The Economic Value Proposition Matrix® (EVPM) model was initially used to conduct an Independent Verification and Validation (IV&V) as a consulting engagement for a Super Independent oil and gas company assessing the CAPEX for a digital oilfield implementation for an old brownfield—circa 2004. Its development basis is taken from our industry sponsored 2004 study, Roadmap to Enterprise Optimization: A Guide to the Impact of Information Driven Field Operations on the Petroleum Corporation. EVPM well proven and has been in continuous commercial use and upgrade since then.
