Advanced Training Workshop for Upstream Oil & Gas Professionals
3 days of interactive sessions - a must for all personnel involved in the upstream oil/gas industry including engineers, geologists, economists and
planners who work with fiscal systems. This is a practical hands-on workshop on understanding the role of petroleum economics in
upstream petroleum industry investment decision-making.
An intensive workshop giving a complete and in-depth understanding of the use of the techniques of upstream petroleum economic analysis and risk analysis as currently practiced. Workshop participants can expect to receive a thorough understanding of the context of such analyses as well as practical instruction and an appreciation of the analytical techniques used.

Workshop Overview

This 3-day Upstream Petroleum Economics is specially designed to equip delegates with the skills and understanding to evaluate and make decisions on upstream petroleum projects. The workshop covers cash flow analysis, economic indicators, risk analysis and fiscal analysis. Throughout the workshop, participants will complete practical exercises to reinforce their understanding of the concepts. In today’s volatile oil price environment, the analysis of risk in an economic evaluation of an upstream oil and gas investment is absolutely crucial. This course will give a complete understanding of the techniques of economic analysis and risk analysis as currently practiced in the oil & gas industry. Course participants will receive a thorough understanding of the context of economic analysis as well as practical instruction and an appreciation of the analytical techniques used.

The workshop will rely heavily on the participants carrying out worked examples and examining cases to aid their understanding of the concepts introduced.

Workshop participation and hands-on exercises will enable you to -
  • UNDERSTAND the way in which the oil and gas industry evaluates and makes decisions on petroleum project investments through a hands-on learning.
  • APPLY risk analysis to oil and gas investments.
  • EVALUATE petroleum fiscal and PSC terms of worldwide.
  • PREPARE oil and gas industry economic analyses and to review critically the analyses prepared by others.
  • DISTINGUISH between good and bad practice in oil and gas industry economic/financial evaluation.
The workshop provides participants with critical information necessary to create the right commercial framework.(Participants should bring laptops to work on)

This critical 3 day workshop will be of most benefit to:

Geologists, Explorationists, Accountants, Economists, Engineers, Financial managers, Negotiators, Geophysicists, Managers and staff from service industries, Bankers, Brokers, Consultants, Corporate Planners, Policy Analsysts, Legal Advisers, In-House Counsel, Commercial Managers, Senior Petroleum Engineers and Government Representatives for National Oil Companies
