Abstract
The Campano - Maastrichtian Gombe Sandstone of the Gongola Basin of the Upper Benue Trough is composed of arenaceous lithology that is laterally extensive and has reached a thickness of over 300m. The petrophysical evaluation of the formation on the basis of bivariate plots, petrographic analysis and falling head permeability indicated average porosity values of 15%, 33% and 23% respectively. Average permeability values of 5.2D and 100md were also obtained from bivariate plots and falling permeameter analysis respectively. These values are comparable to the reservoir rocks of proven petroleum basin of the North Sea and Niger Delta. Therefore, the Gombe Sandstone can serve as a potential reservoir rock in the Gongola Basin.
