Abstract :
The aim of this work is to investigate the
geophysical borehole logging of extreme Owa region (Delta
State - Nigeria) with a view to determining the lithology of
the area. The resistivity of the formation was carried out,
using resistivity logs of short Normal (SN), long Normal
(LN), and long lateral (LL). The results show that the
interval between (0-12) m bears loose lateritic sand. The
depth zone of (24-30) m, (30-49) m and (55-58) m consist of
clay rich sandy stones, which is capable of bearing water.
The intervals (110-116) m to (158-160) m shows whitish
colour particles with light brown silty clay. Within the depth
intervals of (62-78) m and (92-102) m with formation
resistivities of maximum values up to 6500 (nm) and 6100
(nm) respectively. The interval (78-92) m with moderately
low resistivity between (700 and 2400) m has moderate water
bearing aquifer (clay sandy zone).
