Petrophysical Charaterization of the Kwale Field Reservoir Sands (OML 60) from Wire-line Logs, Niger Delta, Nigeria
Well log data from the deep parts of the six wells located in the Kwale
field of the Niger delta basin (OML 60) were used in the determination
of some Petrophysical characteristics of the reservoir sands. Well log
data were obtained from sonic, gamma-ray, matrix density and
resistivity logs. The petrophysical characteristics investigated were
porosity, water saturation and permeability. The results of the
analysis revealed the presence of twelve sand units. Correlation of
these sand bodies indicate that the reservoirs consist of stacked
barrier bar and point-bar sandstones. The thickness of each sand unit
is highly variable, ranging between 5.0 and 95.0 m. Average
shale-corrected porosities vary between 11.0 and 19.0 percent and
generally decreasing with depth. The average water saturation of these
units vary between 52.5 and 88.5 percent. These values are generally
high for the sand units in wells 2, 5, 6 and 8. Similarly, the average
permeability values vary between 3.2 and 28.0 mD. This study is a first
attempt to make available Petrophysical data for the reservoir sands in
the Kwale field of the Niger delta basin. The results of this study
will also enhance the proper characterization of the reservoir sands.
However, other sources of confirmative and collaborative investigations
will therefore be essential and consequently will be the focus of
another study @ JASE
