Accelerated Weight Drop(AWD)seismic source and its application in the exploration of shallow target layer

In conventional seismic acquisition domain,very few applications used Accelerated Weight Drop(AWD)seismic source were conducted in recent years due to low energy level,connection problem with acquisition instrument and DGPS signal real time monitoring,etc.Accelerated Weight Drops were successful applied in sensitive operational area and received qualified seismic data in the high density seismic program which carried out by BGP in Uganda.Key technical points and applications of Accelerated Weight Drop are analyzed& discussed systematically in this paper from the aspects of configurations,working principle,time sequence,organization,data quality,etc.
