He has extensive experience in igniting step-changes in technology management and integration loops in research and applied research. With a decades-long, intensive and successful career advancing transformation paths in basin exploration, field development, digital transformation and technology piloting loops for large National Oil Companies in Latin America and the Middle East, he grounds his success in a unique ability to lead complex, multicultural, and large teams into specific goals. He is passionate about advancing energy transformation loops and is now centering his consulting around the technological applications needed for decarbonization, CO2 Storage and Monitoring, Emissions Monitoring, and innovations related to ESG reporting which are relevant specifically for the  upstream segments of the Oil and Gas sector. His expertise also includes Geosciences applied to Water Management, Mining and CCUS.

His acute insights started early on in his career, and notably, his celebrated PhD thesis on the resistivity of thin layers constitutes the platform of today’s progress in subsea and borehole detection of oil reserves, CO2 monitoring, and ground water management, in an approach that is now feasible due to the utilization of new materials and miniaturization of instrumentation.

In addition to a hands-on leadership experience in the corporate world of oil and gas, Dr. Passalacqua has built a solid and renown experience in academia, having taught as Associated, Invited and head Professor in Venezuela (Universidad Central de Venezuela, Universidad Simon Bolivar), USA (Colorado School of Mines), and Kuwait (Australian College of Kuwait, and Kuwait University).
