, demands, and uses of reservoir numerical simulation techniques and its validation.
  8. Analyse the importance of continued reservoir management for forecasting future production profiles and maximising economic hydrocarbon recovery from a producing field over the complete life cycle.
  9. Compare the Enhanced Recovery techniques: steam and fire flooding; miscible and immiscible gas displacement.

The material covered in this course is built around the reservoir model, which can be constructed using analytical (calculator) or numerical (simulation) processes. The process is in three parts:

  1. Building a static reservoir model
  2. Developing a dynamic model
  3. Reservoir management during the producing life of a field

The following topics will be covered:
