Research Interests

Dr. Bhattacharya’s primary research activities focus on geophysics, petrophysics, and 3D subsurface modeling. He is interested in quantitative rock property estimation and multi-scale subsurface characterization using 2D/3D seismic, well logs, and reservoir data. He uses various techniques, such as seismic attributes, forward seismic modeling, seismic inversion, joint petrophysical inversion, and coupled fluid flow-geomechanical simulation for his research. In addition, he implements different types of advanced machine learning and geostatistical algorithms for facies, fracture, and rock property classification, prediction, and modeling.

Geographically, his past and current research areas include different conventional and unconventional reservoirs in the Williston (North Dakota), Permian (Texas and New Mexico), Appalachian (Pennsylvania, Ohio, and West Virginia) basins, Mid-Atlantic offshore, and Alaska.

Currently, his broad research themes are:

1. Energy Resources Exploration and Development (Conventional and Unconventional)
2. Application of Predictive Data Analytics in Geosciences
3. Induced Seismicity
4. Fluid Storage and Utilization (Enhanced Oil Recovery)
