    Basement Depth and Sedimentary Velocity Structure in Gongola Basin
    Author(s): Epuh EE and Joshua EOEpuh EE and Joshua EO

    Basement depth in the Gongola basin is found to be much deeper than previously supposed. Gravity modelling of the upper Benue Trough, Nigeria revealed thick sedimentation with maximum values within the range 5.2 km-7.0 km. This is in contrast to the average value of 5.0 km suggested by earlier studies. Gravity modelling across the basin was carried out to determine the basement depth using the second vertical derivative as input anomaly profile. The seismic modelling process in this research involves the determination of the distribution of seismic velocity using the: depth-normalized velocity iteration technique, check shot and sonic log curves. The integrated depth algorithm (IDA) iterative process was adopted in the determination of the interval and depth normalized interval velocities to adequately address the depth conversion for the determination of the lithology of the basin.
