Geologist & GIS Analyst |PDVSA |Venezuela |2005 — 2019

14 years supporting geospatial and subsurface workflows for oil and gas field development.

End-to-end geospatial and subsurface analysis across multiple field development projects — seismic interpretation, reservoir characterization, spatial database engineering, and cross-functional data delivery for production planning teams.

  • Performed seismic interpretation and subsurface modeling using Petrel, OpenWorks, and ArcGIS across multiple active field development projects.
  • Integrated well logs, core data, and 3D seismic surveys into reservoir characterization models used directly in production planning decisions.
  • Designed and maintained field-development spatial databases and geologic maps consumed by cross-functional engineering, drilling, and planning teams.
  • Improved reservoir prediction accuracy by 30% through advanced GIS workflow design and systematic integration of multi-source subsurface data.
