As the global energy industry continues to feel pressure to meet the increasing demand for a low-cost, reliable energy supply, and for meeting the increasingly legislated net-zero requirements, it is critical that all corporate functions evolve to meet this new reality. Our operational colleagues, engineers and geoscientists, have been fundamental to advancing the ability of the industry to achieve these increasingly difficult requirements for the last 30 years. However, the finance function has significantly lagged, relying on a 30-year-old technology (Excel) to undertake their role in the risk analysis and value creation process. How does the finance function now evolve to enhance their role in meeting the increasing demands on the industry – through using a probabilistic approach in its financial models, risk analysis and transaction execution tools.
