This tutorial shows how to create an EWE Analysis Model on a 2D Ray Model. SEGY files will be created in two different ways. Working with this Tutorial If you are new to OMNI 3D, please see the “Basic Land” tutorial before you use this tutorial. In this advanced tutorial it is assumed that you can: Start […]

This tutorial builds upon the skills learned in the tutorial “Building a 3D Model”. In Exercise 1 we created a theoretical grid and populated it with horizon data based on mathematical models. The mechanics of creating horizons, horizon relationships,positioning faults and viewing models were covered in detail. Exercise 2 builds upon these skills. The object of this exercise […]

This tutorial gives step by step instructions to create an OMNI 3D Target file Set parameters as described and illustrated. As you work,use OMNI 3D’s Popup Help to see explanations of all available parameters. Hover your cursor over a parameter or click the question mark in the upper right of a dialog and then click the parameter to […]

This tutorial builds upon the skills learned in the tutorials “Building a 3D Model” and “Interpreted Surfaces in 3D Models”. The object of this exercise is to ray trace a 3D model and calculate a target analysis. Set parameters as described or shown in pictures of dialogs. As you work, use OMNI 3D’s Popup Help to […]

This tutorial shows how to create an Illumination Analysis over an OMNI 3D Target Model. You can examine amplitude variability from bin to bin at your time of interest. Working with this Tutorial Set parameters as described or shown in pictures. As you work, use OMNI 3D’s Popup Help to see explanations of all available […]

This tutorial shows how to lay out a 3D VSP survey in a deviated borehole. You will use shot elevations in Depth analysis and Target Illumination. Set parameters as described or shown in pictures of dialogs.As you work, use OMNI 3D’s Popup Help to see explanations of all available parameters. Hover your cursor over a parameter or […]

This tutorial shows how to create a Depth Analysis for a survey. You will learn how to view a data cube on the 3D view tab. This analysis calculates and displays Stack Fold. That is, fold before migration. Traces are calculated by ray-tracing over a number of flat layers below the Survey. Traces are then […]

This tutorial shows how to create an Illumination Analysis over an OMNI 3D Ray Model. This is a very quick method for identifying areas of your target which may present illumination problems. Shot and Receiver elevations are used and curved rays are traced through the 3D velocity model.

This tutorial shows how to use the various analysis tools in OMNI 3D for determining the possible AVO response.

This tutorial gives step by step instructions to create a 2D Ray Model from a LAS well log file. You will also create a SEGY synthetic.
