Globally the challenge to meet the increasing energy demand is on with the application of game-changing technologies to maximize recovery from proven reserves in mature assets. Production studies have shown that some Niger delta fields have heterogeneous reservoirs with low to fair recovery factor derived in most cases by software simulations without adequate field acquired reservoir parameters before embarking on the secondary development plan for such reservoirs. Failures recorded in most secondary recovery strategies for heterogeneous reservoirs are accountable for lack of in-depth studies of the reservoir characteristics. There is a direct relationship between reservoir recovery factor and the petrophysics of the reservoir. A sand body in the field can exhibit variable petrophysical changes at different positions in the field. Therefore optimum secondary recovery plan for such reservoirs are designed with the combination of field acquired (not simulated) petrophysical data (porosity and permeability), the environment of deposition, special core analysis and formation evaluation studies. This study emanates from the recently developed project in a field in Niger delta.
