Quantitative Assessment of Connectivity across a Fault Using 4D Seismic

A037 QUANTITATIVE ASSESSMENT OF CONNECTIVITY ACROSS A FAULT USING 4D SEISMIC Summary 1 YAHYA ALMASKERI AND COLIN MACBETH Heriot-Watt Institute of Petroleum Engineering Edinburgh UK EH14 4AS A 3D geological model is built within which two producing horizontal wells and a normal vertical fault are placed. This scenario is then used as a test-bed to investigate how the 4D seismic might be related to different degrees of fault seal. A reservoir simulation is run and the 4D seismic response computed. The full and limited-offset stack amplitudes at the top reservoir respond similarly to the pressure differences and oil saturation changes
