![]() For stress tensor analysis, the study confirmed the defining condition of Sv > SHmax > Shmin as normal fault, which is fault regime prevalent in the study area, in line with Andersen’s classification. The crossplots of Poisson’s ratio versus compressional velocity are expressly well-defined and exponentially decaying with the compressional velocity, indicating an inverse relationship between the two (2) parameters. The bivariate crossplots of heat production and Young’s modulus indicated that the amount of heat produced by the shaly materials affects the elastic properties of the reservoir units and flow rate. We estimated several geomechanical parameters, which include, but is not limited to, Young’s modulus, Poisson’s ratio, bulk compressibility, unconfined compressive strength (UCS), shear modulus, heat production, vertical stress (overburden), minimum horizontal stress, maximum horizontal stress, shear stress normal to fault plane, shear stress in direction of dip, and shear stress in direction of strike. ![]() Three (3) reservoir units were delineated from these wells that falls within the hydrocarbon windows (Agbada Formation). A suite of well log data were interpreted, reservoirs were identified and correlated across three (3) wells and their geomechanical parameters computed from empirical relations. ![]() Reservoir geomechanical parameters in “Tobi” Field, Niger Delta were estimated using well log data with the intention of improving reservoir characterization and establishing stress regime of the field.
