RESERVOIR CLASSIFICATION AND PETROPHYSICAL EVALUATION OF “BAO” FIELD, NIGER DELTA

Demand for hydrocarbon and its products has been the major contributor to the economic growth of any nation. The costs involved in the exploration of hydrocarbons require adoption of suitable method for its processing and interpretation. This study is aimed to evaluate the petrophysical parameters in “BAO” field in order to classify the producibility of each reservoir in the study area. A suite of well log data from four wells in the study area is used to achieve this aim. Each well comprises of Gamma ray, resistivity and porosity logs. These logs were used to delineate five hydrocarbon bearing reservoirs in the study area. The delineated reservoirs are associated with varying petrophysical parameters, which were used to evaluate the storativity and producibility of the mapped reservoirs. The true vertical depths of the delineated reservoirs are 3318, 3418, 3482, 3550 and 3744 m, respectively. The analysis across these well sections revealed that each of the sand unit extends through the field and varies in thicknesses. The porosity and permeability values across the delineated reservoirs show that the pores have ability to store and transmit appreciable quantities of hydrocarbons, which will contribute to the reserve portfolio in the study area
