InterWell 2019
InterWell 2019 release brings new possibilities for inversion and characterization workflows, with two main additional features: the 2D data management and the multi-component inversion. Following the 2018 release, user experience is continually enhanced with clearer survey tree and menus, new useful functionalities in already implemented modules and a better integration of the 4D inversion workflow and more. This new version is now compatible in RedHat7 and Windows 10 Operating Systems. To ensure the compatibility of older studies, a survey migrator has been implemented, down to InterWell 2014 studies.
The first major evolution is the ability to load 2D Lines as input seismic data in InterWell honoring the navigation geometry, with a dedicated new seismic outline and 2D horizon display. The wells are automatically projected on the nearest point to be used in the wavelet estimation workflow and more. Full compatibility with existing modules, including the most advanced inversion workflows, is supported in this release.
Based on the most recent innovation from IFPen, the Multi-component workflow has also been implemented, with a more robust estimation of the density. Multi-vertical scale is now handled for InterWell survey geometry, one per wavefield domain. Sequential inversions, for each domain, are supported thanks to an update of the inversion algorithm. Registration law, to link a domain to the standard PP-domain, is based on two brand-new modules: Base Law and Residual Law. Joint inversion outputs a result in P-impedance, S-impedance and density in PP-domain, linked to existing key seismic characterization features to get the best of this new results.
4D inversion workflow is now available directly in 3D survey, without going to a 4D survey. It allows a better connection with all InterWell possibility; the ToolBox, the extraction, the discriminant analysis. Moreover, a new 4D quantification module is available, to capture the impedance variations between vintages in volume or in maps. Azimuthal workflow has been revised thanks to recent project experience and allows to extract the error of the ellipse fitting, key parameters to assess the uncertainty of the anisotropy analysis.
For the most complex structural contexts, the wavelet extraction can now be performed in a time window along a horizon. InterWell also continues to develop its seismic characterization capabilities with the brand-new AVO Analysis module, a fast-track analysis to measure the AVO effect on initial, aligned or synthetic seismic data. Discriminant analysis can be performed from 1 to 3 variables, and outputs a table to check the re-assignment of the training samples.
InterWell handles more data types with the integration of the arbitrary lines in the survey tree. Well data tree has been reviewed to better split the different well data along the inversion workflow. By integrating a new version of INTViewer, the wells can be broadcasted in neighboring InLine or XLine view and isolines can be displayed on horizons and maps.
