Event Details

 Course overview

This is a basic reservoir simulation course that is designed for novice engineers in reservoir simulation of engineers needing a refresher in the basics of reservoir simulation. Th course begins with discussion of the fundamentals of reservoir simulation. Why and how  and under what conditions reservoir simulation is necessary over, for instance, a simple material balance. The course refreshes the student in the basics of the partial differential equation, the diffusivity equation, beginning in 1-D coordinate systems. The analytical solutions to the diffusivity equation are discussed and the assumptions are presented that allow the use of finite differences to be utilized to create a system a algebraic equations that can be solved by iterative procedures. We then discuss the solution methods, implicit, explicit and IMPES methods. We discuss the conditions for stability and convergence and the applicability of each of the methods. We review matrix solvers and establish the fundamental engine in all finite difference simulators.

After this we discuss simple 1-D, single phase applications for simple short term well tests. We cover the basics of time step optimization and move on the more sophisticated problems like design of a hydraulic fracture, design and simulation of horizontal wells, and eventually multi-well simulation of pattern water injection models that require understanding the basics of two phase flow, gridding a pattern area, optimizing specific patterns based on reservoir properties and analysis of saturation fronts as water injection proceeds. We conclude with the concepts of history matching with field case histories and demonstration of full field modelling. During the course we have modules that allow the attended to perform practical  simulation with the use of RFD’s TNavigator.

The course is designed for

This course is designed for engineers with a good grasp of fundamental reservoir engineering principles. This could be a fresh graduate with limited exposure to simulation principles and applications or more experienced engineers that have had limited exposure to numerical simulation and would like to learn or refresh their knowledge base. The course is designed such that attendees with little or no experience in reservoir simulation can pick up the principles and run a modern reservoir simulator for very simple to more complex small models (i.e. single well to multi-well pattern models)

Course objectives

Learn or refresh the basic mathematics behind numerical simulation
Discuss the practical use of reservoir simulation
Learn the numerical methods to convert partial differential equations into simulation equations using finite differences
Teach the attendee how to simulate simple single well models like well tests, hydraulic fracturing and horizontal wells with practical modules and direct use of software
Discuss the concepts of a successful history match in preparation for forecasting infill wells, water injection projects and gas injection EOR
Fortify the learnings with case history studies of simulation projects
Demonstrate large projects with multi-million cell models and the current state of the art in speed efficiency for TNavigator
