Curriculum Vitae


Nishant received his Bachelor's and Master of Science degrees in geophysicsat the Indian Institute of Technology-Kharagpur in 2008. He worked as an On Board Processor for Schlumberger for two years before starting graduate studies at the Colorado School of Mines with a minor in mathematics. He worked on FWI for 2D (elastic) VTI media to estimate vertical velocities and anisotropy parameters. Nishant interned with Shell International Exploration and Production, in Houston, Texas, in the summer of 2012. The work involved testing various parameters for serial- and joint-inversion (FWI) of acoustic (OBN) data and analysing the tradeoff between inversion parameters. In the summer of 2014, he interned with BP and worked on FWI testing for different model parameterizations on synthetic and real data.

In April 2016, Nishant successfully defended his PhD thesis at the Colorado School of Mines. His thesis, titled "Full-waveform inversion for VTI media" was defended under the guidance of his advisor, Prof. Ilya Tsvankin. Nishant is currently conducting post-doctoral research at CWP.

His hobbies are hiking, reading, playing tennis and experimenting in the kitchen.

 

Research

Nishant worked on Full-waveform Inversion (FWI) to estimate Thomsen parameters (vertical P- and S-wave velocities, epsilon and delta) in 2D VTI media. One of the ways of understanding the trade-offs seen in the inversion results is by obtaining the 'radiation pattern' for a given parameterization. The insight gained from this can be used to choose an appropriate parameterization when inverting for a complex model. He also worked on a 2D synthetic model based on the geology of the Valhall field.
