supply Analyst/arbitration

Dr. Sandrea is an oil and gas supply analyst and has been an expert witness in multi billion dollar Arbitrage E&P disputes.


Dr. Sandrea has developed the Opportunity Index for comparing the relative attractiveness of investments in upstream projects as well as the attractiveness of a company’s E&P portfolio in different countries. The model integrates industry standard risk indexes and offset indicators, such as, potential oil and gas reserves, F&D costs, and company financial performance into a single composite index. More recently (2017), he developed an Upstream Financial Opportunity Index to select bid prospects.
