  Dy, Supdt. Geophysicist

  Started my career with ONGC, India as Geophysicist. My experience in ONGC spans across acquisition, processing (2D/3D) and Integrated Interpretation of seismic data on workstation.I have the credit of detailed seismic Interpretation of 2D/3D project in both clastic and carbonate regime which resulted in four successful exploratory locations.I have the credit of interpreting Vietnam offshore data (Post rift sequence evaluation, Nam Con Son basin) got under contract from BP. The work was highly appreciated by ONGC management and BP.1996 - 1999 : As Deputy Seismic field Party chief worked in thrust belt of NE India. Planning and acquisition of land seismic data and VSP.
