Investment and decision analysis for petroleum exploration

  1. 1. Management And Financial Accounting In Oil and Gas Upstream Industry. Investment and Decision Analysis for Petroleum Exploration & Production Hamdy Rashed, CMA; CAPM Bsc of Accounting, E-mail: rashed.hamdy@gmail.com, Dated on July 10, 2012AbstractInvestment and decision analysis for petroleum exploration is a topic that manyexplorationists, geologists, management accountants and finance managers like to knowabout. This paper shows the major concepts of how investment, decision or project analysisis made for petroleum exploration in financial view. Such analysis depends on cash-flowmodels and applying capital budgeting techniques per International Oil and Gas businesspractices that consider accounting concepts, taxation, and contractual arrangement thatimpact on such analysis. This paper does not cover such analysis in technical view becauseit is out of specialization, but this financial analysis shall be made in conjunction withtechnical experienced staff to obtain some technical information of estimated reserves,estimated initial production, chance of success and others to enable Company to prepareinvestment and decision analysis.Keywords: Investment and decision analysis for petroleum exploration; Project Analysis forPetroleum Exploratio;, Present value of net cash flow in future for reserves, fair value ofexploration license.For Petroleum investment, decision or practices, the major risks that can be facedproject analysis, we need to consider the by Oil Companies, the input and output ofhome country taxation, production sharing the investment and decision analysis.and joint interest arrangements, andenvironmental legislations.

  22. 22. Comprehensive ExampleThe below data are variable input data that could be used in Cash-flow model. We will assumed that we have four licenses, onelincense is under exploration that a Company had three prospects to be drilled, two licenses are under study to acquire one of them orneither, one license is in development phase and another license is production license.The below cash flow model is simply prepared to provide our readers an overall idea of how to make investment or decision analysisfor petroleum exploration in brief: ‐ If we want to choose either to acquire license F or E, the below analysis can provide how much present value and expected monetary value are in both license, and IRR, payback, finding cost and breakeven point in daily produced bbl. Company may choose license E as long as it has not enough fund or its risk tolerance is small. ‐ Company has three prospects to be drilled in exploration license. Prospect C is not attractive because its net present value is negative, Prospect B is not attractive, however, its present value is in positive and it is about $9mm but the expected monetary value of prospect B is negative and its expected profitability index is less than 1. It its feasible for the company to drill a well in Prospect A, however, its probability of discovery is 7%, but its net present value and monetary value is positive, and all 22 
  23. 23. other indices such as IRR, PI, Finding cost, Breakeven points in daily bbl, and payback period encourage company to invest and drill a well in prospect APlease see next page that show the table of investment and decision analysis that is simply prepared. Cash-flow and decisionanalysis could be prepared in more complicated form that show the annual cash flow in separate column and compute the netreserves, net production, escalated oil prices and increased operation costs and tax more accurately based on tax laws, PSAs,JOAs. 23
