CEWELL is a premier institute which provides integrated petrophysical solutions to various Assets and Basins. CEWELL aids in preparing robust petrophysical models and provide inputs for risk reduction in E&P portfolio. This institute develops work flows for realistic evaluation of frontier exploration areas such as thin bed, Basement, Shale gas, Gas Hydrate, complex carbonate and low resistivity & low contrast reservoirs. It also generates valuable and valid petrophysical lab data viz. petrophysical parameters (a, m, n, mineralogical compositions) and magnetic resonance characterization for realistic pore volumes and producibility of reservoirs. This institute has been the nodal agency for geomechanical studies and building calibrated geomechanical models for reducing NPT and identifying sweet zones for well placement and planning effective stimulation jobs.
