dc.description.abstractGeomechanical characterization of a reservoir in the Niger Delta basin, using geophysical well-logs was adequately evaluated. The deformability and strength of delineated unconsolidated sandstone and compacted shale were investigated by determined elastic moduli (Poisson ratio, Young modulus, Bulk modulus, Shear modulus and Compressibility) and the unconfined compressive strength (UCS), cross plots of the parameters were done for validation. Sand production prediction was used to adequately analyse sanding. The results show average parameters of weakly cemented sand to have lower Poisson ratio, Young, Bulk, Shear modulus and Unconfined compressive strength of magnitudes of 0.28, 2.4GPa, 10.5GPa, 6.83GPa, 14.44MPa respectively, high compressibility (0.1 GPa-1), and porosity (0.25) the compacted shale have higher Poisson ratio, Young, Bulk, Shear modulus and rock strength as (0.35, 8.93GPa, 18.08GPa, 21.01GPa, 56.17MPa respectively, lower compressibility (0.06 GPa-1) and porosity (0.06). The shale has maximum average rock strength value of 56.17MPa.These results can be useful in the planning of well drilling and sanding prediction in the study area.en_US
