My name is Haozhe Zhang, but please feel free to call me Jason. I hold a bachelor degree in petroleum engineering with a minor in geology at the Univerisity of Kansas and I am a second year master student majoring in geophysics at K.U. as well. My current study is to use geophysical approaches to investigate the dynamic evolution of petrophysical properties in porous media during mineral precipitation. This study will advance our understanding in how geological variablity established through petrophysical evolution.
