    Co-Authors: N. P. Singh, S. P. Maurya, Kumar Hemant Singh
    Abstract:

    The present Log data study is aimed at evaluating the reservoir potentials of South Tapti Basin of India with limitation to the available data. A number of petrophysical Petrophysical parameters, i.e., effective Effective porosity Porosity (Φ), water saturation ( S _w), formation Formation water resistivity Resistivity ( R _w), hydrocarbon saturation ( S _o), and true resistivity ( R _t), are evaluated using the well log data Log data , and the reservoir characterization Characterization is performed. The analysis Analysis shows a Hydrocarbon-Bearing Zone in between 1866 and 1874 m, which contains gamma Gamma ray ( GR GR ) value of 34.4 API, resistivity of 117.3 Ω m, and average porosity of 35.7%. To know the fluid Fluid type in the reservoir Zone, neutron Neutron porosity and density Density porosity are plotted together and a crossover has been noticed at 1866–1874 m depth which indicates that the reservoir is filled with gas Gas . The analysis of petrophysical parameters and cross-plots shows that the reservoir is filled with sandstone Sandstone with some clay Clay content separated by shale Shale markers Markers , which act as seal rock for the reservoir.

  • Application of neural network modelling for classifying hydrocarbon bearing Zone, water bearing Zone and shale with estimation of petrophysical parameters in Cauvery basin, India
    Journal of Earth System Science, 2019
    Co-Authors: Atul Kumar Pandey, Rima Chatterjee, Biswajit Choudhury
    Abstract:

    This work has been developed to classify sand and shale from seven wells in the Cauvery basin using a multilayered feedforward neural network (MLFN) model. Seven wells distributed over 5100 km^2 of this basin have been utilized for analysis of conventional well logs and reservoir characterization. Hydrocarbon bearing sediments of Andimadam, Bhuvanagiri, Nannilam and Niravi formations of the Cauvery basin are evaluated in terms of shaliness, cementation factor, porosity, water saturation, and permeability. Pickett plot has been applied to investigate the cementation factor, formation water resistivity, permeability. The cementation factor ( m ) varies from 1.31 to 1.86 in these formations, whereas permeability varies from 0.01 to 400 md. Very good quality reservoir exists in the Bhuvanagiri formation with high permeability 300–400 md, whereas a good quality reservoir is occurring in Niravi, Nannilam and Andimadam formations with hydrocarbon saturation 60–70%.

  • Delineation using geophysical data of the hydrocarbon bearing Zone in the Begumganj structure, Hatia Trough, southern Bengal Basin, Bangladesh
    Journal of the Geological Society of India, 2013
    Co-Authors: Rashed Abdullah, Delwar Hossain, M. Rafiqul Alam
    Abstract:

    The Begumganj structure of the Hatia Trough in Bengal Basin has proved it’s hydrocarbon potentiality. Several seismic sections have been analyzed to construct different maps and to interpret subsurface geology, structure and stratigraphy. These maps reveal that the Begumganj structure is an elongated to oval shaped asymmetrical anticline having the general trend NNW-SSE. No major faults affecting the structure could have been identified. Most of the reflectors are strongly affected by channels, especially at the western flank. Based on the analysis of seismic and available well data, the only gas bearing strata at depth of 2995 m (or TWT 2.02 seconds) has been identified. The structure is interpreted as a strati-structure entrapment because shale fill channel truncated this layer on western flank and at the crestal part of the anticline. The structure probably formed after the deposition of sediments. The channel has formed after the corresponding unit cut has been deposited. The channels eroding the reservoir unit range from Late Miocene to Early Pliocene age where the anticline probably begun to form during the Pliocene. Strong increase in amplitude (bright spot), possibly associated with hydrocarbon, has been apparent on seismic lines BG 9 and BG 10. The stratigraphic succession based on the information of the wells drilled on this structure and it’s surrounding fields reveals that the lithological sequences range from Miocene to Recent age where the only proven gas producing sand Zone is located in the Bhuban Formation.
