Abstract: A method for designing 4-D seismic acquisition source and receiver repeatability specifications, the method including: locating, with a computer subsurface anomalies above a target reservoir zone from analysis of high-resolution reflectivity images for the target reservoir zone; determining, with a computer, how the anomalies above the target reservoir zone modify target illumination for variations in the 4-D seismic acquisition source and receiver positions; and determining, with a computer, repeatability specifications for a monitor seismic survey, wherein tolerances for the source or receiver positions varies across an acquisition area based on how the anomalies modify the target illumination.
