Reservoir engineering and simulation

Synthesis

Day 1 :1) Introduction
Modelling in the workflow of a reservoir study
2) What is reservoir modelling ?
– Basic equations
– Principle of simulation
– Discretization in space , in time
– Types of simulators
– Solution of non linear equations

Day 2 :
3) Dynamic synthesis
Understanding the field behavior by the 3 geosciences disciplines
4) Building the model
Reservoir geometry and main features
Gridding
Model input : petrophysics, fluids
Upscaling
HC accumulation – Uncertainties

Day 3 :
5) The limit conditions
Field segmentation
Modelling the aquifer
The well
Inflow – Outflow – The well in the model
6) Model initialization
Pressure
Saturation
Model stability

Day 4 :
7) Quality control
Petrophysics and HC in place
QC of well data
CPU optimization
Common pitfalls and recommendations
8) History Matching (HM)
Methodology
Data to match, control parameters
Workflow – best practice
Post processing and result analysis

Day 5 :
9) The forecast
Methodology
Simulation data and control (forecast vs HM)
Simulation under constraints ( surface, drilling)
