ABSTRACT: Seismic data were
integrated with well log to define the subsurface geometry and hydrocarbon
trapping potential of Owem field, onshore Niger Delta. The research methodology
involved horizon and fault interpretation to produce subsurface structural map.
Wireline logs signatures were employed to identify hydrocarbon bearing sand and
compute reservoir petrophysical parameters for hydrocarbon reservoir analysis.
Two horizons HA and HB were identified and mapped and a time structural map was
produced. Two reservoirs R1 and R2 were delineated in the wells A and B. The
computed petrophysical parameters for well A showed that the thickness of
Reservoir R1 and R2 are 11.5 and 12.5 meters respectively while the porosity
and hydrocarbon saturation varies between 0.16 - 0.24 and 0.6 - 0.8
respectively. Similarly the average thickness and porosity of R1 and R2 for
well B is about 18.0 meters and 0.12 while the hydrocarbon saturation varies
between 0.7 - 0.8. The integration of seismic and well logs data has proved to
be a useful tool in the reservoir analysis of hydrocarbon.
