Geoteric’s new Adaptive Horizons use regional structural awareness to create the fastest and most accurate 3D seismic interpretation. Any seismic, attribute or HSV colour blend volume can be used as a source for the Adaptive Horizons (which can be interpreted in both the 3D scene or using a 2D interpretation window), with different auto-track fill options ranging from Waveform, Amplitude, PDF and Graph Theory depending on the source data and objectives. A variety of tracking modes are also available: Full line, Piecewise and Manual, all with interactive previews due to the Regional Structural Awareness.
More details on these and other options are covered in the next blog
Geoteric’s Adaptive Horizon tool is based on graph theory to deliver the most accurate interpretation based on the entire line, not just the next trace along. Graph theory correlates all the points in the data and determines all the potential routes. The route with the highest score will be selected as the initial interpreted horizon. All the other routes are remembered creating the Regional Structural Awareness so the user can preview and choose alternative interpretations, which makes the process of picking a horizon quicker and easier.
The ability to preview the alternative routes in an interactive way allows the user to ensure the correct event is picked, for example when investigating cross-fault correlations as in the image below.
Other unique features such as “Complete Line” and “Accept Tracked Line” enable the horizon to be quickly QC’d and completed saving time and aiding efficiency whilst maintaining the accuracy of the interpretation.
The 3D editing capability of the tracked surface along with Data Mapping as you interpret greatly aids the interpreter in QC’ing the horizon. Any attribute or blend can be mapped prior to surface generation, to identify mis-picks and correct them in the 3D or 2D windows. In the example below, the Interpretation HSV colour blend effectively highlights mis-picks (in blue).
The interpreted horizons can be exported or integrated with other Geoteric functionality such as the Horizon Packs and the Stratigraphic Slicing workflow .
