Esteban DÍAZ PANTIN
Esteban is a geophysical engineer who graduated from Universidad Simón Bolívar (USB) in Caracas Venezuela, in 2008. After obtaining his Bachelor of Science degree, Esteban worked in seismic data processing, depth imaging, as well as research and development. Esteban joined CWP in Fall 2011. During his time at CWP, he has worked on migration velocity analysis using two-way operators. He has completed two internships, one each with BP America Production Co. and Total E&P Recherche Développement. Both internships focused on full waveform inversion (FWI) projects.
Outside of geophysics, Esteban enjoys playing volleyball, tennis, soccer, skiing and exploring Colorado and neighboring States.
Esteban's main research interest is Migration Velocity Analysis (MVA). At CWP, he studies the kinematic information contained in surface seismic data and seismic images. Esteban looks into different misfit errors functionals in both image and data domain, that improve the robustness of tomographic operators. His objective is to close the gap between high and low resolution tomographic methods.
