Business Impact: This course will provide attendees with methods to identify and incorporate subsurface, facilities, and commercial uncertainties into an economic evaluation of a project.  Additionally, it will provide practice with tools to manage the associated risks, thereby reducing the investor’s exposure to financial downside while taking advantage of potential upside.

This course details the main financial concepts and economic evaluation techniques and related financial concepts that are used in the oil and gas upstream business to assist decision making. The course will focus on the conversion of hydrocarbon volumes to ‘monetary value’ and the requirement for consistent means of determining the attractiveness of investment opportunities through the field lifecycle. Portfolio decision making will also be discussed.


"I thought this course was great. It delivered on all the defined objectives. The activities were helpful and resembled actual scenarios that might be encountered on the job."

Duration and Training Method

This is a classroom or virtual classroom course comprising a mixture of lectures, discussion, case studies, and practical exercises involving the use of bespoke software tools.

Course Overview

Participants will learn how to:

  1. Employ the principal elements and techniques of petroleum economics.
  2. Analyse wider trends that determine worldwide hydrocarbon reserves, supply and demand pressures, and forecast trends for the future.
  3. Illustrate how petroleum economics is critical to the project decision-making process.
  4. Analyse the nature of discounted cash flow, Net Present Value, Rate of Return indicators, and the Cost of Capital.
  5. Demonstrate how Profitability and Efficiency are measured for a project, including the role of inflation.
  6. Distinguish the various Petroleum Fiscal Systems in operation around the world (tax and royalty-based, PSC’s).
  7. Examine more fully how projects are screened and ranked economically.
  8. Perform sensitivity analysis, Monte Carlo simulation, and decision tree analysis.
  9. Apply quantitative risk analysis tools, such as the Bow Tie model, to identify and manage project risk and to capture actions on a risk register.
  10. Understand the risk management benefits of building a portfolio of E&P assets.

  • Development concept selection and the concept select matrix

Portfolio Management

  • Portfolio theory
  • Portfolio benefits in an E&P context

E&P professionals of all disciplines (including geoscientists, engineers, and managers) who wish to obtain an understanding of petroleum economics and risk analysis, and those who are transferring from a technical discipline into the world of commercial evaluation.

Mark Cook is a Principal Reservoir Engineer for TRACS International. His specialties are reservoir engineering, petroleum economics, and risk analysis and field development planning, subjects in which he has developed and delivers training courses to advanced levels.

Mark graduated with a degree in Chemical Engineering and has worked in the oil and gas industry since 1981, spending the first eleven years with Shell International as a reservoir engineer on field development projects, equity negotiations and operations in the UK, Oman, Tanzania and Holland. He then co-founded TRACS International in 1992, setting out to provide training and consultancy to the upstream industry. He built the business over time as Petroleum Engineer and Director, before taking on his current part-time role as Principal Reservoir Engineer.

He runs the SPE Short Course in Field Development Econmics, and has been an SPE Distinguished Lecturer in Risk Analysis. He is a guest lecturer at Heriot Watt Univeristy. He is co-author and editor of "Hydrocarbon Exploration and Production" (Jahn, Cook, Graham, 2008) and has written "Petroleum Econmics and Risk Analysis", published by Elsevier in January 2021.
