The following structure would be a good approach:

Information that can be shared if inquired:

• The rights being offered to Liquid Energy give them the right to drill for 1 year and produce oil for 20 years.
  Assume that no oil is produced until the beginning of year 2.
• Liquid Energy can get the drilling operator to deploy a maximum of 10 rigs in each of the regions.
• The cost of the rig day includes crew, consumables, and services.
• Any amount of oil being extracted will be sold at the spot market price of the moment.
• For simplicity assume that the oil wells will produce the same amount of oil for the next 20 years with no maintenance costs.
• The rights to extract oil cost $40 m annually in each region.

First, the interviewee should try to understand how to evaluate and decide which region would be the best fitting later on.

Information that can be shared if inquired:

• Spot price = $50/Barrel

Here the interviewee should evaluate which region is most profitable.

The answer will be a function of the investment, variable costs, and quantity of oil extracted by field. This last variable will depend on the number of wells drilled in one year.

Diagrams 2 & 3 should give the interviewee enough information to identify the number of wells and the amount of total oil that could be extracted from each field, as well as the yearly production per well.

The result of these calculations should lead to the conclusions in the last step.

The interviewee should conclude and present which option would be the best one:

• Liquid Energy should invest in buying the rights for Region 2.
• It is important to recognize that even though the profit margin for Region 1 is significantly higher on a per well basis, the return of the investment depends on the total number of wells that you can drill in the first year and the upfront cost for the rights to extract oil in each region.
• Additionally, the interviewee should be able to identify other qualitative aspects of the investment that might affect the decision to invest in a certain region.
• An excellent answer would mention and briefly summarize the impact of including an expected value analysis, which would assign different probabilities of extracting the expected barrels per day

There are also other factors that could impact the decision to invest:

• Insurance costs
• Political stability of the region - Labour contracts and unions
• Volatility of oil prices
