N448 Practical Reservoir Performance Analysis
N448 Practical Reservoir Performance Analysis
This course describes the tools used by Petroleum Engineers to analyse and predict the performance of hydrocarbon reservoirs. It covers methods for interpreting well and reservoir performance; estimating recovery factors from primary, secondary and tertiary recovery processes; predicting flowrates from oil and gas wells; assessing the performance of both fractured and non-fractured reservoirs.
This is a 5-day course consisting mainly of lectures, supplemented by integrated class exercises which apply the techniques described to typical subsurface data-sets in order to solve petroleum engineering problems of practical interest. Two data-sets are used: one for a field in the pre-development phase and another for a field already in production.
Participants will learn to:
The course is structured as follows:
Day 1 (introduction)
-Decline curve analysis
Day 2 (well performance)
-An introduction to the radial flow equation
-Practical solutions to the radial flow equation (PI, well testing, aquifers)
-Inflow performance (oil & gas)
-Outflow performance (including stimulation & artificial lift)
-Well testing and well test analysis
Day 3 (primary drive reservoirs)
-Phase behaviour recap
-The Black oil model
-Sampling & lab experiments
-Other sources of PVT data (simple flash calculations, compositional modelling, correlations)
-Material balance (incl. prediction of RFs)
Day 4 (secondary and tertiary drive reservoirs)
-Relative permeability & capillary pressure recap
-Vertical sweep efficiency (the fractional flow equation)
-Areal sweep efficiency (streamlines)
-Relative permeability curves for real reservoirs (pseudo curves)
-Introduction to EOR techniques
Day 5 (production forecasting)
The q vs Q curve
Production profiles based on exponential decline
Introduction to tank models
Introduction to reservoir simulation
The course is ideal for geoscientists and other non-petroleum engineers seeking a more detailed knowledge of Reservoir and Petroleum Engineering and its application to real-life problems. The course is also for suitable for Reservoir and Petroleum engineers who require a refresher in this area.
Participants should be comfortable with the use of Excel and should have a basic understanding of Petroleum Engineering. A pre-read document will be provided that summarises the basic knowledge assumed by this course.

Alun Griffiths graduated from Imperial College, London in 1982 with a First Class Honours degree in Chemical Engineering. He joined Shell International Petroleum Maatschapij after graduating and spent four months on a training assignment in The Netherlands before being transferred to Thailand. Alun spent nearly 4 years in Thailand, working on the wellsite for 18 months and then in the office as an operations engineer. He was posted back to the UK in 1986 and joined the Brent Field Business Unit, where he worked in a variety of reservoir engineering positions. In 1990, Alun left Shell and joined Intera-ECL as a reservoir engineering consultant, where he remained until 1998. During his time at Intera-ECL, Alun worked on a wide range of reservoir engineering projects across the globe, with particular emphasis on reservoir simulation, field evaluation and development planning. He also presented a number of ECLIPSE simulation courses and managed a large field rehabilitation feasibility study, sponsored by the World Bank, of the Kala-Buzovni Mashtagi and Bibi Eybat fields in Azerbaijan; the Bibi Eybat field is one of the oldest producing fields in the world, having been in production since the 1870’s.
In 1998, Alun became a freelance reservoir engineer, through his own consulting company Griffin Petroleum Consulting Ltd. He has worked for large and small companies, on a wide variety of international reservoir engineering projects, ranging from the simulation of small gas discoveries to the evaluation of large, mature oil fields. He has taught a postgraduate module on Petroleum Technology to M.Sc. Petroleum Geosciences course, now at Manchester University, since 2003 and has also given a number of in-house courses to various clients on reservoir modeling, reservoir engineering and ECLIPSE.
