4 steps to building a seismic forward model

There are three ways to define the geometries for an earth model: use a scenario (classic Modelr workflow), build a simple model, or upload an image.


Integrated scenarios

To use the classic Modelr workflow, with self-contained scripts that describe the model, the experiment, and the display properties, use or build a Scenario.

Build a model

To build a simple model from scratch, either use the Model builder to make a new image, or use a predefined Scenario.

Upload an image

You can upload an image of a model. This way, you can make seismic from arbitrary models. To upload an image, use the Upload image button on the Model page.

Assign rock properties to each color in the model.

Define your own rocks

Each rock in modelr has a set of physical and statistical properties. You can define and manage a collection of your own rock properties from the Dashboard page, or you can use some of the public default rocks.

Use default rocks

Choose one of the rocks from the public default section.

Assign rocks to your model

Select rocks for each layer from your list of available rock types.
Choose acquisition domain: a cross-section (spatial), an angle gather, or bandwidth at a user specified trace location in the cross section). Future releases will allow accessing the 4 dimensional seismic model (x, t, angle, and bandwidth) in horizontal dimensions (i.e. a time slice through angle, bandwidth space on the x and y axis)
  • You can choose to display the synthetics seismic model, along with the layers or reflectivity values of the interfaces in the physical model. These can be used as underlays for directly comparing the positioning and resolution of seismic events.
  • The base layer for each panel is opaque, whereas the opacity of the overlay layer can be controlled.
  • Want to change the number of traces in the synthetic, the colormap, the number of wiggle traces to skip or the percentage of overlap? All of these parameters can be set in the scripting layer.
  • Give a name to your scenario, if you are happy with the results. This will save to your user profile, and you can come back to it later.
  • Along with returning an image of your model result, modelr also builds an equivalent URL that can be copy and pasted into any browser window, or attached to an email and shared with a colleague.
