Abstract:
1. A method comprising: receiving a first set of seismic data indicative of measurements of a producing field acquired in a first towed seismic survey having associated first streamer positions; receiving a second set of seismic data indicative of measurements of the producing field acquired in a second towed seismic survey having associated second streamer positions that do not coincide with the first streamer positions; receiving a third set of seismic data indicative of measurements of the producing field acquired in at least one intervening towed seismic survey conducted after the first towed seismic survey and before the second towed seismic survey, said at least one intervening towed seismic survey having associated streamer positions that coincide with the first and second streamer positions; and processing the first, second and third sets of seismic data in a time lapse analysis of the producing field.
