Pablo H. Gentil
Principal Engineer

Pablo H. Gentil joined DeGolyer and MacNaughton in 2021 to perform reserves and resources evaluations. Prior to joining D&M, Gentil worked at Repsol-YPF for 9 years and at ENI for 16 years, completing assignments in Europe, North America, and South America. He has over 25 years of experience in the industry.

Gentil graduated from Buenos Aires Institute of Technology (ITBA) in 1994, where he received his degree in petroleum engineering. In 2005, he received a master’s degree in petroleum engineering and geosystems from the University of Texas at Austin, where he developed capacitance resistance models and the Gentil model, now widely cited in data-driven reservoir engineering (844 citations, 377 in the past 5 years). He is also a 2021 alumnus of the Global Energy Leadership Program from Rice University. Gentil is a member of the Society of Petroleum Engineers and Society of Petroleum Evaluation Engineers. He is fluent in Spanish, English, and Italian and knowledgeable in Portuguese.

Major Projects

During his 20-plus years of international experience, Gentil has led multidisciplinary subsurface teams in high-caliber onshore, offshore, and arctic development projects. Prior to joining D&M, he acted as Reservoir Manager and Local Reserves Evaluator for Eni’s Mexico and Alaska Business Units. In Mexico, he led the multidisciplinary subsurface team that delivered Mexico’s first IOC development plan approved after the Energy Reform. In Alaska, he managed Nikaitchuq, one of the best performing viscous oil fields (waterflood in about 60 extended-reach wells), increasing production from 7,000 to 26,000 barrels per day. He also worked as Lead Reservoir Engineer for Galp, supervising reservoir engineering across Galp’s portfolio and supporting a divestiture process to secure funding for pre-salt Santos Basin developments.

Other roles at Eni included Reservoir Project Manager for the Belayim brownfield waterflood redevelopment project and Senior Simulation Engineer in the North Africa Studies group.

Gentil started his career at YPF, in Argentina, as a petroleum engineer with exposure to gas processing, drilling and completion, hydraulic fracturing design, and EOR projects. He had a relevant role in the debottlenecking of the Loma La Lata field, which achieved record production levels.
