Petroleum Economics and Fiscal Modeling

Understand how oil and gas companies value upstream assets – exploration acreage, undeveloped discoveries, producing fields – and make decisions whether to invest or not.

This highly practical and experiential three-day programme will empower you to:

  • Understand how key project assumptions – production, prices and costs – are modeled in the oil and gas industry
  • Learn what various economic indicators – like NPV, EMV and IRR - actually mean
  • Examine how assets at different stages of their life are valued in investment decisions, including the application of risk analysis to exploration opportunities
  • Review the vast array of fiscal and contract terms employed by governments around the world for oil and gas projects and identify trends in the evolution of fiscal terms
  • Work with the spreadsheet models to understand how different fiscal terms are included in the cash flow analysis and evaluate the impact of the terms on project economics
  • Compare the pros and cons of different fiscal terms from both investor and government perspectives
  • Participate in a negotiation of fiscal terms, based on the knowledge learned, and supported by the spreadsheet models developed, on the course.
  • Explore how the various fiscal systems applied around the world impact upon these values and decisions.


What is the programme about?

Develop your knowledge to understand how oil and gas companies measure the economic value of assets and the impact of fiscal terms on those values. Gain ‘hands on’ experience of combining key project assumptions and fiscal terms in spreadsheet models, to generate values for different assets. Consider how government and investors will consider the same fiscal terms very differently – and negotiate a fiscal deal!

Our expert trainer draws on his extensive knowledge gained from over 25 years of modelling, analyzing, negotiating and advising on fiscal terms to advance your practical knowledge and skills.
