Economic Evaluation

Decisions can only be made if the difference between alternatives can be quantified. Economic evaluation provides the metrics to compare different development options. Income is generated from oil and gas production while expenditures are split in Capital Expenditures (CAPEX) and Operating Expenditures (OPEX). Cubes3 staff can build economic models and use them to generate key economic parameters used in decision making.


Fiscal Systems

Oil and gas developments are subject to various fiscal terms, which need to be modelled to calculate the economic parameters. The main fiscal agreements are Tax Royalty, Production Sharing Contracts and Technical Services Agreements. The models calculate how the revenues are split between royalties, taxes and profits and how these are divided amongst the companies and the state.  A thorough understanding of the fiscal terms is required to make the best investment decisions.

Oil and gas prices

The price is a (very important) input in the economic calculation. Prices may be based on existing contracts or on assumptions related to the demand and supply of oil and gas in the near and mid term future. Each company has its own independent view of future prices. Economists generally calculate the break even price for a development – i.e. Price at which the NPV =0-  to get a better understanding of the viability of the project.


Economic Parameters

The main economic parameters are:

NPV (dollars) – Net Present Value total cumulative cash flow at a chosen discount rate

IRR (%)– Internal Rate of Return, discount rate at which the NPV = 0

VIR (ratio) – NPV/CAPEX, profitability index  or value investment ratio at chosen discount rate

Cash sink (dollars) – maximum debt, before the project starts to generate income

Pay out time (years) – Time when cumulative cashflow goes from negative to positive (at chosen discount rate)

UDC ($/b)- Unit Development Cost, total CAPEX /total Production

UTC ($/b) – Unit Technical Cost, total costs (CAPEX + OPEX)/total Production
