The Bojude–Gadam area of Kwami Local Government Area, Gombe State, northeastern Nigeria, was investigated to characterize the subsurface and assess groundwater potential using geological mapping and ten vertical electrical soundings (VES) acquired with a Schlumberger array. The VES data were interpreted by one-dimensio...
Subsurface cavities in limestone formations poses hazardous risks to infrastructure from sudden ground movement, subsidence, and structural failure. These cavities form mainly from natural dissolution of carbonate rocks. Traditional methods like borehole drilling are costly, limited in resolution, and require many bore...
The following abbreviations are used: acoustic borehole televiewer (ABI40), uniaxial compressive strength (UCS), factor of safety (FoS), two-dimensional finite-element program RS2, and three-dimensional finite-element program RS3. The stability of deep open-pit slopes is governed by structural heterogeneity, rock-stren...
Caprock integrity is a critical requirement for the safe and long-term geological storage of CO₂, yet its assessment remains challenging due to extremely low permeability, strong mineralogical heterogeneity, and the limited availability of representative core samples. In particular, the influence of petrological proper...
Salt (halite) massifs undergoing active dissolution are among the most hazard-prone geological settings for ground instability, and their monitoring requires a reliable geometric model of the salt body and its overburden. This study presents an integrated geoelectrical–geological characterization of the salt formation...
Reliable geomechanical modeling for hydraulic-fracture design in horizontal laterals is constrained by limited data availability. The full petrophysical log suites necessary for accurate modeling increase rig time by 2–4 days and are often impractical to obtain in highly deviated wells. As a result, gamma ray (GR) me...
