    • Evolution of an hydrocarbon reservoir in the process of producing is carried out by co-analyzing the changes in the propagation times and seismic amplitudes of a seismic wavelet along propagation paths in the ground. A base survey of the reservoir is provided, with a set of seismic traces at a first time T associated to a first velocity field Vb; a monitor survey of the reservoir is provided, the monitor survey being taken at a second time T+ΔT, with a set of seismic traces associated to the same positions as in the base survey; the monitor survey is associated to a second velocity field Vm. For a set of points i in the base survey, one computes over the points of the set the sum S of a norm of the difference between the amplitude bi of the seismic trace in the base survey at each point i and the sum of the amplitude mi′ of the seismic trace at a time-corresponding point i′ in the monitor survey and the amplitude due to the reflectivity change local to the time-corresponding point i′ induced by the difference between the first velocity field Vb and the second velocity field Vm; the time-corresponding point i′ being shifted in time by a time-shift derived from the velocity changes along the propagation path from the surface to time-corresponding point i′. This sum is minimized to characterize the evolution of the hydrocarbon reservoir and derive the velocity changes from the base survey to the monitor survey.

    • A method, apparatus, and computer instructions for managing versioning data for a state between a first virtual machine on a data processing system and a second virtual machine on a remote data processing system. Versioning information is stored in response to a request to generate a version in the first virtual machine. A request is sent to the second virtual machine for the second virtual machine to generate a corresponding version. The version and the corresponding version are used to restore the first virtual machine and the second virtual machine to the prior state. The prior state in the first virtual machine is restored using the stored version when a subsequent request is received to restore the prior state. A subsequent request is sent to the second virtual machine. This request requests restoring the prior state for the second virtual machine using the corresponding version.
