RE:RE:RE:Frontera Metrics (worth a look I think) If you've seen my LinkedIn then you know I'm speaking from experience. I've been part of teams pitching development scenarios and justifying economics to my own c-suite at the time as well as to partners and potential partners.
Business development is done in teams consisting of technical experts quantifing risk and value. It's up to the C-suite to approve or deny recommendations.
Many times I would run economic ranges assuming flat oil prices between $50-80/bbl as well as the strip price. To give management a flavor of how quickly things could change based on market conditions.
Good news for Guyana so far has been that projects tends to breakeven in the $30s/bbl range.
