Publication number: 20130289879Abstract: The application discloses a process and apparatus for characterising the evolution of a reservoir by co-analyzing the changes in the propagation times and seismic amplitudes of seismic reflections. The method comprising the steps of: providing a base survey of the reservoir with a set of seismic traces at a first time; and providing a monitor survey of the reservoir, taken at a second time, with a set of seismic traces associated to the same positions as in the base survey. The evolution of the reservoir is then characterised by inversion to obtain an estimate of the changes having occurred in the time interval between base and monitor surveys, the inversion being performed using at least some seismic traces for which no assumption is made that the energy is propagating vertically. In a main embodiment, inversion is performed by minimising a function which includes a term dependent on the incident angle of the seismic reflections.Type: ApplicationFiled: April 1, 2011Publication date: October 31, 2013Applicant: Total S.A.Inventor: Andrea Grandi
