The prompt

Dunewell Petroleum (a fictional company) can develop an onshore field with 100 million recoverable barrels. Development capex is USD 1,200 million. Lifting cost is USD 9 per barrel and transport is USD 3 per barrel. The government takes a royalty of 20 percent of the oil price. The field would produce 10 million barrels a year. What is the full-cycle breakeven oil price, and what is the yearly cash margin at USD 70 per barrel? Ignore income tax and the timing of cash for now.
