Time lapse inversion

Qeye's elastic inversion results benefit from proprietary 4DAVO friendly preconditioning.

Qeye simultaneously inverts angle stacks from multiple monitor datasets directly for the changes in elastic parameters.

Qeye delivers calibrated volumes of saturation changes that can be directly compared with reservoir simulations.
