a reservoir characterization and potentiality of economic viability: a case study of k-creek oil field in niger delta.

In an attempt to solve some oil industry exploration problems, such as drill misses, erroneous forecast in field development plans (fdp’s) etc., a case study was done on k-creek oil field in a central swamp depositional belt of the niger delta basin. both qualitative and quantitative reservoir characterization were deployed on the field, using suite of well log that consists of gamma ray, resistivity, sonic, neutron, and density, 3d seismic, and checkshot data to analyze and evaluate the rock and petrophysical properties of the field. the effective porosity across the reservoirs ranges from 3% to 32.68% in the sands a to l. the peameability of the reservoir units’ range was from 375.21 to 2108.74md. this implies that the permeability varies from very good excellent. water saturation estimated from the reservoir sands ranges from 12.91% to 81.99% in sand a to l, while the hydrocarbon saturation of the reservoirs was 18.01% to 87.09%. three synthetic structural building listric faults were interpreted across the inlines intercepting the top of reservoir sand a001 and b001. these three-synthetic structural listric faults (f1, f2 and f3) intercept the top of the selected reservoirs. the structural trapping mechanism of the reservoirs are synthetic fault assisting structures otherwise called rollover anticlines. the hydrocarbon reservoirs in k-creek field are economically viable for hydrocarbon production as exemplified from the results of the porosity, fluid saturation and permeability values, and also the overall analyses carried out in this work.
