Norman, OK


Geophysicist Intern, Geophysical Insights, Houston, TX Jun 2020 - Aug 2020
• Correlated well logs for well tops definition and development of a stratigraphic framework in deepwater deposits.
• Applied artificial neural networks for lithofacies prediction using well log data.
• Calculated and interpreted seismic attributes to define optimal combinations to be used in machine learning workflows (self-organizing maps)
• Applied machine learning for seismic facies interpretation and reservoir quality estimation
• Created a full and functional training dataset that included well logs, well tops, seismic horizons, and attributes to be used in Paradise machine learning workflows.

Geoscientist Intern, Tapstone Energy, LLC, Oklahoma City, OK Jun 2019 - Aug 2019
• Integrated geology and production data to characterize the Meramec strata, Anadarko basin-OK
• Created and interpreted subsurface correlations using well logs to build the stratigraphic framework.
• Performed ANN (machine learning) to predict facies using core and well-logs for 3D facies modeling.
• Built and analyzed seven 3D reservoir models and created more than 50 reservoir maps to determine main drivers in production to define prospective areas.
• Provided play analysis for drilling and development of the play

Project: Reservoir quality from sequence stratigraphy, facies modeling, and production performance of the Meramec, NW STACK, Oklahoma.
