Stochastic Seismic Inversion (an ARK CLS joint venture project with Earthworks)

Earthworks’ MPSI UltraFast stochastic inversion scheme is considered the fastest stochastic seismic inversion scheme currently available.

Full bandwidth model based seismic inversion technology.
Low cost, no fuss unlike most stochastic inversion algorithms which are slow, expensive or both. 
Available as an OpendTect pluginOpendTect plugin
Rapid, robust, inexpensive.

Product 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. 


MPSI Availabilty

Beta version of MPSI OpendTect plugin is now available for download. Full release of MPSI will be made available for download and evaluation in the 4th Qtr 2007. 

Application Support and Maintenance
With a support and maintenance contract from ARK CLS Limited, clients can download software updates in the form of new releases and patches.
