4D-Seismic All the Way - Implementing Time Lapse Reservoir Monitoring Globally

H-01 4D-SEISMIC ALL THE WAY - IMPLEMENTING TIME LAPSE RESERVOIR MONITORING GLOBALLY J.A. DE WAAL and RODNEY CALVERT Global Spread of Shell 4D Surveys 4 1 Introduction In the last 24 months Shell has made a focused global implementation effort to incorporate Time-Lapse Monitoring (4D) into the development of a large number of its fields. The aim of this ‘4D Implementation Thrust’ is not to maximise the number of surveys shot but to maximise the value extracted from the technology. This ‘implementation thrust’ has exceeded initial expectations and we discuss the activities the reasons for its success and results from
