摘要： Disclosed is a process for characterising the evolution of a reservoir by co- analyzing the changes in the propagation times and seismic amplitudes of seismic reflections. The method comprises the steps of: providing a base survey of the reservoir with a set of seismic traces at a first time; 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; and characterising the evolution of the reservoir by inversion to obtain an estimate of the changes having occurred during the time interval between base and monitor surveys. The inversion is regularized by the imposition of a sparsity constraint, such as Cauchy sparsity, which favours inversion solutions for which most of the solution values are equal to zero, while large values of said inversion solutions are preserved.

摘要： Disclosed is a process for characterising the evolution of a reservoir over a time lapse comprising the steps of: providing a base and a plurality of monitor surveys of the reservoir, each having a set of seismic traces at different times; deriving an optimal regularisation weight-map from a combination of at least three surveys; and using the optimal regularisation weights to invert and obtain an improved time lapse seismic image between pairs of seismic surveys.

摘要： 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.
