Description

|
Earthworks’ MPSI UltraFast stochastic inversion scheme is considered the
fastest stochastic seismic inversion scheme currently available. The method uses a prime factor FFT scheme to
generate the stochastic realizations in the frequency domain.
Stochastic inversion is
complementary to deterministic inversion. Stochastic inversion is used to understand the
uncertainty in seismic inversion, via the stochastic inversion utilities, and
allows the user to explore the impact of this geophysical uncertainty on the
lithology, porosity or reservoir volumes over the 3D
seismic volume inverted. For thin
intervals a stochastic inversion is particularly appropriate for understanding
uncertainty and reservoir volume and connectivity. It also allows the user to
improve the estimation obtained from a deterministic inversion as the mean of
many realizations (calculated using the utilities) will behave like a global
convergence solution from computationally expensive algorithms.
Because of its speed Earthworks’
stochastic inversion can compute the large numbers of realizations necessary to
capture the full range of uncertainty. A
typical Earthworks’ stochastic inversion would compute 100 realisations for subsequent uncertainty analysis.
