Karen is a visiting phD student from Ceará Federal University for the 2019-2020 school year.  Karen has been working on her PhD research which uses a large dataset of 2D pre- and post-stack seismic reflection profiles, in combination with well logs to create an improved structural and stratigraphic framework in the deepwater Ceará Basin, located in the Equatorial Brazilian Margin.  She is working to improve reservoir prediction of complex sedimentary systems by classifying seismic lithofacies and with rock-physics. During her time with the School of Geosciences at  OU, Karen will be working with Dr. Bedle to perform additional seismic geomorphology, attribute analysis, and qualitative interpretation to further her research.
