RGB Frequency Decomposition Blends are extremely useful in identifying both structural and stratigraphic events. These are best observed in the Z domain as the effects of vertical smearing are minimized. When observed along the inline or ...
When it comes to geomodel building, Fault Detect volumes of Geoteric can be used as input for a discrete fault network. There are, however, other measures that can be derived from this volume. The workflow discussed below creates a volume ...
This is the last part of our series on AVO screening in Geoteric. Scaled reflectivity is a volume that results from a rotation of the gradient-intercept crossplot using a certain χ angle. If the right χ angle is used, it will highlight ...
Gradient and Intercept volumes can be generated from the angle stacks as discussed in Part 3. The Gradient and Intercept volumes can be combined in a number of ways to generate different AVO attributes, such as AVO Product or Reflection ...
Geoteric's colour blending and volume comparison capabilities can be used very effectively to screen for AVO anomalies and get an initial understanding of areas where you want to focus on for a more detailed AVO analysis.
The simplest way of AVO Screening involves the computation of difference and ratio volumes to highlight differences in amplitude between stacks. This amplitude difference may represent lithological/fluid differences.
Polygons can be imported in ASCII format into Geoteric but also created on colour blends in the 2D colour blend viewer. The polygons created this way can be saved to the project tree and smaller polygons can be used to segment a colour ...
Horizon interpretation is known to be very time consuming. Therefore, the advantage of having the IPS tool is that an interpreter can interpret one or two bounding horizons, which could be non-parallel, put them up within the IPS tool and ...
