Reservoir characterization of an x-field, offshore Niger Delta, Nigeria, using well data

Petrophysical parameters of an oil field in the Niger Delta, Nigeria, were analyzed and characterized using well log data. The data used to determine hydrocarbon depth (2757 3591 m) lithology field. Shale volume (Vsh) was calculated linear Larinov equations while Archile equation water saturation. study revealed saturation 0.035 0.426 good porosity range 0.105 0.152. bulk ranged from 0.005 0.049 0.067 0.130.  Hydrocarbon 0.574 0.965 estimated across reservoirs. value moveable (Shmov.) is less than 0.70 therefore inferred be moveable. well-seismic tie synthetic antithetic growth faults, roll-over anticlines, back-to-back collapse crests as major faults area, trending NW-SE.  model horizon obtained for shows that eastern part with maximum contour closures corresponds area accumulation. Key words: properties, characterization, saturation, hydrocarbon, shale volume, lithology, potential.
