Modern reservoir modelling adopts 3D computer techniques often used to construct large and complex models. This modular workshop, set at basic or cross-over level, focuses on principles which the geologist should not lose sight of, regardless of computing power available. It demonstrates the principles of effective field evaluation for development studies, ranging from appraisal to engineered recovery operations. It focuses on the controls that geological heterogeneities exert on subsurface fluid flow, and shows how an understanding of reservoir characteristics will improve the reliability of geological and reservoir engineering models.
Course Level: Basic Instructor: John H. Martin
Designed for you, if you are...
A reservoir or petroleum engineer, who wishes to learn how geological insight can improve understanding of the reservoir
A geologist or geophysicist new to production geoscience work, who wants a greater insight into the work of the reservoir engineer and how to tailor the results of geological studies into a format most useful to the requirements of field development planning
How we build your confidence
The specific workshop modules and sections included will be varied to suit your needs, your background and the reservoir types you are most commonly working with.
Exercises and demonstrations form important parts of the workshop modules; including: - Scales of investigation of logs, cores and well tests in relation to reservoir heterogeneities - Well correlation and mapping techniques - Plotting and averaging methods for permeability data, prediction of permeability - Use of pressure data in determining fluid contacts and reservoir compartmentation - Capillary pressures and the concept of Free Water Level - Design of simulation model input from geological data
If there is access to client’s own core material for part of the workshop, relevant practical sessions can be run ‘hands-on’.
The workshop is accompanied by a manual in ‘book’ form, with extensive references for further reading.
