Highly motivated Petrophysicist with strong technical experience in clastic and carbonate reservoirs working across a broad range of operational and reservoir description roles. Expertise in exploration and development stages and experience in conventional and unconventional (shaley-sand, naturally fractured, shale gas/oil and tight sand) reservoirs. Successful record of work on international projects for the Exploration Appraisal and Business Development teams in several unconventional shale gas/oil and tight gas/oil sand projects including several US, Mexican, Colombian, Argentinean and Bolivian basins.  Solid technical and team-oriented skills with demonstrated success in complex lithology reservoirs in onshore and offshore basins, integrated reservoir characterization projects and field development and well workovers.

• Advanced petrophysical evaluation in conventional and unconventional complex lithology reservoirs. Experience with siliciclastic and carbonate reservoirs including shaley-sand, shale oil and gas, tight gas/oil sand, and naturally fractured reservoirs.
• Integration of core, log, and fluid data to deliver a comprehensive reservoir description analysis.
• Experience in petrophysical operations, including: designing coring, wireline and logging while drilling programs, and witnessing logging/coring operations.
• Strong knowledge in log quality control procedures, processing and interpreting logging data.
• Experience working with RCA and SCAL to aid well-log interpretation, including a deep understanding of core analysis techniques in shale source rock reservoirs.
• Rock typing, permeability predictions and saturation height modeling.
