Juan Francisco Arminio

Geoscience Advisor

Senior Geoscience Advisor at U3 Explore, G&G Manager at New Stratus Energy, and Associate Professor at Universidad Simón Bolívar. Geoscientist with extensive experience in exploratory analysis and integration, passionate for new technologies applied to solve geotechnical challenges. Skilled in uncertainty reduction and functional play visualization for exploration and production of hydrocarbons, and subsurface container characterization.

More than 30 years of experience as a geoscientist,with a track record in frontier and backyard play-based exploration, and integrated reservoir management and studies for both new and mature oil and gas fields and business development of subsurface assets.

Passionate about effective teamwork as  key vector to idea creation and case-specific workflow design, with flexibility to apply regional–to–local scale geoscience in exploration, production, new ventures, and decarbonization projects.


  • Integrate geophysical, geological, and geochemical data to evaluate petroleum systems, define exploratory prospects, assess their key volumetrics, and estimate associated exploratory risk and geological uncertainty
  • Carry regional to local scale geophysical and  geological risk assessment of lithologic seals and other key petroleum system components for oil and gas reservoirs and exploratory leads and prospects  and injection of gases and water.
  • Visualize geological plays and construct predictive subsurface models to support critical decision-making in the context of subsurface resource projects, including oil, gas, and decarbonization projects.
  • Define basin-scale tectonostratigraphic frameworks using and integrating data from seismic surveys, potential fields, surface geology stratigraphic trends, legacy information, exploration record, and petroleum system analysis in order to support gross depositional models and play fairways for reservoir, seal and source systems, basin compartments and geopressure regimes.
  • Evaluate and assess production, exploration and decarbonization business ventures in the context of government bid rounds and business farm-ins, bidding assessment, and evaluation
  • Carry G&G reviews of mature oil and gas  fields in the context of energy transition–focused projects for CCS, ultimate recovery optimization and technology-supported asset  re-exploration
Geographycal G&G Experience


  • Creative and enthusiastic, self-motivated and passionate about geosciences and related new technologies.
  • Natural integration skills, facilitated by his long run of basin analysis in multiple countries of South and Central America, Africa, and Europe.
  • Proven team-building skills, focused on optimizing performance and output of team members regardless of technical specialty
  • Life-time passion for nature, with a special interest in the geological, botanical, and zoological exploration of pre-Cambrian terranes of Venezuela and Colombia

Juan F. holds a MSc. in Basin Evolution and Dynamics and a Diploma in Geology from Royal Holloway University of London,a Geological Engineering degree from Universidad de Oriente of Venezuela and Integrated Reservoir Management from the Institut Francaise du Petroleo, Paris.

He started his career with Maraven S.A., an affiliate of PDVSA, moving through career – development positions in production, exploration and drilling engineering. Exploration assignments included Maraven´s  exploratory campaign of the North Merida Andes thrust front, with a two – year spell of post-grad studies awarded by the Company. After that, mature reservoir modeling and re-appraisal, and finally leading a multi-discipline team to study new exploratory plays in mature fields in the Maracaibo basin.

With PDVSA took part as Senior geoscientist in Shared – Risk Contracts that carried exploration in Eastern Venezuela´s Gulf of Paria and led the Exploration Intelligence unit in charge of new frontier plays and geo-strategic studies.  

Upon moving to Colombia, took active part as Technician and Exploration Manager in the successful Colombian exploration run of Pacific Stratus (later Pacific Energy and Frontera Energy). Also, managed exploration projects in Peru, Guatemala and Brasil.

In 2001 he founded the Exploration Geology courses at Universidad Simon Bolívar´s Department of Earth Sciences, which he has been teaching with a research focus on play visualization and risk analysis and uncertainty reduction.
