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 […]
OMNI 3D Workshop Tutorial: Interpreted Surfaces in 3D Models
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 […]
OMNI 3D Tutorial: Creating Target Files
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 […]
OMNI 3D Workshop Tutorial: 3D Ray Tracing and Analysis
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 […]
OMNI 3D Workshop Tutorial: Illumination Analysis over a Target Model

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 […]
OMNI 3D Advanced Tutorial: 3D VSP
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 […]
OMNI 3D Workshop Tutorial: Depth Analysis
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 […]
OMNI 3D Workshop Tutorial: Illumination Analysis over a 3D Ray Model
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.
OMNI 3D Workshop Tutorial: AVO Quick Start
This tutorial shows how to use the various analysis tools in OMNI 3D for determining the possible AVO response.
OMNI 3D Layout Tutorial: Converted Wave 2D Ray Model from Well Logs
