ABSTRACT

Seismic reflection data obtained from 3D survey in part of the Niger-Delta basin, Nigeria was processed using Velocity Computation Software program (VELCOM), an interactive velocity analysis interpretation program. The application uses the principle of Apparent Velocity Picking, Normal Moveout (NMO) Correction and Stacking. Velocity intervals for 8 Common Depth Points (CDPs) were obtained. Interval velocity ranges between 1814 and 5579 ms^-1 and Stacking velocity (V_s) ranges between 1814 – 3639 ms^-1. Both velocities increase with depth, where interval velocity is more steeply than stacking velocity within the same interval depth. The result of this velocity analysis can be applied in NMO correction, calculating depths from reflection times, horizons identifications, the recognitions of lithology, detection of high pressure zone and migration.
