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

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
