Abstract: Uphole refraction survey of the velocity regimes in South-Eastern part of Niger Delta, Nigeria was carried out using a 12-channel seismograph: Mc SEIS 160M Model 1115. The study presents a regional weathering structure of the area, the velocities and depths of the weathered layers were calculated from the travel time of the seismic waves. The data were interpreted using the time – intercept method which revealed that the low velocity layer was fairly variable in thickness in the region, varying between 24.5m and 25.8m, with a regional average value of 25.12m. The weathered and consolidated layers have average Compressional wave velocities of 944.0m/s and 1907.69m/s respectively. The knowledge from the result of this study can be applied in oiland ground water exploration plans.
