摘要： Disclosed is a method of modelling a subsurface volume comprising the steps of: obtaining petrophysical data relating to valid geological and/or dynamical scenarios, converting this data into valid combinations of elastic parameters; projecting the valid combinations of elastic parameters onto a spherical plot; and determining a penalty term from the distances between each cell of the spherical plot and the nearest valid combination of elastic parameters within the subsurface volume. Valid geological and/or dynamical scenarios comprise those which are petrophysically possible. The penalty term may be used to constrain an inversion minimising a cost function associated with seismic mismatch between two or more seismic surveys.

摘要： Disclosed is a method for characterising the evolution of a subsurface volume. The method comprises providing a first and second surveys of the reservoir with a first and second sets of seismic traces, constructing an analytic filter operable to shift one or more seismic traces in dependence of a model parameter; and performing an inversion to obtain estimates of the model parameter such that the analytic filter aligns said first survey and said second survey. The analytic filter may be a plane wave destruction filter, and be such that the model parameter is a function of the analytic filter and is not a function of one or more of said second set of seismic traces.

摘要： Disclosed is a process for characterising the evolution of a reservoir that comprises non-horizontal layers, by analyzing the changes of at least the seismic amplitudes of seismic reflections. The process comprises 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 sets of seismic traces from the base and monitor surveys are then inverted to obtain an estimate of the changes having occurred in the time interval between base and monitor surveys, the inversion being performed using seismic traces for which allowance is made for the actual propagation paths through the non- horizontal layers of the reservoir.
