Creates and attaches features generated from seismic and data to training table.

NODE CREATION

Opening a workflow from the QApp workflow management section will direct you to the workflow canvas. Create and configure the node with the following steps :

  1. Choose the QEarth product from the list on the right side of the canvas.

  2. Select the Feature Engineering process from the process list.

  3. Choose Feature Engineering and configure settings according to the settings manual .

  4. Click "Save" if okay or "Cancel" to return to the workflow canvas.


Note: Only "Cancel" and "Save" options are available before new node creation.

SETTINGS PANEL

Clicking on a node in a workflow opens up the settings page of a node by default.

  1. Delete a node by clicking the Trash Icon (upper-right)

  2. Click LOGS to view the message and error logs for a node.(bottom-left)

  3. Click Cancel to exit node view.

  4. SAVE the node settings if new node or UPDATE node settings upon changes to settings.

Provides information about the node and provides a reference for the input/output compatibility with other nodes in QEarth.

  1. Input nodes: Compile Well Base, Import Horizons, Import Seismic

  2. Output Nodes: Create Data Model

LEGEND PANEL

SETTINGS

  1. Node Name: Enter a name for the node which will appear on the workflow canvas.


SEISMIC SAMPLING CONFIGURATION

  1. Length of Smallest Reflection: Length of the shortest cycle (trough to trough) in the zone of interest of your seismic. Provide this value in terms of samples. For example: If your shortest cycle is 40ms long and your seismic sample rate is 4ms, then you would enter a value of 10 in this field. For data in depth, the same principle applies.

  2. Length of Largest Reflection: Length of the longest cycle (trough to trough) in the zone of interest of your seismic. Provide this value in terms of samples. For example: If your longest cycle is 120ms long and your seismic sample rate is 4ms, then you would enter a value of 30 in this field. For data in depth, the same principle applies.


Horizon Based Zone Boundaries

  1. Top Band: Provide distance above or below the shallowest horizon in your dataset. Units are in the domain and sample rate of your dataset. Negative values translate your boundary shallower and positive values translate your horizon deeper. For example: Providing a -5 in this field for a time-domain dataset with a sample rate of 4ms would create a top boundary for your zone of interest that is 20ms above the shallowest horizon.

  2. Bottom Band: Provide distance above or below the deepest horizon in your dataset. Units are in the domain and sample rate of your dataset. Negative values translate your boundary shallower and positive values translate your horizon deeper. For example: Providing a 5 in this field for a time-domain dataset with a sample rate of 4ms would create a bottom boundary for your zone of interest that is 20ms below the deepest horizon.
