Abstract:
The qualitative assessment of the ability of a rock to produce fluid which could be hydrocarbon is very necessary. Data from five wells of central Niger Delta basin were available for this research. Interactive Petrophysics was the major software used for data analysis and processing. Microsoft Excel was also used for the computation of some petrophysical parameters. The research outcomes from the five wells showed that the most preferred sandstone reservoirs have met all requirements to be considered as highly porous and permeable. The mean porosity results from all the wells defined the formation as highly porous. They are strongly recommended for development and hydrocarbon exploration. Moreso, water saturation shows that the hydrocarbon potential is appreciable; Sand 1 reservoir actually has the highest transmissivity but the bulk volume of water is not constant, as such it is not homogeneous. However, all other preferred sandstone reservoirs are homogeneous as the BVW results are nearly constant and at irreducible water saturation. These findings indicate that the production of water-free hydrocarbon in the most preferred sandstone reservoirs is possible and in abundance. The rock properties are uniform in all direction with the flow medium that is evenly distributed.
