Abstract Integrated airborne and ground geophysical studies were conducted in parts of Ilesha schist belt, southwestern Nigeria. The goal was to provide a useful guide for mineral prospecting, with the hope of considerably narrowing down the future search for mineral deposits within the study area. Aeromagnetic and aeroradiometric data were analyzed for the reconnaissance study. In addition, the reduction-to-equator transform, analytic signal, tilt derivative, and Euler deconvolution filters were applied to the aeromagnetic data to enhance shallow and deep geologic features. The aeroradiometric data were used to determine spatial variations in the concentrations of uranium (U), thorium (Th), and potassium (K) in near-surface rocks and to map spatial lithologic changes. The 2D-magnetic sections, radiometric profiles, inverted resistivity, and induced polarization (IP) sections were generated from the integrated geophysical data. The electrical resistivity tomography (ERT) results reveal the subsurface heterogeneity (to a depth of approximately 197ย m) and varied geoelectric layers (topsoil, lateritic-clay, weathered rock, and basement rock). The IP sections show varying degrees of chargeability and features that suggest the presence of disseminated mineralized bodies concealed in some areas. The overburden thickness varies between 4 and 85ย m as determined from the 2D-magnetic and electric resistivity sections. Anomalous peaks on profiles of elemental ratios (eTh/K, eTh/eU, and K/eU) correlate with the results of IP and ERT. Data sets are well correlated and highlight areas with relevant structural and lithologic signatures favorable for mineral deposition. The methodology adopted in our research is well adapted, and the interpretation techniques provided insight into regional and local lithostructural settings. These anomalous areas are suggested as targets for future exploration works.

"Arise, awake, and keep moving on your way till you achieve your goal." With a 126-member-strong fleet of student members, the SPE Student Chapter at Indian School of Mines (ISM) Dhanbad, India, enjoys the credit of being the oldest student chapter in India. The chapter was established in 1988, but it was only a few years ago that all the students could join SPE, thanks to the Halliburton and Schlumberger student-sponsorship programs. Since its inception, the chapter has been quite active with programs offering student interaction with the industry. It regularly organizes guest lectures by eminent people from the industry.

I started my journey in ONGC as a young graduate trainee in 1977. I joined as one of a batch of 22 young graduate trainees from different disciplines at the Indian School of Mines, Dhanbad. I was posted in the newly formed Institute of Reservoir Studies (IRS) of ONGC. At IRS, I worked in the waterflooding lab, which provided firsthand experience on the flow of reservoir fluids through porous media. The institute was set up to carry out research on enhanced oil recovery (EOR) and oilfield development. The institute provided excellent opportunities for "youngsters" and had excellent peers who encouraged us.

Under the banner of SPECares the SPE Indian Institute of Technology Indian School of Mines [IIT (ISM)], Dhanbad, Student Chapter in India has joined hands with Sarthak, a unique mentoring program tailored to the needs of children from low income communities. In the pursuit of empowering millennials for a better tomorrow, the program started in February with 12 enthusiastic volunteers from the chapter as the leading change makers. Sarthak is a program initiated by the Aanandam Society for Sustainable Development, a non-profit social organization started by an IIT(ISM) Dhanbad alumnus in the Indian state of Bihar. A key motive of the group is to align mentoring as a lifelong learning tool. Sarthak works with many local educational initiatives in India that assist talented candidates each year from economically backward sections of the society and trains them for the IIT entrance exam, which has an acceptance rate of less than 1%.
ABSTRACT: Increase in subsurface temperature causes changes in physical & mechanical properties of rocks thereby causing instability in the strata which results in rock failure & surface subsidence. In this study, sandstone rock samples were collected from the Damodar River Valley of Dhanbad, India and have been subjected to laboratory experiments to evaluate the temperature effects on sandstone rock. Individual rock samples were given a heat treatment at a specified temperature. The temperature range of 200degC to 1200 degC is considered with the upper limit following the highest reported temperatures in the region. Under this heat treatment, the sandstone samples were first heated at a specified temperature for continuous 6 hours a day and 7 days. After this process, their physical properties (mineralogy, grain size and spontaneous imbibition by water and mechanical properties (Uniaxial compressive strength-UCS, tensile strength, ultrasonic wave velocities etc.) were determined in the laboratory. The result obtained shows that the temperature has a significant effect on the measured rock properties an attempt has been made to explain these changes using thin-section analysis. For example, the trend observed on UCS versus temperature crossplot suggest an increase in strength up to 400DegC and then decrease upto 1200 DegC. The initial increasing trend is attributed to the removal of moisture and change in compactness whereas the decreasing UCS trend is the result of the development of multiple fractures. These fractures enhance the secondary porosity and are evident in the thin sections heated to 600 degC,800 degC,1000 degC and 1200 degC. Because of the changes at the granular level, most of the physical and mechanical properties of the sandstone rock are influenced.
