E-mail: aknaak@mines.edu

 

Ali earned a Bachelor of Science degree in physics and mathematics from Presbyterian College in Clinton, South Carolina in 2010. She is working at CWP with Professor Roel Snieder on applying synthetic aperture to controlled-source electromagnetic (CSEM) data. Ali is also collaborating with Professor Jen Schneider in the CSM Liberal Arts and International Studies (LAIS) Department for her minor on topics concerning communication and context of geophysics. Ali's academic interests are in improving CSEM, communicating science, mathematics, and physics.

Her hobbies are road biking, hiking, playing disc golf, reading and volunteering at the local animal shelter. She loves working, playing, and living near the mountains.

 

Research

Ali's topic of research is applying synthetic aperture to controlled-source electromagnetics (CSEM). The use of synthetic aperture with CSEM increases the response of a hydrocarbon reservoir. She has demonstrated the benefits of steering the field in 3D in the inline and crossline directions and have measured improvement of detectability from a synthetic data set. The next step in Ali's research is to develop an optimization scheme to optimize the steering parameters of the synthetic aperture.

single_source

Ratio of the absolute value of the inline electric component with and without the reservoir for a single source

synthetic_aperture_source

Ratio of the absolute value of the inline electric component with and without the reservoir for a synthetic aperture source

steered_synthetic-aperture_source

The ratio of the absolute value of the inline electric component with and without the reservoir for a steered synthetic aperture source (average ratio in the dashed box is 2.06 which is an over 100% anomaly from the reservoir for the steered synthetic aperture source)
