About this Training Course
A decision to drill an exploration well with the objective to find a new oil or gas field must be based on sound assessment of the prospect risk and of the volumes. What is the chance that a well will find hydrocarbons, and how much could it be? Risk and volume assessments form the basis for decisions to drill a well or not, and as such form the link between subsurface evaluation and the business aspects of the petroleum industry. This course explains how risks and volumes can be assessed in a realistic manner, based on a sound understanding of the geological details of the prospect as well as its regional geological setting and current play understanding.
The course will demonstrate that realistic risk and volume assessment is not a “black box” operation, but requires geological understanding of the prospect, and the regional setting.
By the end of this course, participants will be able to understand:
- The fundamentals of risk and volumes assessment; translating geological understanding into reasonable numbers and ranges.
- The difference between risk and uncertainty.
- Fundamentals of statistics; including explanation of distribution curves, understanding of expectation curves, do’s and don’ts for adding risked volumes, and Bayes theorem.
- Uncertainty of trap, reservoir, seal and charge, illustrated by examples.
- Guidelines and exercises for estimating risks realistically and consistently.
- Calculating volume ranges for prospects and for portfolios of prospects; how to add prospect volumes for a correct representation of prospect portfolios.
- Incorporation of geophysical evidence (DHIs) in a realistic risk assessment.
This course has been designed in the first place for geoscientists working in exploration, for prospect portfolio analysts and for their direct supervisors. It will also benefit staff from disciplines working closely with exploration staff, such as reservoir engineers, petrophysicists and geophysicists.
Each topic is introduced by a lecture, and learning is re-enforced by practical exercises and discussions. Hand-out materials in electronic format will be provided.
Dr. Jan de Jager has a PhD in Geology from the University of Utrecht. He joined Shell in 1979 as an exploration geologist, and worked in several locations around the world such as Netherlands, Gabon, USA, Australia, Argentina, and Malaysia in technical and management positions. During the last 10 years of his career, he was responsible for the quality assurance of Shell’s exploration prospects in many parts of the world and for upgrading and replenishing Shell’s global exploration portfolio. During this period, he had also developed extensive expertise in Prospect Risk and Volume assessments for which he ran successful internal training programmes. Following his retirement from Shell in 2010, Dr Jan de Jager took on a position as part-time professor at the University of Amsterdam and also serves as a consultant exploration advisor for various E&P companies.
