Horizon Interpretation Manual, 2D auto-picking, polygon picking and drag-picking modes to quickly mark seed picks for horizons.

Advanced 3D horizon tracking using correlation or interpolation-based auto-pick methods with validation options. Display of horizon attribute maps like confidence, pick order and pick type and editing horizons based on pick attribute criteria.

Identification and elimination of potential bad picks using pick relationship displays. Multi-Z horizon picking for interpretation in thrust-faulted areas 2D seismic only. Fault Interpretation Picking faults by marking fault segments on 2D displays of vertical and horizontal seismic or directly in the 3D view. Automatic fault surface interpolation with robust fault triangulation algorithms delivers accurate and reliable results. Assigning, un-assigning or re-assigning fault segments individually or in bulk directly from the seismic section or 3D view.

Correlation window to assist fault picking in difficult areas or noisy data. Automatic fault heave calculation with fault polygons. Time to Depth Conversion Simple and accurate time-to-depth workflows with unique three-component horizons for time, velocity and depth data. Improved algorithms to build robust and reliable velocity models. GVERSE Geophysics supports four kinds of velocity models based on: velocity surveys of wells, horizons and formation tops combination, structurally interpolated time-depth tables and the ability to use an external seismic volume as a model.

Switching to Depth Mode in time interpretations to convert time scenes to depth on-the-fly. Integrated Mapping Multiple base maps with a unique set of display parameters and color palettes. Contouring maps or color density maps of time, depth, velocity or seismic attributes. Gridding and contouring with minimum curvature gridding or inverse distance algorithm for quick, interpretation maps. Planimeter and linear distance tools on Map and 3D views.

Attribute and Surface Calculation User-friendly Attribute and Surface calculator comprises multiple attribute options. Flexible windowing options to calculate attributes within a time window, between horizons or about a selected horizon Extraction of seismic data at well locations and save as a log curve in the active curve set. Enhanced Usability Showing contours on horizons in 3D View. Clipping the 3D scene to an area of interest AOI.

More control on hiding and removing items from a scene. Calculating distance between points or along a path on the map or 3D scene. Flattening of seismic data in a 3D scene with respect to a selected horizon. Marking horizons on flattened seismic sections.

Displaying fault polygons on a horizon. Calculation of single and multitrace attributes in Python. Also included is an attribute Mistie Application that will apply the corrections.

Free Software OpendTect OpendTect OpendTect is an open source seismic interpretation software system for processing, visualizing and interpreting multi-volume seismic data, and for fast-track development of innovative interpretation tools. Spectral Decomposition Spectral Decomposition is used for imaging and mapping temporal bed thickness and geological discontinuities.

Movie-Style Parameter Attribute parameters frequency, time gate or step out can be inspected in a movie-style way, to quickly find the optimal settings for your data. Distributed Computing Heavy processing of large volumes can be carried out in batch mode on multiple machines and on multiple platforms that can be accessed through the network. Horizon Tracking The horizon trackers support manual drawing, line tracking and 3D tracking of amplitudes and similarities.

Faults Fault planes and fault-sticks sets. Time to Depth conversion Use an existing velocity model, or create one with the new Volume Builder. Geobodies Insert an iso-surface in a volume rendered cube and save it as a geobody. Madagascar Processing OpendTect has a generic user interface to Madagascar , the open-source software package for geophysical data processing and reproducible numerical experiments.

Gap Decon A multiple removal tool through prediction error filtering. Horizon Attribute The Horizon attribute allows surface horizon data to be combined with cube data for calculations. Annotations Annotate seismic data with text-boxes, hyperlinks, lap-out arrows, and images.
