The study aims to investigate the impact of source charge size and burial depth on the quality of onshore seismogram data in the Niger Delta, Nigeria. Dynamite charge sizes of 0.4kg, 0.8kg, 1.2kg and 2kg were used as energy source and detonated in drilled holes at 15m and 40m. Through a thorough analysis of various parameters, the study found that both source charge size and depth of burial significantly affect the quality of seismogram data. The results showed that increasing the source charge size leads to an increase in the amplitude and signal-to-noise ratio, while increasing the depth of burial decreases the amplitude and increases the frequency content of the recorded seismograms. Moreover, a strong correlation was observed between source charge size and depth of burial, indicating that the two parameters cannot be considered independently. These findings have important implications for seismic data acquisition and processing, as they highlight the need for careful selection and optimization of source charge size and depth of burial to achieve high-quality onshore seismogram data in the Niger Delta region. Overall, this study provides valuable insights into the factors that influence the quality of seismogram data and can aid in improving the accuracy and reliability of seismic data interpretation and analysis in the oil and gas industry.
