As a lead petrophysicist, I have worked on the detailed petrophysical characterization of siliciclastic and carbonate formations in various prolific basins of India and provided solutions to many challenges that we face while studying the complex reservoirs such as tight siliciclastics, tight carbonates, laminated and low resistivity reservoirs. I have strong operational understanding of logging tool physics across all service vendors, open and cased hole, wireline and LWD. Proficient in resistivity modelling, acoustic and image log data processing and interpretation. Well versed with downhole pressure and fluid analysis for estimation of fluid contacts and routine and special core analysis. I am well versed with the latest logging technology and leading Petrophysical Softwares in the market with excellent proficiency in Geolog and Techlog and hands on experience in Powerlog.

My research interest lies in Nuclear magnetic Resonance (NMR) logging measurements. NMR have been extensively used for characterizing porosity and pore size distribution with assumption of constant magnetic field gradient within porous media. However, internal gradients of magnetic field generated due to the presence of paramagnetic or diamagnetic centers such as clay particles can significantly affect NMR response and the resulting interpretation for pore-size distribution and porosity. There is, also, no systematic study on effect of clay distribution in rocks on NMR response documented in previous publications. Clays could be present in the rock matrix in the forms of structural shale, dispersed shale on the surfaces of grains, or within shale laminations. In my research, I will quantify the impact of internal magnetic gradients and spatial distribution of matrix components such as clay minerals on NMR response using pore-scale NMR numerical simulations. We also quantify the influence of the aforementioned parameters on the NMR-based evaluation of porous media.
