Abstract

This paper presents a case study dealing with reservoir delineation and characterisation of the Basecopia field, part of Niger Delta Nigeria. The data set utilized for this work incorporate 3D seismic data, well log suites containing gamma rays, resistivity and porosity logs (neutron and density). These logs were utilized to focus petro-physical properties in three (3) wells. 780 inlines and 496 crosslines of seismic information covering an area of about 234 km2 were utilized. Faults were picked and correlated. Horizons of hydrocarbon bearing sands were picked in view of the re-suit from seismic- to-well tie. These were utilized to produce time and depth maps for a horizon keeping in mind the end goal to recognize the different basic highlights inside the field. Petro-physical aftereffects of the study demonstrate the dominating liquid found in the three wells is light oil at True Vertical Depth Sub Surface (TVDSS) of -7109 to -7333 ft. in Well A, -6916 to -7044 ft. in Well B and -7694 to -7858 ft. in Well C. Thereafter, seismic attributes such as the instantaneous frequency and the dominant frequency indicated the presence of channel filled sand containing hydrocarbon in regions around the wells. Hence, the wells can be said to be properly situated within the reservoir hydrocarbon bearing sand with spatial facies evenly distributed. The study however concluded that Well A bears a considerable amount of reserves of about 209.52Mbbls
