Abstract:With the ExlorationProduction maturity increasing in CNPC(China National Petroleum Corporation))'s operation blocks in Sudan, application of multi-survey merging technique in 3D seismic pre-stack time migration is becoming imperative. 3D multi-survey merging pre-stack time migration technique is an effective mean to reduce EP risk and to predict subtle reservoirs and the reservoirs which could be found out in the past. As the only domestic seismic data processing software, a mature 3D seismic data multi-survey merging processing module was developed in GRISYS processing system. Based on GEISYS system a mature 3D seismic data multi-survey merging processing workflow was also developed in Sudan Processing Centre (BPC) of GRI (Geophysical Research Institute) of BGP Inc., CNPC, the real multi-survey merging processing was realized in the workflow.
