ESI uses Petrel objects to define the inversion session
Extract and analyse geobodies over multiple inversion realizations (Petrel)
Earthworks native integration with DecisionSpace
Set up your inversion sessions through a familiar and easy-to-use interface, using native components in the host platform (Petrel™ or DecisionSpace™).
Petrel™ Plug-in Interface.
Earthworks native integration with DecisionSpace™
ESI delivers stochastic and deterministic inversion on pre- and post- stack seismic data. Deterministic inversion gives a smooth best estimate of the impedance whereas the stochastic inversion realizations give a broadband output that models geophysical uncertainty.
Ultra-fast, full featured seismic inversion software.

Software - ESI

Earthworks Seismic Inversion The Earthworks Seismic Inversion (ESI) plug-in is ultra-fast, full-featured seismic inversion software that enables effective use of impedance data in your geophysical and reservoir modeling workflow. It is a fully integrated part of the host platform and uses native data objects. The inversion technology at Earthworks has evolved over the last 10 years to provide a solid and reliable solution that has been used in several hundred projects. It delivers stochastic and deterministic inversion on pre- and poststack seismic data. Deterministic inversion gives a smooth best estimate of the impedance whereas the stochastic inversion realizations give a broadband output that models geophysical uncertainty. The inverted acoustic or elastic impedance results are commonly used to better understand the porosity, lithology and fluid saturation distribution in your reservoir model. It can also be used to produce more accurate and detailed structural and stratigraphical interpretations. The ESI™ plug-in is fully integrated into the host environment and adopts the platform user interface, giving you ultra-fast seismic inversion on your desktop.

FUNCTIONALITY HIGHLIGHTS

Model-based deterministic inversion on pre- and post-stack seismic data Stochastic inversion on pre- and post-stack seismic data 3D geostatistical parameterisation of models Spatial data dependency controlled by 3D anisotropic varogram functions Fast, interactive testing of seismic inversion parameters prior to launching inversion runs Single stacked seismic volumes or any number of angle stacks can be supported, depending on the inversion algorithm selected Wavelets can be extracted using the host platform tools or imported from other packages Layer constraints can be defined using structural horizons or surfaces in the host platofrm database Wells and well logs can be specified as part of the input and depth trend functions can be applied to remove unwanted effects Inversion results can be stored as impedance volumes ESI sessions can be stored as part of your project Stochastic inversions can be run as individual threads, so taking advantage of multiple CPUs Large inversion jobs can be run in a background process to free-up licenses *Note: Some features are host platform specific
