This tab has the following features:

Synthetic Panels - Displays the tracks for your synthetic. Read more.

Synthetic Curve Definition

Set the values in these boxes to define the filters for your synthetic. As you configure filter tracks in this section, you can add them to the Synthetic Panels window.

You have the following options:

Ricker Wavelet - This wavelet represents ideal viscoelastic behaviour. Set the period in milliseconds, with a default value of 26.0 milliseconds. You can instead change the peak frequency in Hertz, with a default value of 30.0 Hertz. Note that changing the frequency (or period) will automatically change the other value.

Ormsby Wavelet - Set the four frequency values. The frequencies must increase from Stop1 to Stop 2. The default values are:

Stop 1: 10.0 Hz
Pass 1: 20.0 Hz
Pass 2: 70.0 Hz
Stop 2: 80.0 Hz

Butterworth Wavelet - Set the low and high frequencies and the low and high slopes of the curve. The default values are:

Low Slope: 96 db/octave
Low Frequency: 10 Hz
High Slope: 96 db/octave
High Frequency: 40 Hz

Klauder Wavelet - Set the start and end frequencies of the sweep. Set the sweep length (10.00 to 100.00 seconds). Set the taper length (0.00 to half the sweep length). The default values are:

Sweep Start Frequency: 10 Hz
Sweep End Frequency: 70 Hz
Sweep Length: 10.00 seconds
Taper Length: 0.50 seconds
The Klauder wavelet is the auto-correlation of a Vibroseis sweep.

<Add> - Click to add the current synthetic curve definition to the Synthetic Panels window.

<Replace> - Select an item in the Synthetic Panels window, then click this button to replace that item with the current synthetic curve definition.

<Up> and <Down> - Click to move synthetic panels up or down in the Synthetic Panels window.

<Edit> - Select an item in the Synthetic Panels window, and then click this button to open that item in the Synthetic Curve Definition window, where you can edit it.

<Delete> - Select an item in the Synthetic Panels window, and then click this button to delete that item.

Method to Resample to Time - Select a resample method from the list.
Sample Interval - Select a sample interval from the list.
Log Depths - Select a format for the log depths.
RFC Computation - Select a method to compute the reflection coefficient.
<Edit Overlay Params> - Click to open the Synthetic Data Overlay Parameters dialog box, where you can adjust the appearance of your synthetic display.

The default source of the curve will be the checkshot (if available), or your sonic or top/bottom hole times.
